Preface

Welcome to the Mathematics for All (M4ALL) toolkit designed to support educators in teaching Mathematics topics from the primary school curricula to special needs students. This manual is a culmination of extensive research, collaboration, and practical experience aimed at equipping educators with the necessary tools, strategies, and resources to foster an inclusive and supportive learning environment.

Teaching students with special needs requires not only a deep understanding of diverse learning abilities but also a commitment to adapting teaching methods to meet each student’s unique requirements. The purpose of this manual is to serve as a valuable guide for educators, enabling them to create individualized, effective, and engaging learning experiences.

Purpose and Scope

The primary goal of this toolkit is to provide a structured and accessible collection of training resources that address the diverse needs of special education students. It comprises 46 lesson plans for teaching difficult topics in Mathematics at primary school level. The toolkit also contains supplementary materials which support and enhance the presentations of the different topics.

Acknowledgements

This manual has been developed with the invaluable input of educators and practitioners from primary schools and the special education community. We extend our heartfelt gratitude to everyone who contributed their expertise, insights, and experiences to this project. Special thanks to all the primary school teachers from Bulgaria, Portugal and Turkey who piloted the lesson plans and developed their own lesson plans. Their role of peer reviewers who ensured that the content is accurate, relevant, and practical was of major importance for the success of the project.

How to Use This Manual

We recommend starting with SEN Power Methodology to build a foundational understanding of one of the target groups of the project, namely students with specific learning difficulties, autism spectrum disorder and attention deficit hyperactivity disorder. As you progress through the manual, you will find two extensive collections of suggestions for introductory activities (energizers) and closing activities (relaxing activities) which appear later in the lesson plans but you can opt for replacing the suggested ones in the lesson plans choosing from the two collections. Then, you come to the 46 lesson plans which provide step-by-step instruction of how to present the topics to all students, but considering the specifics of the students from the target group. Each lesson plan is designed to stand alone with the concrete topic and a reference to grade it is meant to be used in, allowing you to easily reference the material as needed.

Interactive elements and practical tips such as using manipulatives, real-world examples, worksheets, videos and e-games are included throughout the toolkit to reinforce learning and provide hands-on experience.

Our Vision

We envision a world where all students, regardless of their abilities, have access to quality education that empowers them to reach their full potential. By using this toolkit, we hope you will feel more confident and equipped to make a meaningful impact in the lives of special needs students.

Thank you for your dedication and commitment to inclusive education. Together, we can create a more equitable and supportive learning environment for every student.

Introduction

“It was in the mid-90s that neurodiversity as a formal concept and a rights movement began to emerge. Aided by the internet, autistic people and those with other conditions were able to connect and began sharing their experiences: what they had in common, how their lives differed. A recurring theme was how many felt marginalised, pushed out of a society that embraced only typical ways of being in the world. The phrase “neurological diversity” cropped up in their discussions, which along with “neurodiversity” appeared in magazine articles later that decade.

Neurodiversity has clear parallels with biodiversity. It champions difference and the validity of individuals. It holds that a vaguely defined majority can be described as neurotypical, with brains that operate in a broadly similar way. Others, meanwhile, are neurodivergent, with brains that are built and work somewhat differently.

Neurodivergent people may be diagnosed with a range of conditions, and many co-occur in the same individual. There is no definitive list, but autism (and what was once known as Asperger’s syndrome) and attention deficit hyperactivity disorder (ADHD) are common, as are dyslexia, a learning difficulty that affects reading and writing, and dyspraxia, which manifests as difficulties in movement and coordination.”

Ian Sample Science editor, The Guardian

The SEN Power project team fully shares the ideas and findings of the article (read the full text here). We believe that You can teach everything to everyone but not with the same means and not for the same time. This is how we came up with the SEN Power project idea and the design of the M4ALL toolkit.

Instruction to teachers

Dear  Educators,

The “SEN Power” project was developed as an effort to support all students (but especially students with specific learning difficulties, with autism spectrum disorders and hyperactivity/attention deficit disorders) so that they learn better topics from the Mathematics curricula. It is addressed to students aged from 7 to 11 years old and their teachers. 

...

In the SEN Power project we designed the present teacher’s toolkit Mathematics for All (NS4ALL) where you will find detailed lesson plans and all accompanying materials needed to present the topic to your students. The activities make use of non-formal education teaching approaches. Using them in class may be stressful at the beginning. The following words of advice could significantly help you in order to properly implement the trainings.

  • Do not use any teaching methods, which you, yourself, are not ready to participate in.
  • Prepare carefully for the training sessions. Give clear instructions, consider the dimensions and predict the possible turns the activities and discussions may take, although it is not possible to predict all probabilities.
  • Each innovation encompasses a possible rate of failure. Though a well-prepared method could limit such probability, you have to keep in mind that the more methods you use the easier it will be for you to implement methods from non-formal education.
  • Every time you introduce a new method, you can increase the chances for success if:
    • you introduce what you have planned in a specific manner arousing students’ curiosity.
    • you accept the way students think and function even if this way is not the one you expected or aimed at. The solution is to intervene in the improper behavior of a student without rejecting them at the same time.
  • Consider all the objectives that can be achieved when using a specific activity or method. For example, an energizer can be used to stimulate the students but at the same time it could also generate the following positive effects:
    • it can improve children’s communication;
    • it can contribute to the ability of students to accept responsibility;
    • it can help creating a nice atmosphere in the classroom.
  • If you have applied a new teaching method for the first time and it was unsuccessful, this does not mean that this method cannot be effective in the future. On the contrary, try to learn as much as possible from this experience in order to be better prepared next time.
  • You may be puzzled and worried by the fact that the use of active learning methods causes mess and you feel you are losing control of the class. You must bear in mind that applying new teaching methods presupposes a different kind of control. When students work with a variety of methods it is natural that the teacher is not continuously in direct contact with them. The general intervention strategy must be clear and you should be able to intervene when necessary.
  • Consider the sufficiency of time made available for each training resource, as well as the appropriateness of the space you have in the classroom for applying the specific method (size, furniture arrangement and proximity to other classrooms).
  • Last but not least: Relax and have fun! After all this is what Non-formal Education is about!

Class preparation for the training course and the training  sessions


 

The HOPES&FEARS/ GROUP CONTACT session is to be held at the beginning of the school year prior to the planned training sessions making use of the resources in the Teacher’s Toolkit.

Hopes & Fears / Group Contract

>

Topic / Activity Name

Hopes & Fears / Group Contract

Duration

35 min

Aim / Objectives

  • To clarify objectives and expectations of students
  • To clarify the “rules” and the “values” of the group
  • To create a safe learning environment
  • To facilitate participants' communication on different levels.

Preparation

  • Suggested Reading, Tips, etc.
  • Materials

Materials:

  • For Hopes & Fears
  • Post-it notes in two different colours, i.e. yellow and blue (one for hopes, one for fears)
  • 2 large size carton papers in two different colours (one for hopes, one for fears)
  • Markers
  • Sticky tape to stick cartons at wall
  • Relaxing Music (optional)
  • For Group Contract
  • Large size carton or flipchart paper
  • Markers
  • Sticky tape to stick at wall
  • Tips

The teacher can ask students (prior to this introductory exercise, during a break or Arts lesson) to draw on the 2 carton papers something that symbolizes HOPES (i.e. an island with calm sea surrounding it, a tree etc) and FEARS (i.e. a scarecrow, a thunderstorm etc).

Introduction

This exercise should be done as an introductory exercise, so that students would begin to have an “idea” of what is going to happen in the next following weeks or months.

Methodology

Hopes & Fears

The teacher sticks on the wall the large-sized cartons with the two drawings and explains that one of the drawing stands for the hopes that students have on training course and the other one stands for their fears.

Each student gets 2 posts-it notes; one yellow, one blue. Students are instructed to write their expectations/hopes about the training course on the yellow paper and their fears on the blue paper. Once they everybody is ready, they go altogether at the cartons stuck on the classroom walls and stick their posts-it notes on them. After that everybody goes back to their seats. Firstly, the teacher reads the hopes (he/she can categorize them if there are similarities). Then she/he reads the fears (which also could be grouped).

Finally the teacher explains to the students that their post-it notes with the Hopes & Fears will remain on the wall until the end of the training course.

                                                                                                  15’

At the end of the training course, the teacher asks the students to have a look again at their Hopes & Fears and reflect on them. Did their fears have grounds? Were there issues that had been overcome? Has the project met their expectations?

Students can have a small conversation on the plenary and discuss their Hopes & Fears and what might have been organized in a different way.                                                                                               10’

Group Contract

The teacher discusses with students that this training course (project) will help them learn more about Human Rights, Diversity and Social inclusion, and Active Citizenship and Social Involvement in a different way compared to what they are used to. Activities will be shaped like games and they will be very practical. Since the group will be together in the training course (project) for several weeks or months, it would be good to establish together specific rules which everyone knows and respects.

The teacher guides the conversation and the students brainstorm about the rules they want to establish, for example: everyone’s opinion will be respected, there will be no judgment of opinions, everyone will respect silence when it is required,  participation is important because the activities are linked to all students as members of the group (class), etc. The teacher or a student writes all the “rules” on a carton paper or a flipchart. Once the list is ready, all students sign the Group Contract and it is stuck on the wall until the end of the project (training course).                                         15’

Opening a training session

We all know that if you eager to do an activity and start doing it with positive expectations, the outcomes are far more likely to be better and the intervention – to be more efficient. Students may come to class either with great interest, or not be interested at all. Sometimes the teacher may face notable resistance if he/she begins directly with the planned theme. The students in the class may at first need to calm down or to be stimulated. There is a series of methods that can be used to start a training session:

  • Begin with an energiser to evoke the students’ interest (as suggested on the toolkit).
  • Use a relaxation exercise or appropriate music when children are very unquiet (as suggested on the toolkit).
  • If students are facing a problem, then perhaps it would be better to deal with it at first. In practice you may discover that this particular issue can cover the entire activity although it was not planned.


Closing a training session


At the end of each training there must be time left to connect and close the issues raised, and students must have time to prepare the topic for the next training session. It is important that nothing is left hanging in the air. All issues should be properly resolved. The activity should also be closed by making positive comments on:

  • what has been achieved
  • the dynamic of the team
  • the progress made
  • the significant facts established by the team
  • any unusual incident that may have occurred
  • the work to be prepared for the next training session (depending on the training that follows).

NON-FORMAL EDUCATION

Teaching methods

In European projects – particularly within the frame of Erasmus - it is preferable to apply non-traditional teaching methods, which create a pleasant atmosphere in the class and turn learning into an interesting experience. In order to choose a method we have taken into consideration the aims of the resource. An appropriate method encourages students to identify situations in the reality of daily life and it gives them the opportunity to discuss issues as seen from their perspective. To ensure success of the method it is necessary to prepare it in the right manner.

This manual consists of 38 resources distributed in three modules: Children’s Rights - Human Rights; Diversity and Social Inclusion; and Identity, Active Citizenship and Social Involvement. Each training resource consists of two tools: (a) Non Formal Education (NFE) Tool and (b) Digital Tool (DT). The NFE tool describes the “exercises” (activities) which should be utilized with the group. The DT is an extra tool which is to be used to enrich the NFE tool. Depending on the resource, the DT could be used either prior, during or after the implementation of the activities. The NFE tools used are somehow “repeatable”; the same tool (method) can be used in a variety of resources. The same principle accounts for the DT’s.

The methods (NFE tools), which are applied in the present toolkit, are described below:


1. Team work

It has been established that team work in small groups of 4-6 students is a very effective working method. In small groups students have the opportunity to acquire knowledge, to comprehend and apply such knowledge while shaping attitudes and making choices. By discussing, participating and communicating in the group, students can develop and exercise appropriate skills.

Organizing the class into small groups can be achieved in different ways:

The educator explicates an activity and students shape small groups of 4-6 persons in which they practice different activities.

  • The activities could involve discussion, artistic creation, presentation, video making, role playing, brainstorming, simulation etc. All these activities could be utilized through team work, where the key element is the same; working in small groups.

The educator introduces the topic, students discuss it in groups and present their conclusions to all members of the class.

Students could work individually and afterwards discuss their conclusions in their group.

By discussing in the class, an issue is raised and students are divided into small groups in order to discuss and propose solutions.

2. Brainstorming

Brainstorming is a creative method aiming at expressing a variety of ideas. It can be applied for several reasons; most commonly it is used in order to cover as many aspects of the topic under discussion as possible.

Brainstorming does not mean simply asking for ideas from others. For an effective brainstorming session there are a few rules to be followed:

  • the question or topic must be well defined;
  • team members are encouraged to express any idea crossing their mind as an answer to the question. No one should comment on the others’ ideas. We insist on it.

Brainstorming is quite simple to utilize. The educator writes the topic or question on the blackboard, then explains the rules to the class setting a time limit, e.g. 5 minutes. Students are asked to begin. The educator writes the ideas on the blackboard quickly. If there is a gap established, the educator can fill it in his/her ideas. Depending on the  ideas, they could be categorized, i.e. a few ideas could fall under the same “major” category.

The next step is to process the ideas and move on to action. In some cases it may be necessary to ask students to specify some ideas. At this stage some ideas can be clarified, evaluated, chosen and ranked. This procedure is necessary in order to differentiate the ideas, i.e. if there is no differentiation during acceptance of ideas, there will probably be the impression that all ideas are equal and acceptable.

12

senpower
3. Role-playing games

In role-playing games a certain situation is carried over from the real world into the frame of the role-playing game. Role-playing games are useful when we wish to analyze certain behaviors or to test new or alternative behaviors within a controlled and safe framework. In order to use the role-playing games it is necessary to have a warm and open-minded atmosphere in the class.

It is important that all participants are aware of the meaning of the role-playing games and that they agree on certain basic rules in order to work together in a structured manner. Therefore, the educator has to explain in brief the methodology of the role-playing games and further on, the class has to set some rules for the students playing the roles, and for the students watching the performance, before the game starts. Then, the topic is defined as a certain situation and the participating characters are described in detail in order to help all participants to understand their roles. The different scenes should not last longer than a few minutes.

Students, not participating actively in the role-playing game, function as observers and they are the audience. The educator acts as the coordinator or “director” and he/she is responsible for planning, carrying out and evaluating the activity.

4. Simulation
A simulation game (Patricia K. Tompkins, 1998) is a recreation of a real-world situation, designed to explore key elements of that situation. Similarly to role playing, simulations always include an element of role. During a simulation game the students need to perform a certain situation based on real life situations, while in role playing the participants represent and experience some character type known in everyday life.
5. Artistic creation (drawing, painting, collage)Certain forms of art are a useful non-formal teaching approach within a group. Students do not just discuss or write about different social situations, but they also capture and express these situations in paintings, drawings, performances, etc. They can also make collages to express themselves and their opinion without requiring a certain talent or specialized skills. It is important that students overcome their fears regarding artistic creation. Therefore, the educator should spend some time in order to make students understand that the aim of the activity is not to create a work of art but to  express themselves in a free manner.

6. Case study

A case study (UNSW Australia) is an account of an activity, event or problem that contains a real or hypothetical situation. Case studies can be used in order to help students understand how the complexities of real life influence decisions. A common case usually:

  • is taken from real life (but it can be hypothetical);
  • consists of different parts and each part usually ends with problems and points for discussion. There may not be a   clear cut off point to the situation;
  • includes sufficient information for the reader to treat problems and issues;
  • is believable for the reader (the case contains the setting, personalities, sequence of events, problems and  conflicts).

A case study is given to students as an example in order for them to implement an exercise, while at the same time trying to focus on the issue described.

*All material used for the purposes of this project is located on the project’s website. Educators, and in some cases students, will be instructed to use the materials given in the description of each resource.

7. Guided Drama

In guided drama students are presented a case as far as general settings and characters are concerned. They are guided through the framework of the plot by receiving descriptions of planned events (meetings) and of their tasks in the respected meetings (messages). They are encouraged to step in the shoes of the characters and, keeping to the provided information, are free to decide on the story, i.e. details of the plot, characters’ speech, etc. The printed information is distributed to the students shortly before the events; students read it and plan their actions and speech right away, similarly to ‘speed dating’ techniques.

8. Mind Map

A mind map (Wikipedia) is a diagram used to visually organize information. A mind map is often created around a single concept, drawn as an image in the center of a blank page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those. Mind maps can be drawn by hand, either as "rough notes" during a lecture, meeting or planning session, for example, or as higher quality pictures when more time is available.

9. Blue skies thinking
Blue skies thinking is a well-known and widely used interactive method for generating ideas. It encourages participants to use their imaginations and be creative. It helps elicit numerous solutions to any given problem; for example, ‘what should I do in this situation?’ or ‘how can we overcome this obstacle?’. No evaluation of any kind is allowed in a ‘thinking-up’ session. If you judge and evaluate ideas as they are expressed, people will focus more on defending their ideas than on thinking up new and better ones. Everyone is encouraged to ‘think-up’ as many ideas as possible. ‘Wild’ or different
ideas should be encouraged even though they might sound foolish.
Participants should build upon or modify the idea of others.
How to do blue skies thinking?

14

senpower
  • Seat the participants informally;
  • Provide a flipchart pad or blackboard for recording ideas;
  • State the problem or issue to be addressed;
  • State the ground rules: for example, no evaluation of ideas is allowed, and no judgment as to worth.

The more ideas, the better; strive for:

  • quantity and build upon the ideas of others (combine, modify, etc.);
  • Ask for ideas and record them as fast as they come – do not edit them;
  • Encourage new ideas by adding your own;
  • Discourage derisive laughter, comments or ridicule of any ideas;
  • Discuss and evaluate the ideas generated.

10. Snowballing

Snowballing enables participants to think about their own responses and gradually reach out to those around them to consider the thoughts of others on an issue.

How to do snowballing? The teacher asks a question and/or poses a scenario and gives the participants a few moments to reflect. Then, participants are asked to turn to the person next to them and discuss their thoughts. Depending on the activity, the teacher may ask participants to prioritize their ideas, come to consensus on their top priorities, etc. (allow several minutes). Then, each pair turns to another pair and discusses their thoughts.

USE OF DIGITAL TOOLS

The digital tools that are shown in this toolkit are specifically chosen and designed for the purposes of the SEN Power project. The lesson plans describing the training sessions are enriched with one or several e- resources (digital tools), which are aimed at helping students learn about the respective topics in a more efficient and fun way. Depending on the training session, the e-resources from the Digital Tool can be used prior, during or after the implementation of the activity (instructions are given in each lesson plan).

The e-resources from the Digital Tool are uploaded on the project’s website and students can watch, play, learn, investigate through the use of films, online quizzes/questionnaires, interactive games, animation cartoon videos, prezi/ppt presentations etc.

EVALUATION

Evaluation is the process of estimating the effectiveness of a training course and it should be an integral part of every training and learning procedure.

Evaluation deals with:

  • the extent the training course (project) as a whole meets its objectives,
  • assessment which specific methods turned out to be effective for the fulfillment of the goals
  • tips and recommendations for upgrading the evaluated items so as to meet the users’ needs.

Evaluation activities are carried out in order to examine:

  • Appropriateness: Does the training course meet students’ needs, interests and anxieties?
  • Effectiveness: Does it achieve the aim and objectives that it was designed for?
  • Methodology: Are the suggested activities and methods the appropriate ones?
  • Coordination: Does the team coordinator in the school have the skills to communicate and work together with the team members in order to facilitate the learning process?

What is to be evaluated?

  • Contents: Is contents structured to meet students’ needs, interests and anxieties and ensure achieving the aim and objectives?.
  •  Organization and presentation: Are the described activities in the lesson plan organized logically and presented clearly using multiple methods and modes that motivate and increase openness to the diversity of the world and foster students’ social involvement skills as they engage in high interest, practical activities?
  • Instructional design and support: Does the instructional design use research-based instructional strategies and provide opportunities to engage in high interest, age-appropriate activities that mirror real-life situations, and make cross-curricular, global connections?
  • Equity and accessibility: Are the suggested activities and e-resources free from bias in describing ethnic groups, gender, age, disabilities, cultures, religion, etc. Do they consider multiple learning styles and the trainees’ cultural differences?

Energizers



senpower


























* The suggested energizers are different and some of them could take longer, but, as a rule, they are expected to last only a couple of minutes.
With the preparation and the time needed to launch and do the described energizers, this is estimated to last 5 minutes.

18

senpower
Energizers senpower 1 - Break the Circle

The teacher assigns randomly a number to each student, depending on the group size, i.e. for 20 students, numbers 1-4 are ok, so each group has 5 people (groups could be synthesized by the students with the same number, i.e. all having been assigned number ‘1’ or by students where each one has his/her own unique number 1-4; similarly and more fun is grouping by ingredient for a Greek salad, where every student is i.e. ‘tomato’, ‘cucumber’, ‘onion’, ‘oregano’, etc.) Once the groups have been formed, they make  circles and the teacher randomly picks a number (or an ingredient) to step out of the circle and try to break in, while the others remaining are instructed to not let go of their hands no matter what. This can be repeated once more with another number stepping out.

Energizers senpower 2 - Moo!!!

The teacher assigns randomly in a piece of paper (turned upside down on their desks)  each student with farm animal, i.e. ‘cow’, ‘horse’, ‘sheep’, ‘rooster’, etc. Once the students are informed of their animal role, they are instructed to walk around the room acting like the animal they are assigned (i.e. making its sound), in order to find their kind.

Energizers senpower 3 - Amoeba

An evolution game! Everyone starts off as an amoeba, with the purpose of evolving to a human. All students walk around acting like an amoeba and when they meet with another amoeba, they play one round of rock/paper/scissors. Whoever wins evolves into a worm. When two worms meet they play again rock/paper/scissors and whoever wins turns into a wasp, but whoever loses goes back to becoming an amoeba. This continues until one becomes human. The evolution stages are: amoeba à worm à wasp à chicken à monkey à human.

Energizers senpower 4 - Human chain

Everybody stands up in a circle. They close their eyes and start moving towards the middle of the circle, holding their hands up. Whoever they touch with their hands, they hold and do not let go, so they make a knot. Then the facilitator asks the students to open their eyes and try to untangle themselves (make a circle) without letting go of their hands.

Energizers senpower 5 - Good morning or good evening

Everybody walks around the room greeting each other (as if everybody was their close friends) using words and gestures (shake hand, kiss, hug). Then they repeat the greeting in silence using only their eyes. When the exercise is over, the teacher asks students how did they feel with the two different ways of greeting (eg was it difficult, how did they manage to communicate, etc).

19

senpower

Energizers senpower 6 - Keep walking

The teacher instructs the students to walk in different manners covering the whole rook, i.e. walk like you are very happy, walk like a very heavy elephant, walk like you are 80 years old, walk like it’s raining cats and dogs, walk like a toddler, etc.

Energizers senpower 7 - Connecting eyes

Participants stand in a circle. Each person makes eye contact with another person across the circle. The two walk across the circle and exchange positions, while maintaining eye contact. Many pairs can exchange at the same time, and the group should try to make sure that everyone in the circle is included in the exchange. Tip: Begin by trying this in silence and then exchange greetings in the middle of the circle.

Variations: If the teacher considers, knowing the class atmosphere, that some students might be left not participating, i.e. they try to make eye contact but nobody responds to them and they have no chance to move from their initial position, the moderator could divide the class in 2 groups and introduce a competitive element – after the activity each group will be marked on the ‘team spirit thermometer’ (which could be printed on a A4 paper and the teacher marks the degrees with a marker). The more people you have left not participating in the ‘eye contact’ activity – the lower the degrees to be marked on the thermometer.

Energizers senpower 8 - Find another seat:

Have the students sit on chairs in a circle, with the number of chairs being one less than the number of students. The student without a chair stands in the middle and tells their name. Then the student calls out a characteristic or a colour, or type of clothing, e.g. “Everyone wearing orange!”. All participants who are wearing orange must get up and find another seat, but not the one immediately to their right or left. The student in the middle races to find a seat and the person left standing becomes the next caller in the middle.

Energizers senpower 9 - Balloon pop

Have everyone form a circle. Instruct the participants to put one piece of information about themselves, e.g. I have 2 sisters, or my mother is called Samy,  on a small slip of paper, fold it, and put it in a blown up balloon. Throw the balloons in the middle of the circle and then have people take turns popping a balloon, reading the piece of paper, and guessing to whom the information applies. Participants could wander round the room asking ‘yes/ no’ questions to the other participants but not exactly the statement from the paper slip, e.g. they cannot ask “Have you got 2 sisters? But could ask “Have you got sisters?” and then “Have you got more than 1 sister?’, “Have got less than 3 sisters?”, etc. Game finishes when all participants have identified the author of the paper slip they have.

*Note: this exercise should be used if there is enough time.

20

senpower

Energizers senpower 10 - Rope game

Have the participants stand on the middle of a space cleared of desks, chairs, etc. Divide the room in a way that allows them easily to move from one half of the room to the other, e.g. by placing a long piece of rope on the floor. The teacher stands at one of the ends of the rope and calls out a characteristic, or a colour or a letter, e.g.  “Everyone having blue eyes!”; “Everyone having 3 brothers”, “Everyone whose name begins with B”, etc. and points to the part of the room where the participants wearing orange/ having 3 brothers/ having B names have to move to. All participants who are wearing orange/ having 3 brothers/ having B names move to the respective part of the room; the ones who are not , have to go to the other part. Questions have to be constructed so that the class does not divide in groups having comparatively equal number of students, i.e. one of the groups should consist (in most cases) of one, two or few students. Debriefing: Participants are asked to share how they felt when they were part of a big group; and when they were standing alone (or were part of a very small group); what did they feel of themselves (as part of a small/ big group), and what their feelings were towards the group they were not part of.

Energizers senpower 11 - Alphabetical order

Students make a circle with the chairs, take off their shoes and get on the chairs (one per person - the circle needs to be as close as possible). Standing on the chairs and just moving from one to another one without getting off, students have to arrange themselves in alphabetical order according to their name. As soon as they are ready, teacher will check if they are right; if not they continue until they are right. 

Energizers senpower 12 - Body spelling - Body geometric shapes

Option 1

The teacher asks students to write their names in the air using different parts of their body, for example, using their hand, leg, lbow, or nose, etc.

Optional: If time allows the teacher could ask to the class to spell out some words reproducing the letters with their bodies. Students can collaborate all together or can create different groups.

Option 2

Task: Draw a geometric shape in the air using different parts of your body - hands, legs, elbows, noses, etc.

Option 3:

Task: Work in groups of 2, 3 or more students to make a geometric shape with your bodies.

Energizers senpower 13 - Simon says

Teacher tells the group that they should follow instructions when he/she starts the instruction by saying “Simon says...”. If the teacher does not begin the instructions with the words “Simon says”, then the group should not follow the instructions! The teacher begins by saying something like “Simon says clap your hands” while clapping their hands. The participants follow. The teacher speeds up the actions, always saying “Simon says” first. After a short while, the “Simon says” is omitted. Those participants who do follow the instructions anyway are ‘out’ of the game. The game can be continued for as long as it remains fun.

Energizers senpower 14 - I am going on a trip

Everyone sits in a circle. Start by saying “I’m going on a trip and I’m taking a hug”, and hug the person to your right. That person then has to say “I’m going on a trip and I’m taking a hug and a pat on the back”, and then give the person on their right a hug and a pat on the back. Each person repeats what has been said and adds a new action to the list. Go round the circle until everyone has had a turn.

Energizers senpower 15 - Animal roundup

The teacher tells to the class to silently think of an animal. Then he/she tells to the group that without talking, they need to arrange themselves on a line from largest to smallest animals. Group members can only make gestures and the noise of their animal. After they have finished, teacher ask to the students to say the animal they were supposed to be to see if the order is correct.

Energizers senpower 16 - Back to back

Participants find a pair of similar size and weight. They sit on the floor, back to back with their pair. They hold their arms.  They have to get up, while keeping the arms and backs together. After trying once-twice with their pair they switch pairs. They can repeat this process with other pairs for a few times.

Energizers senpower 17 - Toaster or Rock Star

The group starts in a circle with one person in the center. The person in the center points at someone in the circle and says “Toaster” or “Rock star”.

  • If the person in the center says “toaster”, the person being pointed at needs to crouch down and jump up and say “butter me I’m done.” The people on either side should arms up and out strait creating a “toaster” around the person being pointed at.
  • If the person in the center says “Rock star”, the person being pointed at needs to hold his/her hands in front of their mouth as if he/she were singing into a microphone. The people on each side turn away from the person who’s been pointed at and pretend to play the guitar.

Energizers senpower 18 - Mosquito game

The group stands in a circle and the facilitator tells a story about a plague of mosquitoes and that everybody has to kill the mosquitoes so as they don’t get malaria. The facilitator puts up a mosquito on the head of a person who must lower in order to avoid the mosquito. The two persons next to that person must clap their hands above his/her head to kill the mosquito, but the mosquito escapes and it goes on. When the group is already doing the game well and quickly, the facilitator will add more mosquitoes until it is almost impossible for the group to catch as many mosquitoes.

Energizers senpower 20 - Chief of clan

Everyone stands in a circle. One participant closes his/her eyes or steps out of the room. He/She will have to guess who is the chief of the clan. One participant volunteers to be the secret Chief (quietly, so the "guesser" can't hear anything). The chief begins an action such as snapping fingers, patting the tummy, or slapping knees, and everyone in the circle imitates him/her.  The guesser returns to the room and tries to figure out who the chief is. As the guesser looks around, the chief changes the action avoiding being detected.

Energizers senpower 21 - Name game with balls

Students stand in a circle. The teacher gives a ball to one of the students. He/she holds the ball, then says the name of another participant and passes them the ball. After a few passes, the teacher adds one more ball in the game, and then – another one. This way there will be 2/3/4 balls in the air at a time and all participants will be calling each other’s names

Energizers senpower 22 - Names and adjectives

Participants stand in a circle; they think of an adjective to describe character or how they are feeling. The adjective must start with the same letter as their name, for instance, “I’m Maria and I’m merry”. Or, “I’m Alexander and I’m amazing.” As they say this, they can also mime an action that presents the adjective in a meaningful way. (N.B. In the national language versions of the TM there should be used popular names for the country and relevant adjectives in the respective language).

Variation (use if time allows): The game could also be used a memory game (concentration game) to check if the rest of the group has remembered the ‘name-adjective’ pairs. After several rounds (each participant repeating his name and adjective, the teacher/ a game master, checks if the group remembers the ‘names-adjectives’ fixed pairs by saying the name of one of the students, e.g. ‘Maria’; Maria steps forward to the middle of the circle and the rest of the group are expected to come up with the adjective previously linked to the name by saying “Maria is merry”. If they cannot guess, the participant in the circle (Maria) might mime again the adjective as a tip.

Energizers senpower 23 - Emotions Games

Materials required:

  • Medium size ball
  • 5 A5 size cards with the faces of the emotions.

Move the tables and chairs around the classroom, so the students can sit in a circle.

The game begins with a ball being thrown to a student, at this point the leader who has got the 5 cards (one for each emotion), raises a card; the child who has received the ball must talk about a situation that triggers the emotion that the leader has raised. The ball is then thrown to another classmate and so on until all the students have received the ball and all of them have had a chance to talk about an emotion.

The ball can only be thrown once to each student.

The game ends when all students have received and thrown the ball and all of them have spoken about an emotion.

Energizers senpower 24 - How much do we weigh?

Divide the students into groups of 4

Material 

Record sheet (appendix 1)

Digital bathroom scales.

Move chairs and tables so that you can have as much as free space in the room as possible.

The students are divided into groups of 4, made up randomly but heterogeneously.

Each group is given a record sheet and a digital bathroom scale (borrowed from parents, if necessary).  Each student will weigh him/herself and record the required data on the record sheet. After this procedure, the students in each group should line up in a row, from the lightest to the heaviest. The group that completes the task correctly as soon as possible wins the game.

Energizers senpower 25 - The mirror game

The game begins with the room cleared of tables and chairs.

The students start by team up in pairs and stand in front of each other. They agree who starts the game, who plays the mirror and who plays the person. The game begins to the sound of a song chosen by the leader. The person will start to move and the "mirror" will have to follow him/her, immediately repeating the person's movements. When the leader stops the music, they swap places and the person who was the "mirror" becomes the person and vice-versa.

Energizers senpower 26 - Empathy game

Students get into a circle with sheets of paper and coloured pencils in the centre of the room and all students are invited to express, through colour, an emotion or feeling, by using different colours and painting them on the sheet of paper. When they have finished colouring, all the students show the sheet of paper and explain what that colour represents at that moment. If it is something negative, the classmates must voluntarily offer him/her other colours that transmits a positive emotion, that represents something positive. The aim of the game is that everyone feels free to share a feeling and receive peer support if needed.

Energizers senpower 27 - Mathematical quizzes

Engage children using math quizzes. Prepare a few fun and age-appropriate riddles to challenge their number sense and mental calculation skills.

Quiz example:

  • How much is 7 times 6? (Answer: 42)
  • What’s the odd number less than 10 that divided by 3 has remainder 1? (Answer: 7)

Reward the participants who solve the riddles properly with  math-themed stickers or badges.

Energizers senpower 28 - Water cycle

Explain to the kids the process of the water cycle (evaporation, condensation, precipitation) in simple terms.

Play some music and have the kids dance around the play area. When the music stops, call out one of the water cycle stages.

When a stage is called out, the kids must quickly freeze in place, acting out the corresponding stage (e.g., spinning to represent evaporation or forming a group to mimic precipitation).

Continue playing the music and calling out stages intermittently.

Energizers senpower 29 - Calculate in 2 steps

Divide students into 5 groups. It can be done by using playing cards. According to the number of students in the class, find out how many of the 13 ranks in each of the four suits: clubs (♣), diamonds (♦), hearts (♥) and spades (♠) you will need. For example: if there are 20 students, you will need 5 number cards - 5, 6, 7, 8 and 9. Shuffle the cards and let each child draw out their card. Then point out that the numbers of each colour form one team, and that the team formed will have to solve group problems.

If there is an odd number of children in the class (eg. 23), you can have coloured slips of paper for students to pick them up as they enter the classroom. Then, you will need 5 colours with 5 cards/slips of paper for each colour. In such case, some groups will become slightly larger. If you have more children in the class - you can decide whether to increase the number of groups. It’s up to each teacher to decide, according to the size of the classroom and the possibilities to set aside work area for each group.

Set up classroom space for each group to work and put a number in each area – so that the numbers 1, 2, 3, 4, 5 can be easily seen.

The way work places are designed should also give enough space for the movement of students between each of the work places. Place 1 red and 1 green pencil in each working space.

Print Appendix 1 five times. Put each copy in an envelope. Allow each group to draw out 1 envelope. The students do not know that they have the same tasks inside.

Ask each group to go to their table and open the envelope. Give them time to look at the problems, explaining that each group must solve the problems in the row that corresponds to the group number - group 1 solves row 1, etc.

The task includes 2 steps:

1. To perform the arithmetic operations on each row.

The first task requires finding the sum of 2 numbers.

Show this on the board with an example: 4 3 = .........

The second expression requires that you write the numbers from the first expression, swapping their places, and find the sum of the numbers again.

Show this on the board by writing 3 4 = ........

The third task requires subtraction operation to be performed. Each group has to illustrate it using the table below and colour the boxes they used to find the correct answer. Recall the rule starting from the first number in the expression and counting backwards. As many steps are taken as the second number in the expression shows.

Show through the example on the board:

Time for explanation and work: 5 min.

2. Now there is a change of places. 1st group goes to the second group space, 2nd group - to the 3rd, 3rd group - to the 4th, 4th group - to the 5th, and 5th group to the 1st group space.

Each group has to check, if the solution is correct. If it is correct, the group circles the answers in green, but if it finds an error, it writes the correct answer in red.

Working time: 3 min.

Energizers senpower 30 - Find the figure

Option 1

Divide the class into several groups.

Each group gets 1 set of the shapes and explanatory texts (Annex 1) - cut out separately each statement that describes the shape.

The task of each group is to match the statements with the images of the shapes.

When the groups are ready, check if the task was competed correctly.

This exercise serves both to energize the students at the beginning of the lesson and as a transition to the topic of the lesson.

Working time – 8 min.

Option 2

Rearrange the tables (or desks) so that students can move freely around the room.

Place the images from Annex 1 in the corners of the classroom.

Allow each child to pick up a card with a description of a geometric figure. The task is to get as quickly as possible to the place with the geometric figure that corresponds to the description of the card.

This exercise serves both to energize the students at the beginning of the lesson and as a transition to the topic of the lesson.

Working time – 3 min.

Energizers senpower 31 - Movement calculations

Calculate moving

The teacher has pre-printed and laminated the cards from Appendix 9 – Energizing exercise

The teacher says:

-    We're going to play a game. I will tell you riddles and I will pull out one of my cards  which have symbols for squatting, jumping and spinning. The answer to the riddle will determine the number of moves.

-    How many units are obtained if I subtract 1 unit from 1 ten?

-    How many tens are obtained if 5 units are added to 5 units?

-    How many units do you get if you add 5 more units to 5 units?

-    How many units are obtained if I subtract 10 units from 1 ten?

Energizers senpower 32 - Blocks game

Blocks game

Use Appendix 1 to prepare the working materials by printing as many copies as you will need.

Divide the students into pairs. Give each pair of students 9 blocks of tens and 9 blocks of units in an opaque envelope.

One of the students shakes the envelope, pokes in without looking, and takes out 7 blocks. The other one takes the rest. Each one writes down the number that they have drawn, and then the students combine the two drawn numbers to find out the sum. The students change the order and repeat the activity.

After that, ask those who wish to write down the numbers and the sum on the white board. Discuss the results with the whole class.

ASK: Why do all groups always get the sum of 99? (the blocks in the envelopes make 99). Why do we have so many different ways to sum numbers? (the students drew different combinations from the tens and from the units blocks). Who has more blocks - the one who has drawn 7 first or the one who takes the rest? (the one who takes the rest). Who gets the bigger number? Does the one with more blocks always have a bigger number? If the students confirm this, challenge them to come up with a way for a person to have more blocks, but a smaller number. If they don't answer, ASK: How is it possible that the person with more blocks have a smaller number? (one block of tens has more units than one block of units, respectively, the smaller number of blocks of tens can actually be a larger number than a larger number of units as individual blocks. Conclusion - the number of blocks does not tell us the number of units) .

Time – 5 min.

Energizers senpower 33 - Broken telephone
  1. Divide the students in 2 groups and ask each group to stand in a line so that every students faces the back of the person in front of him/her.
  2. The last person in the line thinks of a sequence of actions, e.g. patting your head, turning round and rubbing your tummy, and signals to the person in front of him/her to turn around, and performs the sequence of actions.  
  3. The student who watched the sequence of actions has the task to remember it, and then, turns around, signals to the person in front of him/her to turn towards him/her and performs the same sequence of actions. 
  4. The game continues until the first person in the line sees the actions.
  5.  Finally, the first person in the line shows the sequence to the group. The movements may have changed as they have been passed along, providing a fun laugh for all!  

The activity can be repeated several times changing the last person in the line who starts the game.

Energizers senpower 34 - Triangle or circle

The whole class participates in the game. All students face the teacher.

Step 1: The teacher says circle and students raise their hands up and make a big circle above their heads.

Step 2: The teacher says triangle and students make a "roof" over their heads in the shape of a triangle.

Step 3: The teacher gradually increases the tempo and repeats randomly the two words circle and triangle. Anyone who does not make the named figure is out of the game. The activity continues until there are only 2 or 3 children left playing, or until the teacher decides to end the activity.

Energizers senpower 35 - Angles

Students get up from their seats and stand next to their desks/tables. The teacher explains to them that he/she is going to use his arms as the arms of an angle, and they must perform the corresponding action depending on how he places his arms. When:

• he/she stretches one arm out to the side parallel to the floor, at shoulder level, and raises the other up, students must lean back;

• he/she raises arms up and makes a "roof" above his/her head, students must lean forward;

• one of his/her hands points down to the floor and the other one points to the floor to the side, close to the body, students should squat.

If there is time, the activity continues with a student taking the teacher's place.

Energizers senpower 36 - Balloon game

No. of participants: All the students in a class

Organisation: 2 groups sit on the floor in a row behind each other.

Material: 2 balloons.  

Description

Organise two rows side by side, with the students sitting one behind the other. The teacher gives a balloon to the first person in each row who, on the teacher's signal, must pass it on to the next person, without anyone dropping it. When the balloon reaches the last member, he comes to the front of the queue and continues along the line.  Whenever someone loses the balloon, the balloon goes back to the beginning, i.e. to the first person.

Energizers senpower 37 - Fruit game

Location: Classroom/Interior.

No. of participants: All the students in a class.

Organisation: Students stand in a circle.

The names of three fruits are chosen: pear, apple and banana;

Each fruit is associated with a gesture: pear - clap your hands; apple - jump backwards; banana - hold up your hands.

The teacher names the fruit randomly, which the students have to match with the correct gesture. Whenever a student makes a mistake, they leave the game. The pace at which the fruit is named can be increased in order to increase the difficulty of the game.

Energizers senpower 38 - Opposite game

Location: Classroom

No. of participants:  All students in a class

Organisation: Students stand in a circle.

Materials: None

Game description:

The students are lined up side by side. The teacher starts by giving an order, e.g. one step forwards, but the aim of the game is to do the opposite, so the students must step backwards, raise their right hand while their left hand is raised, ... The orders should be anything that can be done the other way round.

The participants must do exactly the opposite, whoever makes a mistake and doesn't do the opposite is out of the game.

Energizers senpower 39 - Numbers in pairs

Location: Classroom

No. of participants:  All the students in a class.

Organisation: All the students in the class organised in pairs.

Materials: None

Game description:

The students stand with their backs to their partner, back to back. At the teacher's signal, they jump up and face their partner, each raising as many fingers as they have thought of. When they both think of the same number and then hold up the same number of fingers, they win. 

Energizers senpower 40 - I went to the market

Location: Classroom/Interior

No. of participants:  All students

Organisation: Students in a circle in a seated position

Game description:

The teacher starts by saying "I went to the market and bought some corn". Then the next student has to repeat the sentence and add new information, for example: "I went to the market and bought some corn and some apples" and so on. Once again, this is an activity that trains children's memory, as the aim is not to forget the sequence of purchases.

Energizers senpower 41 - Odd one out

Location: Classroom/Interior

No. of participants:  All students

Organisation: Students are seated in a circle

Game description:

The teacher explains that he or she is going to say four words ( they can be related to the topic), and their task is to find out which one doesn't go together and which ones are similar considering a specific characteristic.

Examples:

- Which is the odd one out?

- Circle, ball, cube, triangle (answer: ball)

- Hour, minute, house, second (answer: house)

- Left, front, first, right (answer: first)

Energizers senpower 42 - My aunt went to ...

Location: Classroom

No. of participants:  All students

Organisation: Students sitting in a circle

Description of the game:

The first person starts "My aunt went to Spain and bought, for example, a hat" (or any object). The next person says "My aunt went to Spain and bought a hat and a suitcase" (i.e. repeats what the previous person said and adds their own object) and so on. Whoever gets it wrong leaves the game. 

To increase the difficulty: Each object can be ordered in alphabetical order.

A - Apple; B – Ball;  C- Car; D - Cards; H-Hat; S- Shopping Bag, …

Energizers senpower 43 - Fishnet game

Divide the class into two groups. One group, arranged in a circle, forms the fishing net. The remaining students are the little fish and will move freely around the room. The students in the net agree on a number without the little fish hearing them. They form a circle by holding hands and start counting in series (1,2,3...) until they reach the agreed number. The little fish know they can start moving when they see the wheel formed. When they reach the agreed number, they bend down and pick up the fish that remain inside the circle.

This exercise serves both to energise the students at the start of the lesson and as a transition to the lesson's theme.

Energizers senpower 44 - Mimicking animals

The teacher instructs students to mimic the movements of animals in the following sequence: fox, dog, hare, hedgehog.

Energizers senpower 45 - The dinosaur energizer

Ask each student to think of their favourite dinosaur and be ready to share it with the class. Then, organize the students in a straight line, standing side by side. Now, each student should imitate the dinosaur movement following these steps:

  1. One by one, each student will announce their favourite dinosaur.

  2. After announcing, the student will move across the room, imitating the locomotion of their chosen dinosaur (e.g., stomping like a T-Rex, flying like a Pterodactyl, or lumbering like a Brachiosaurus).

  3. The rest of the students will observe carefully the different movements.

After everyone has had a turn, gather the students for a brief discussion. Ask them to share what they noticed about the different types of dinosaur movements. Discuss how the structure and size of each dinosaur might have influenced its way of moving.

As an alternative:

If the school has a large enough sandpit, a short activity could be organised to make students realise the relationship between the way humans move and the marks registered on the ground. This activity would consist of asking students to freely produce footprints in the sand as a result of walking (A) or running (B) (Figure 3). 

Figure 3. Walking and running footprints.

The aim of this exploration would be to realise that the higher the speed of movement, the further apart the footprints tend to be arranged on the track, as well as more aligned (B), as opposed to walking, where consecutive footprints tend to be closer together and more side by side (A).

Some engaging questions are:

  • What happens to our footprints when we walk slowly? Do they get closer or further apart?

  • And when we start running, does the distance between our footprints increase or decrease?

At this stage the teacher can organise a more structured demonstration, with a chosen student, to compare the two situations.

Energizers senpower 46 - Movement

Ask the students to lie down on the floor (on their backs or tummies) and tell them to demonstrate the sliding movement.

Figure 1. Illustration of the sliding movement


 

Some questions for discussion:

  • How would you describe the slide?

  • What changes when you slide?

Now, ask the children to lie down on the floor again and give their interpretation of the flipping movement (in a turn the pupils move from back to tummy or from tummy to back).

Figure 2. Illustration of the flipping movement

Some questions for discussion:

  • How would you describe the flip?

  • What changes when you flip?

Finally, ask the pupils to lie down on the floor and demonstrate the turning movement.

Figure 3. Illustration of the turning movement

Some questions for discussion:

  • If turning your back to your tummy is a flip and not a turn, what is turning like?

  • What changes and what remains the same when you turn?

  • Is the body pointing in the same direction before and after turning?

Students should be encouraged to use their own words to describe and characterize the different movements.

Moves like sliding, flipping and turning constitute rigid motion. They are motions that do not distort shape. Picking something up and moving it around for instance is a rigid motion, but stretching or warping it is not. These intuitive experiments are an excellent way to introduce more advanced geometric concepts, such as translation, reflection and rotation, as fundamental types of isometric transformations. In this lesson, we shall focus on the idea of rotation.

Energizers senpower 47 - Pig Game

“Pig game” is a simple dice game which in its basic form is playable with just a single dice. You win by being the first player to achieve a certain number of points.

To play you'll need 2 to 10 players, one 6-sided dice, and a pencil and some paper for keeping score.

The teacher organizes the class into four or five groups, each acting as a team. Each group rolls a dice to determine the order of play, with the highest number of points going first, followed by the next highest, and so on. If possible, use a large dice made from soft material so the activity can take place with students standing and moving.

The first team rolls the dice and scores the number of points shown, provided they do not roll a 1. If the team rolls a 1, their turn ends, and they lose all the points accumulated during that turn, passing the die to the next team. Team members must decide collectively whether to continue rolling and risk rolling a 1 (and losing their points) or end their turn and keep the points earned.

Scores can be recorded on the whiteboard or blackboard. Play continues from team to team until a winner is determined. The first team to accumulate 50 or more points wins the game.

Energizers senpower 48 - Movement

Part I

The teacher asks the students to form pairs and gives each pair a piece of paper and a pencil. Then, each student should trace their right footprint on the paper and write their name next to it. Afterward, they should observe both footprints and identify which one is larger.

Part II

Teacher says to the students: “So today, let’s walk, run, or jump with energy!”. Students should move around, walking, running or jumping at the sound of a previous music chosen by the teacher.

Relaxing Exercises senpower 1 - Guided fantasy

Students are asked to close their eyes (if comfortable) and, with the guidance of the facilitator, slowly imagine a scene of the past or future event. More and more details are used to describe the event with all senses and thoughts. A suggested brief script could be à Begin by breathing slowly and deeply… Think of yourself in a place where you feel relaxed and at ease… Create all the details in your mind, what do you see… what the sounds are like, the smells and colors of this special place… Are there any people …?

Rossman, 2016

Relaxing Exercises senpower 2 - Progressive muscle relaxation

To release tension from head to toe, students are asked to close their eyes (if comfortable) and focus on tensing and relaxing each muscle group for two to three seconds each. The teacher guides the students; he/she asks them to start with the feet and toes, then move up to the knees, thighs, rumps, chest, arms, hands, neck, jaw, and eyes—all while maintaining deep, slow breaths.

Relaxing Exercises senpower 3 - Guided breathing

Teacher asks the students to close their eyes (if comfortable), inhale for a count of four, then exhale for a count of four (all through the nose, which adds a natural resistance to the breath). Then, with one hand on the chest and the other on the belly, the students can take a deep breath in through the nose and exhale through the mouth, ensuring this way that the diaphragm (not the chest) inflates with enough air to create a stretch in the lungs

Relaxing Exercises senpower 4 - Visualization using color/soothing sound

Facilitator asks the students to imagine a favorite color that makes them feel peaceful and safe. They keep their imagine taking in that color with each breath and sending it throughout their entire body as they exhale. They continue until they visualize being filled with their special, relaxing color. The same exercise can be performed using soothing sound or aroma. Also, it is more effective if relaxing music is used.

Relaxing Exercises senpower 6 - Bee breathing

The teacher instructs the students to get in a comfortable position to practice bee breathing. They have to imagine that they are sitting on a leaf or a flower petal, to sit straight and allow the leaf or petal to gently support them.

The teacher gives students the following instructions:

Breathe in, allowing the air to just gently come in through your nose, filling up your lungs.

As you breathe out, buzz like a bee. See how long your buzz can last. See how far your bee is going to fly before sitting down and resting again. Buzz. Buzz. Buzz.

On the next breath, see if your bee can fly with a loud, strong buzz.

On the next breath, see if your bee can fly with a soft buzz.

When the exercise is finished, the teacher gives time for a short discussion:

Does it feel different with a strong or a soft buzz?

How does your body feel?

Optional (use if time allows): After breathing practice, draw a picture of a bumblebee and the leaf or flower that you were “sitting on” in your imagination. This picture can be used as a relaxation practice reminder. When you see the picture, practice being like a Bee on a leaf and practice a Bee breath.

Relaxing Exercises senpower 7 - Strong as a tree

All students spread out in the room. With their feet firmly planted on the ground, they pretend they are trees that are slowly swaying back and forth with a breeze. The movements become stronger as a storm approaches. The students try to make their movements as strong as possible, but remember to keep their feet on the ground. Slowly the wind dies down and the trees can rest.

Relaxing Exercises senpower 9 - Lion's breath

Lion’s breath is a playful way to release and relax into more peaceful feelings. The trainer tells students that they are going to do a breath called the lion’s breath in order to let go of feelings or thoughts we no longer want. This breath is very helpful in getting those ideas out of us and pushing them far away.

Instructions

  • Imagine that you are a mighty lion. You have a giant roar!
  • Sit on your heels and sit up tall like a mighty, proud, lion. Get ready to let your roar go!
  • Think of a feeling or a thought that you would like to let go. Squeeze your hands into fists, holding tight and thinking of that feeling or thought.
  • Take a deep breath in and let your roar out, stick out your tongue at the same, stretch your arms out wide in front of you and open your hands wide, roaring out the feeling or thought and letting it go.
    • Repeat.

Relaxing Exercises senpower 13 - Body massage

The students stand in a circle: they need to follow all the movement the teacher does and massage themselves. The teacher starts to massage different parts of his/her body, starting from the head till the feet (it’s better if they take off their shoes). The teacher explains how the massage needs to be done, if delicate or more energetic.

Optional: The teacher can also ask to the students to massage another classmate.

Relaxing Exercises senpower 14 - Give me your energy

The students stand in a circle. The teacher starts, pretending he/she is holding a ball on the hands and passing it to the student on his/her right; this one do the same, until the ball comes back to the teacher. The ball needs to be passed in a gentle way, as it is very precious. At the second round, the teacher passes the ball to students in another side of the circle, making a gesture and a noise. The students will do the same until everyone will have touched the ball at least once.  The ball can be passed in any way (in form of kick, kiss…), pretending it becomes bigger or smaller depending on the will of the students. 

Relaxing Exercises senpower 15 - Moving like a toy

The teacher uses a magic word to change the students into many string-loaded (wind-up) toys. At the teacher’s signal, the toys start to move across the class, as many robots, to get their sits. They have to move more quickly at the beginning and then gradually more and more slowly, because their charge is finishing. Some of them will be frozen in the middle of the room, and the teacher has to give their cranks one more turn to help them reach their seats

Relaxing Exercises senpower 16 - Pass the face

It is like the game "telephone" but instead of passing a word or sentence around the group, participants pass a facial expression.
The group forms a circle with everyone having their eyes closed, except the person who is passing the "face" in the first place. The passer will tap the shoulder of the person next to her/him, that person will open her/his eyes to receive the face. She/He will then tap the shoulder of the person next to her/him and pass the face along. Once participants have passed the face they may keep their eyes open to watch it move around the group. At the end, the original passer receives the face from the last person in the group and then shows what the original face was.

Relaxing Exercises senpower 17 - Circle massage

The group forms a circle and faces one direction. Each participant places his/her hands on the shoulders of the person in front of her/him. Each person then gives the person who is in front a shoulder massage. The person being massaged can give a feedback. After a few minutes, the group turns the other way so that the person who has been making the massage is then receiving it in return.

Relaxing Exercises senpower 18 - Making room

Participants are asked to raise their arms with palms facing up, imagining that they are pushing up the ceiling and are asked do a lot of strength in that direction to increase the space of the room where they are. Then they are asked to turn the arms down with palms facing down thinking that they are pushing down the floor. They are asked to push away the walls turning their left arm and palm to the wall on their left and their right arm and palm to the wall that’s on their right.

Relaxing Exercises senpower 19 - Massage ball

One ball is given to each participant and, following the rhythm of a soft music, they place the ball between their back and a wall. They bend their knees slightly to relax the legs and better place their back. Then they move their body from top to bottom and from right to left and vice versa, moving the ball around their back. When making movements of their body, they will notice some more tense (and sometimes painful) spots. When they notice this they should stop and stay quiet keeping their back against the wall, making the desired pressure and holding for a while.

Variation: Do not use the wall. Participants work in pairs and one holds 1 or 2 balls in their hands and makes the massage to the other and then they switch.

Relaxing Exercises senpower 20 - Holding legs

Participants work in pairs. And you can put a quiet and relaxing music (or sounds like water falling down, sea waves, etc.). 

Half of the participants are asked to lie down face up, eyes closed, with their left leg extended on the floor and their right leg elevated. Another participant stands up and loops a towel around the heel of the other’s right foot and holds the ends of the towel in his/her hands, and makes soft and gentle movements (upwards and downwards, and sidewards) while the other totally relaxes his/her leg. Then they repeat the same process with the left leg. Then the participants switch roles.

Relaxing Exercises senpower 23 - Guess who? Draw your partner

With the Avatars distributed randomly on a table, the students are invited to get one of their classmates' Avatars, which they have to complete, trying to understand whose half of the Avatar they have to complete and silently draw the missing half to the sound of a calm song chosen by the leader.  As the students finish, they go to a board and place the completed Avatar with reusable, malleable white adhesive putty. The whole class observe and the challenge is to try to guess to whom the avatars belong to.

Relaxing Exercises senpower 24 - The Pot of Calmeness

We call "the pot of calmness" to a jar in which we put water, liquid silicone to give density to the content and glitter of different colours.

The construction of the jars is done in advance by the students and they can remain in the classroom to be used at other times when the call for relaxation and calmness is necessary. 

Each student gets his/her jar, shakes it and observes the movement.  Afterwards, the group talks about what is observed:  that the glitter represents the students’ emotions that they shake and stir until they are calmed down. This activity is ideal for fostering reflection.

The simple act of watching the glitter moving slowly will help the students to relax.

Relaxing Exercises senpower 25 - Body Numbers

Students are instructed to lie on the floor with the task to form numbers or numerical expressions with their body positions. They can do the activity either individually or in groups of two or three to combine their body positions to form numbers or numerical expressions.

Relaxing Exercises senpower 29 - Rhythmic game

A Rhythm Game

The class is divided into three groups. The instruction for the first group is to use clapping, the second to stomp with their feet, and the third to use hip tapping. The teacher sets a rhythm by explaining that when there is a pause, he/she will signal with a pointer in front of the mouth for silence. Different rhythms can be played by alternating the three groups under the "conduct" of the teacher. Onomatopoeic words can also be used, for example: clap, clap, thump, thump, bang, bang.

 In the worksheet Appendix 7, 4 lines of different rhythms are indicated. Some or all of them can be performed on teacher’s decision.

Relaxing Exercises senpower 30 - Grouping

Grouping of units and tens

Remind the children of the grouping rules:

10 units make 1 ten.

Illustrate the ratio of 1 to 10 with the picture as well (you can draw it on the board or show it on a slide), asking the students: How many units are in the block? And how many tens are there in the column?

We can present number 10 either as 1 column of 10 squares or as one block.

Tell the students that the tens block (point at the first block) is drawn very slowly and to make it easier for us, we sometimes draw it as one long block (point at the second block).

Relaxing Exercises senpower 31 - Triangle of friendship

Students work in pairs to draw a triangle to represent their friendship. Before starting the work, the teacher demonstrates the steps with one of the children. The two persons in the pair place their hands down with the palms facing the surface of the paper sheet; student 1 uses his/her right hand, and student 2 uses his/her left hand.  They join the tips of the thumbs and the forefingers of the left hand of one of the pair with the tips of their thumbs and forefingers and outline the shape of the triangle between the fingers. After that, they can draw eyes, a nose, a mouth and whatever they want to, in order to design a personal symbol of their relationship.

Introduction

A large part of our daily life is related to mathematics. Knowing numbers is of great importance, but it is especially important to be able to perform calculations with them. Imagine you want to buy a few things, but you are not sure if the money you have will be enough. If you know the total cost of the things you want, you will be able to judge whether or not you have enough money to buy what you want. This is where addition comes to the help you. And if you want to check if the change they gave you back in the shop was correctly calculated? Well, that's when subtraction comes to help. We use addition and subtraction of numbers in many activities in life - shopping, in various games, when arranging the table for breakfast, lunch or dinner, and many others. In this lesson, you will learn what it means to add up and take away numbers, how these operations are performed and how they are to be recorded.

Teaching and learning methods

Learning in small steps

Break instructions down into smaller parts

Use technology and visualization

Provide real-life examples

Collaborative learning

Countable manipulatives

Interdisciplinary connections

Home economics: buying goods, paying with money, working with money

Mother tongue: communication skills

Resource teacher or other specialists activities

Almost all the steps of the lesson are comprehensible to most of the students with special needs who have well-preserved cognitive abilities. The lesson does not comprise a lot of text and long instructions to make it difficult for the target students to understand and follow the work flow.

The role of the special needs teacher/teacher's assistant is to help target group students if they are not able to cope with some of the tasks and steps.

New vocabulary

Addition, Subtraction, plus and minus signs

Work Flow
  1. Start the lesson by revising students' knowledge of numbers 1 and 2. To do so, use the number and object cards from Handout 1. Distribute one set to each student. Ask students to first lay out the two number cards in front of them. Then ask them to match the remaining cards into two groups considering the number of objects depicted on them. (5 min)
  2. Continue with Handout 2. Distribute the set of three cards from the handout to each student. Ask students to find and separate the card with the kittens. First task them to identify and write down the number of animals to the left and right of the blank square. Then ask them to compare the written numbers by drawing one of the signs minor, major  or equal.  Repeat these activities with the remaining two cards. (5 min)
  3. Describe the following situation to the students, and if possible, visualize it by providing a box of pencils:

There are some pencils in a box. If you want to find out exactly how many there are, you need to count them. Now, imagine that you find 2 more pencils in your bag and decide to add them up to the ones in the box. In this case the number of pencils will increase - the new pencils will be added to the ones in the box.

What happens if you decide to give some of the pencils from the box to a friend? You will take them out of the box, and, as a result, there will be fewer pencils left in the box.

To represent the actions of adding up or taking away items, we can use two arithmetic operations - addition and subtraction. (3 min)

  1. Make a connection between numbers 1 and 2 which students already know, and the newly introduced arithmetic operations we can perform with them - addition and subtraction.

Ask each student to prepare 2 pencils.

Show the first slides of the presentation, which demonstrates adding up 1 element to a group that already contains 1 element. At each step of the demonstration, ask questions.

Examples:

  • Ask students to place 1 pencil in front of them and ask the question: How many the pencils are there in front of you?
  • Have students place 1 more pencil in front of them and ask: How many pencils did you add?
  • Ask students to determine the total number and ask the question: How many pencils do you have all together now?
  • Summarize that when we add up another object to one object, we get a total of two objects.
  • Present the way of recording the performed actions. Read the entry 1 1 = 2 and associate this equality with the arithmetic operation addition. Conclude that when 1 item is added to another set of 1 item, the total of the operation is 2 items.

Next step: use the second part of the presentation and introduce the operation of taking away 1 element from a set that contains 2 elements. At each step of the demonstration, ask questions.

Examples:

  • Have students place 2 pencils in front of them - How many are the pencils?
  • Have them remove 1 of the pencils - How many pencils did you take away?
  • Ask students to count how many pencils they have in front of them - How many pencils are left?
  • Summarize that when we have two objects and take away one of them, the result is that we have one object left.
  • Present the way of recording the performed actions.  Read the entry 2 – 1 = 1 and associate this equality with the arithmetic operation subtraction. Conclude that when we take away 1 object from a set of 2 objects, we have 1 object left.

It is important to make sure students understand that when we add up items, the resulting number is greater than any of the numbers we add up, whereas when we subtract, we result is a number which is smaller than the one we subtracted from. (10 min)

  1. Distribute Handout 4 to each student. The tasks are to be completed one after the other.
  • Task 1: Ask students to determine which operation (addition or subtraction) is represented. Remind them that when we add up, we perform the operation addition and use the plus sign to record it. When we take away, we perform  the operation subtraction and use the minus sign. The task is to write a  or a sign on a post-it note and stick it on each image.
  • Task 2: Write the digit that shows the number of objects you see in the pictures.

To do the first example of task 3 as a hands on activity, instruct students to make 1 small ball of plasticine for each hat they see on the left side of the equals sign and then, put all balls together – this is the result of the operation addition . Have students solve the addition problem by filling in the blanks with numbers.

For the second example in task 3, as a hands on activity, ask students to use the previously made small balls to demonstrate a subtraction action - 'taking away' an object can be expressed by crushing one of the balls  with a thumb. Ask them how many whole plasticine balls are left after crushing one of them. Have students solve the subtraction problem by filling in the blanks with numbers.

  • Task 4: Identify the missing sign and write it in the space.

You could give the students an extra task to design an addition or subtraction problem with  numbers 1 and 2 and the plus, minus and equal signs. To do so, you have to prepare in advance small paper cards with the numbers and the three signs. (20 min)

  1. Simulation game of shopping: Divide the class into teams of four. Organize asimulation of shopping in the market making use of the small objects you have prepared (dice, colored sticks, cardboard plates and cups, etc.). Distribute them among the teams. Give each team small pieces of paper to write the price of each item they offer at the market. The price of an item is either 1 or 2 euros. Explain that these are not real prices, they are just for the game. In real life, prices are different, but the idea of calculating the total price when doing some shopping is the same. Distribute the paper coins among the teams. One of the participants in each team is to step in the shoes of the seller/cashier.

Task 1: Each student is expected to choose which two items which cost 1 euro he/she wants to buy. After making their choice, the students must pay the cashier for their purchase, using the 1 euro or 2 euro paper coins.

Task 2: Everyone should choose only one item with a price of 2 euro and make a choice how to pay for it – with two coins of 1 euro or with one coin of 2 euros.

Task 3: Each student should choose an item with a price of 1 euro and pay for it with a coin of 2 euros, calculating how much change he/she should receive. The cashier gives back the change. (15 min)

6. Finish the lesson with e-games: Students play the games on their mobile devices or the teacher opens a game on the screen and volunteer students take turns to come to the front and play. (10 min)

Reflection

Activity 1. Ask the following questions:

1. What is the most useful thing you learned today?

2. Which activity in the lesson did you like most?

• The energizing exercise Find another place.

• The addition and subtraction song.

• The shopping game.

• The relaxing exercise Mountain Range.

Activity 2. Give each student a face card. Ask them to draw a face with an emotion that best presents how they felt during the lesson using the following colours:

• in green, if they are satisfied with what they have learned and with their work;

• in yellow, if they are not particularly satisfied;

• in red if they are not satisfied.

Set a time limit and after that all students are asked to hold up their emotion cards. The teacher counts the number of green, yellow and red faces and reports to the class. If you have enough time, student representatives of the three groups could share the reasons for their choice of emotion. (5 min)

Notes

If you know a song about addition and subtraction in the students' native language, you can play it to the class as an introduction.

Energizers senpower     23 - Emotions Games

Materials required:

  • Medium size ball
  • 5 A5 size cards with the faces of the emotions.

Move the tables and chairs around the classroom, so the students can sit in a circle.

The game begins with a ball being thrown to a student, at this point the leader who has got the 5 cards (one for each emotion), raises a card; the child who has received the ball must talk about a situation that triggers the emotion that the leader has raised. The ball is then thrown to another classmate and so on until all the students have received the ball and all of them have had a chance to talk about an emotion.

The ball can only be thrown once to each student.

The game ends when all students have received and thrown the ball and all of them have spoken about an emotion.

Relaxing Exercises senpower     21 - How do I feel today?

The proposal is that each child should draw his or her face according to the emotion he or she is feeling at that moment: happiness, sadness, anger, fear and calmness.

Objectives

In the end of the lesson students should be able to:

- organise and present information in a clear way;

- represent a data set through pictogram;

- represent a data set by means of a dot graph;

- interpret the data in the pictogram and graph.

Preparation

Material:

  • 5 Empty canning jars with a hole in the lid;
  • Coloured wool: green, red, black, blue, and yellow;
  • Five plastic writing pens - one green, one blue, one yellow, one red and one black;
  • Felt pens, or crayons, or paint to draw/paint the emotions;
  • Glue;
  • A4 sheets;
  • A2 sheet, for double entry board, size;
  • A2 sheet, for table A3 sheet white plasticized;
  • Velcro;
  • Transparent sticky paper;
  • Tasks on printed A4 sheets;
  • White reusable adhesive putty;
  • Computer;
  • Video projector;

Every day before the end of the lesson, the teacher asks students how their day was.  Each student assesses him/herself and refers to the emotion he/she feels by taking a woollen thread from the jar of the corresponding emotion. Each child, with the teacher or a classmate’s help, ties it to his/her wrist the woollen thread. Then the children go to the Emotions Picture Board - Appendix 1 (printed in A2 size and laminated with transparent adhesive paper, see appendix 1), which is attached to the students' height with malleable and reusable adhesive mass, on a wall in the classroom and mark with a pen, which allows them to write on plasticized material, a little ball, matching the day of the week and the emotion referred to.  The board has a double entry, so that the days of the week are shown horizontally and the emotions are shown vertically.

This procedure is kept throughout the week, so that on the last day or at the beginning of the following week the recorded data can be evaluated.

Preparing the lesson

Begin by moving the necessary tables and chairs out of the classroom to free up the centre of the room so that students can sit in a circle.

After the game has been run, return the hijacked tables and chairs to their places to continue the lesson plan.

Introduction

In our daily lives we are in constantly contacting with statistical information, which are presented in different forms. Therefore, it is an essential subject for everyone, as it is necessary to know how to analyse and interpret the information.

Hence the need to learn to explore collectively the construction of a table, pictograms and graphs, using a symbol to represent each piece of data (one-to-one correspondence).

Learning to ask a question and collecting data related to that question, to organise the data collected and finally to analyse and interpret the results in an organised way.

Teaching and learning methods

Learning based on concrete questions/situations and proximity to the students.

Learning through an effective manipulation of material, making awareness of what is being learned easier.

Cooperative and collaborative learning in small groups and in pairs.

New technologies as a way of learning/consolidating content and assessing learning.

Interdisciplinary connections

Portuguese – Language comprehension and production;

Social Studies - Factors that contribute to individual psychological well-being;

Artistic Education - Visual Arts.

Citizenship and Development - According to the citizenship education students need  to know how to identify, recognise, understand and communicate their emotions because this is important for the creation the social relationship process.

Resource teacher or other specialists activities

All steps of the topic development must be understandable for SEN students with cognitive abilities. The lesson does not include long written explanations. The role of the support or special education teacher is to help students in the target group if they are unable to complete any of the tasks or steps, or feel disorientated in understanding something that may be required.

New vocabulary

Tables; pictograms and graphs.

Work Flow

1st Step:

On the last day of the week, the teacher invites two students at random, or at her discretion, to go to the emotion board posted on the wall and asks them to count the little balls/dots/rings made of wollen that correspond to the various emotions, with the help of the whole class. (See Appendix 1)

2nd Step

Fill in the table size A2 (which follows in Appendix 2).

After completing the previous task, a pupil with the help of the whole class, draws vertical lines for each emotion on the table also posted on the wall of the classroom, preferably next to the emotion board.                                                                                            

3rd Step

Record the emotions on a pictogram, which is a type of chart that uses pictures or symbols to represent data. The pictogram also in A3 size (which is attached in Appendix 3). It should be made on white laminated paper, to be hung on the wall next to the chart.

Collectively with the whole class, transfer the data from the table to the pictogram, lining up cardboard circles (representing the different emotions) with Velcro over each emotion at the bottom of the pictogram. Once the pictogram is completed, the class answers the following questions:

- What was the most recorded emotion or emotions/s?

- Which emotion or emotions registered the least?

- Was there an emotion or emotions that was never registered?

4th Step

5 groups are formed - each group corresponds to an emotion; with a felt-tip pen in the colour of the emotion assigned and an A4 sheet of paper with a chart of dots to be filled in, with the days of the week at the bottom (see Appendix 4),  the groups are instructed to place the number of dots corresponding to the emotion assigned on each day of the week. Students are expected to answer the following questions:

  • Which day of the week most students register each emotion (the answer is given group by group according to the emotion each group works on).
  • Which day of the week the fewest students register each emotion (the answer is given group by group according to the emotion each group works on).
  • Which emotion was the most registered during the week?
  • Were there any emotions not recorded on any day/s of the week?

5th Step:

One member of each group will put their chart side by side on a wall or board that is visible to all students. Ask the question: What was the most registered emotion during the week?

By looking at the graphs next to each other, the students can help each other to come up with an answer. Then, and to confirm, they can all count the total number of points recorded for each day of the week.

6th Step:

Evaluation through a game created in WordWall.

Developed by Antalya Directorate Of Education
Grade 1
Duration 60
Energizers senpower     1 - Break the Circle

The teacher assigns randomly a number to each student, depending on the group size, i.e. for 20 students, numbers 1-4 are ok, so each group has 5 people (groups could be synthesized by the students with the same number, i.e. all having been assigned number ‘1’ or by students where each one has his/her own unique number 1-4; similarly and more fun is grouping by ingredient for a Greek salad, where every student is i.e. ‘tomato’, ‘cucumber’, ‘onion’, ‘oregano’, etc.) Once the groups have been formed, they make  circles and the teacher randomly picks a number (or an ingredient) to step out of the circle and try to break in, while the others remaining are instructed to not let go of their hands no matter what. This can be repeated once more with another number stepping out.

Relaxing Exercises senpower     5 - Use a word that describes their feelings/thoughts

Students are asked to close their eyes (if comfortable) for a minute and think of a word that describes their feelings/thoughts after finishing the resource. Then the students open their eyes and one by one say their word to the classroom

Objectives

Students will learn to:

·       determine the quantity of objects in a collection of up to 20 items;

·       represent this number in numeric form.

Preparation

Ingredients:

Chickpeas, beads, pasta, or counting sticks

Cards with numbers up to 1-20 (see Annex 1)

Objects cards representing numbers between 1-10 (see Annex 2)

Reusable glue or tape

Equipment:

Laptop and projector

Tablets for the assessment (optional)

Classroom settings

Tables (or desks) arranged to allow students to move freely around the room

Instructions:

Print and cut out the number cards 1-20 (Annex 1) and paste/hang/place on wall.

Print and cut the cards with objects representing numbers 1-10 (Annex 2).

Make available counting sticks, beads, pasta, or other materials (30 pieces for each student).

Introduction

Welcome, young mathematicians! Today, we're diving into the world of numbers and learning to count up to 20. Are you ready? Let's go!

Teaching and learning methods

Learning in Small Steps: Counting and number concepts are introduced in small, sequential steps, tailored to cater to each learner's individual pace and unique learning needs.

Breaking Down Instructions into Smaller Parts: Instructions are presented in simple language, broken down into manageable parts to ensure clarity and understanding for all learners.

Using Multi-Sensory Tools: Multi-sensory tools, such as tactile materials, auditory cues, and visuals, are incorporated to accommodate diverse learning styles, enabling active participation and comprehension.

Adaptive Technology: The learning experience is made more inclusive and accessible by utilizing adaptive technology and assistive devices, providing additional support and flexibility.

Real-Life Examples with Personal Relevance: Numerical concepts are linked to real-life situations that hold personal relevance for each learner, facilitating better understanding and practical application.

Active Participation in a Supportive Environment: A nurturing and supportive environment fosters active participation, building confidence and a positive learning experience for all learners.

Individualized Question-Answer Interactions: Learners benefit from individualized attention, with opportunities to ask questions and engage in discussions tailored to their specific learning needs.

Collaborative Learning: Encouraging collaborative activities and group work promotes social interaction and mutual support, allowing learners to learn from one another in an inclusive setting.

Interdisciplinary connections
Resource teacher or other specialists activities

In this lesson, the steps are designed to be easily understandable for most learners with special needs who have well-preserved cognitive abilities. The lesson avoids using lengthy written explanations and complex instructions (TGSt), which can be challenging for the pupils in the target group.

The teacher or assistant teacher with special needs plays a crucial role in providing support to the TGSt. If some tasks or steps become difficult for these learners, the teacher or assistant teacher is there to assist and guide them.

During the practice of naming numbers, the teacher with special needs can sit alongside students who have learning difficulties and repeat the names clearly. While counting, the emphasis is placed on realizing that the last number spoken represents the quantity of objects. This approach ensures that all learners, including those with special needs, receive the necessary support and encouragement to succeed in the lesson. By fostering a supportive and inclusive learning environment, every student can actively participate and thrive in their mathematical journey.

New vocabulary

Numbers, Numeric Forms, Tens

Work Flow
  1. Warm-up                           10 min.
  • Before the activity, cut and stick/tape the number cards from 1 to 10 in different locations around the classroom. (Annex 1)
  • Ensure that the number cards are visible and accessible to all students.
  • Gather the students in a circle or at a designated starting point in the classroom.
  • Explain the activity to the students. Let them know that they will be going on a "Number Scavenger Hunt" to find and identify the numbers in the classroom.
  • Play fun and upbeat music in the background to add excitement.
  • Start the scavenger hunt by calling out a number (e.g., "Number 5") or showing a number card to the students.
  • Encourage the students to find the corresponding number card in the classroom and bring it back to the starting point.
  • Once a student finds the number card, ask them to say the number aloud and show it to the rest of the class.
  • Celebrate the students' success and encourage positive interactions among them as they search for the number cards.
  • Repeat the scavenger hunt with different numbers, allowing each student to have a chance to find and identify the numbers.
  • If time permits, you can increase the challenge by asking the students to find numbers in sequential order (e.g., 1, 2, 3, etc.).
  •  Guided Learning                              70 min.
  • In this guided learning activity, students will use their imagination and senses to explore numbers and objects in various contexts.

  • Guided Imagery:
  • Begin by asking students to close their eyes (if comfortable) and take slow, deep breaths. As a facilitator, guide them to imagine being in a calm and relaxed place. Encourage them to work out the details in their minds, such as what they can see in that special place. Prompt them to count the number of objects present and identify which object appears most frequently. Engage their senses by asking about the sounds, smells, and colors of the place, and if any of these are associated with specific numbers or colors. Finally, instruct the students to open their eyes.

  • Number Hanging and Group activity
  • Hang numbers between 1 and 10 from Annex 1 in appropriate places around the classroom.
  • Form pairs of students and provide each group with visuals from Annex 2 by printing and cutting the picture cards.
  • Ask the students to determine the number of objects in their visual and paste it next to the corresponding number in the classroom.
  • Counting Sticks activity
  • Distribute counting sticks (30 pieces) to each student.
  • Display one of the number cards (between 1-20) from Annex 1 on the board.
  • Invite a student to take as many counting sticks as the number displayed on the card. Ask students sitting closely to each other to double check their sticks.
  • Real-Life examples
  • Encourage students to provide examples of objects in the classroom and their corresponding numbers:

    How many tables are there?

    How many female students can you count?

    How many male students are in the class?

    How many windows do we have, etc.

    Through this guided learning approach, students will actively engage with numbers and objects, connecting them to real-life experiences and enhancing their understanding of numerical concepts. The activities are designed to promote a positive and inclusive learning environment, allowing all students to participate and thrive in their mathematical journey.

Reflection

In an additional activity, the subject is reinforced through interactive learning methods. If available, tablets can be provided to the students, or Match The Numbers Game and Group The Numbers can be played on the smart board. This activity aims to engage students and solidify their understanding of the concepts taught in the lesson. The duration for this activity is approximately 5 minutes.

As a homework assignment, the class gets the task to find objects that represent the numbers from 1 to 20 using items they have at home. Students can capture a video of themselves showcasing the objects and their corresponding numbers. This activity encourages students to apply their counting skills in real-life scenarios and fosters a connection between classroom learning and everyday experiences. Students can then send the video to the teacher, further promoting engagement and active participation in the learning process.

In case they have difficulties to understand the instructions, reads the task instructions with the SEN students.

New vocabulary

unit, tens, place of units and tens in the two-digit number

Work Flow

1. Update of basic knowledge – group work

The teacher says: We will start the lesson with dividing the class into three groups. The teacher groups the students into 3 groups - a group of 3 students, a second group of 5 students and a third - of 10 students. The task of each group is to count how many students there are in their own group and in the groups of the others and write down the number of students in each group on a sheet.

І group

ІІ group

ІІІ group

  The results are presented to everyone, the numbers are compared. Students answer questions:

- How many individual students does the first group consist of?

- How many individual students does the second group consist of?

- How many individual students does the third group consist of?

- Which group has the fewest students?

- Which group has the most students?

- Who is the group in the middle?  

A record of the comparison is made on the board: 3 < 5 < 10.

Time: 5 minutes.

2. Setting the topic and presentation

The teacher says:

- We see that in the group with the most students we have 10 students. That's quite a large number of individual students. A group of 10 separate units forms a ten. We say that the sum of 10 units is one ten.

- Now we will see what the difference between a unit and a ten, how to form and write a ten.

The next step is the presentation in Appendix 1 - Presentation. During the presentation, the teacher explains simultaneously with the visualization of the different slides.

- And now we already know the numbers from 1 to 10.

Slide 1 - We can easily see that the pencils are 10.

Slide 2 - One pencil is one unit. Then 10 pencils are equal to ten units.

Slide 3 - Ten units make one ten.

Slide 4 - The opposite is also true - 1 ten is equal to 10 units.

Slide 5 – Now let's see some examples. If we add another 5 units to 5 units, we will get 10 units or 1 ten.

Slide 6 – However, if we subtract 5 units from 10 units, we get 5 units.

Slide 7 – If we add 2 units to 5 units, we will get 7 units. Do we have a whole ten? No, we don't have a ten yet because we don't have 10 units.

Slide 8 – However, if we add 3 units to 7 units, we will get 10 units or one ten.

Slide 9 – However, if we subtract 3 units from a ten, we will have 7 units.

Slide 10 – Now, look at some examples. We will compare 5 units to 3 units plus 3 units. We get 5 units on one side and 6 units on the other side. 5 is less than 6. Therefore, 5 units is less than 6 units.

Slide 11 - We have 9 units minus 4 units that we need to compare to 2 units. We get 5 units. 5 is bigger than 2, therefore 5 units is more than 2 units.

Slide 12 – We will compare 3 units with 3 units. 3 is equal to 3. So, 3 units is equal to 3 units.

Slide 13 – Today we will focus on the difference between a unit and a ten, how to compare them, and how to add and subtract using them.

After the presentation, the teacher explains the way number 10 is written on the board:

- One ten is formed of ten free units.

In two-digit numbers, the tens digit is written in the first position and means the whole first ten, and the units digit is written in the second position and means how many units of the second ten are involved in the number. Such a two-digit number is the number 10.

Time: 10 minutes.

3. Working with the whole class

The teacher presents the content of Appendix 2 - Presentation.

The teacher says:

Slide 1: We're going to play a game. Let's recall how we compare numbers. The crocodile comes to help us. It always feeds on those animals that are an extra number.

Slide 2: A bigger than symbol tells us which of the two numbers we are comparing is the bigger one. The crocodile's open mouth points to this number.

Slide 3: The smaller than symbol refers to numbers that are less in number.

Slide 4: We use the equal to symbol when we have an equal number on both sides of the equation.

Slide 5: We will use the signs <, ˃ or = to solve several maths tasks.

For each slide from 6 to 11, the teacher invites a student who goes to the board, chooses a sign <, ˃ or = and, using a marker, writes it in the circle. If the board cannot be used to write on it with a marker, use Appendix 3 – symbols bigger than, less than, equal to and with the help of a double-sided tape, the student can attache the symbol of their choice to the circle on the corresponding slide.

Time - 5 minutes

4. Group work with manipulatives

This part of the lesson uses a decimal block and 10 free single units from the "Decimal Cube" set (Appendix 4 - photo of a decimal block with 10 single elements). 

The teacher says: I see you are doing very well. I will now divide the class and you’ll work in groups.   

The class is divided into several groups of 5 students each. The group receives a decimal block with ten unit cubes, a dice and Appendix 5 - Worksheet for group work with manipulatives. Students from each group take turns rolling the die and placing as many elements on the decimal block as the die shows. Then they add the number of units from the decimal block by 1, by 2, by 3 or by 4, depending on the group in which they are included. SEN students join the group that adds by 1, for example. Each participant, after taking his turn, records the result of the calculation in the table opposite to their name.

As an additional task, each participant can be given to compare his number with the student's numbers before and after him, for example 5 units is less than 7 units, but is more than 3 units.

Time – 5 minutes.

5. Individual work

Teacher says: You did great. Now let's see if you have understood everything and if you can handle it yourselves.

 Each student receives a worksheet Appendix 6 - Worksheet for individual work.

6. Homework

Students are given a copy of Appendix 10 - Homework.

Reflection

The teacher says: - I see that you are very fast and doing excellently. You will get a sheet of paper for each of you to share what you found interesting and easy.

Students are given a printed copy of Appendix 8 - Reflection and they answer the questions individually.

 Time – 3 minutes

Location: Classroom/Interior.

No. of participants: All the students in a class.

Organisation: Students stand in a circle.

The names of three fruits are chosen: pear, apple and banana;

Each fruit is associated with a gesture: pear - clap your hands; apple - jump backwards; banana - hold up your hands.

The teacher names the fruit randomly, which the students have to match with the correct gesture. Whenever a student makes a mistake, they leave the game. The pace at which the fruit is named can be increased in order to increase the difficulty of the game.

Relaxing Exercises senpower     33 - I am a tree

This game consists of students acting like a growing tree. With relaxing music in the background and low lighting, Imagine you are a seed in the soil which grows into a large tree.

Start in a kneeling position with your heads tilted downwards. Then you squat and gradually start rising up and stretching your arms upwards as if they were large branches.

This relaxing exercise can be repeated a few times explaining that the wind blows the seeds away and the grow into new trees.

Objectives

In the end of the lesson should be able to:

  • Participate in the definition of a data collection method.
  • Identify how to observe or survey and how to respond.
  • Collect data through observation or enquiry.
Preparation

Resources:

  • Board available to record answers;
  • Students' scissors;
  • Computer with speakers;
  • Internet access;
  • Task record sheet;
  • Scratching material.
Introduction

Start the lesson by talking about the importance of eating fruit.

Explain what a data collection method is, using simple language and examples from everyday life.

Discuss different methods, such as interviews, questionnaires and observation.

Use practical situations close to the students to experience and involve them in learning.

Teaching and learning methods
  • To raise awareness of what is being learnt, encourage learning based on concrete situations that are close to the students;
  • Active/experiential learning that allows students to develop increasingly important instrumental skills for understanding, explaining and acting on the environment in a conscious and creative way;
  • Learning that takes into account the diverse starting points and learning rhythms of students, their interests and needs and the characteristics of the environment;
  • Learning that values themes and/or generating questions arising from observation of the reality that is close to the students and that enables them to problematize and investigate;
  • Co-operative and collaborative learning - Work carried out in cooperation and collaboration in groups and pairs;
  • New technologies as a way of learning/consolidating content.
Interdisciplinary connections

Mother Tongue - Select relevant information according to the listening objectives and record them using different techniques. Speak clearly and articulate words appropriately.

Citizenship and Development - Sustainable Development; Environmental Education

Resource teacher or other specialists activities

All the steps in exploring the topic are understandable for students with specific needs but cognitive abilities. The lesson does not include lengthy written explanations. The role of the support or special education teacher is to help the students in the target group if they are unable to carry out any of the tasks or steps, or if they feel disorientated in understanding something that may be asked of them.

Identifying and manipulating and handling materials, taking part in games, exploring content by visualising images, etc. are usually well accepted and meet the interests and needs of most students.

New vocabulary

Enquiry

Collecting data

Data recording

Work Flow

1st step - Large group

Start the lesson by talking with students about the importance of fruit and its health benefits, particularly in terms of vitamins.

Show a picture of fruit items.  (Appendix 1).

Since fruit is so important for boys and girls to grow up healthy, we want to know if boys and girls usually eat fruit and what their favourite fruits are.

How are we going to collect this information?

2nd step- Pair work

Give each pair two interview record sheets (appendix 2) and ask the students to take it in turns to be the interviewer and the interviewee, recording their answers on the sheet provided.

Meanwhile, the teacher writes the title ‘YOUR FAVOURITE FRUIT’ on the interactive whiteboard or on the normal classroom whiteboard, and line by line the names of all the fruits on the recording sheet.

3rd step – Large Group

The teacher collects the record sheets (appendix 2) and without identifying names  he / she uses the interactive whiteboard or the classroom whiteboard to record the fruits that have been registered by the students using a vertical line.

4th step - Pair work

Observing the records made by the teacher, in pairs the students fill in the table (appendix 3) counting the fruits preferred by the students in the class.

The teacher helps the class by projecting the same table and noting the results the students have obtained and finalising the results.

5th step - Individual work

Afterwards reflect with the students on the importance of collecting information to better understand the world around us.

Encourage students to think of other situations in which they could use data collection methods ( favourite colour,extra school activities,...).

In order to check the students’ comprehension about the topic, give them a worksheet with a challenge for them to solve individually. This time about colours. (Appendix 4)

The results will be verified / corrected through a projection on the interactive board. (Appendix 5)

Reflection

Thumbs UP and Down Game  

The teacher asks the students which activity they liked best.

If they liked it, the students make a positive sign with their thumbs up; if they didn't like it or liked it less, they tick with their thumbs down. The teacher records the results on the board.

Location: Classroom/Interior as free as possible.

No. of participants: All the students in a class

Organisation: 2 groups sit on the floor in a row behind each other.

Material: 2 balloons.  

Description

Organise two rows side by side, with the students sitting one behind the other. The teacher gives a balloon to the first person in each row who, on the teacher's signal, must pass it on to the next person, without anyone dropping it. When the balloon reaches the last member, he comes to the front of the queue and continues along the line.  Whenever someone loses the balloon, the balloon goes back to the beginning, i.e. to the first person.

Relaxing Exercises senpower     32 - Arms and Shoulders

With each student sitting in their place in the classroom, give them clear instructions:

Let's pretend you're a very hairy, lazy cat. And you want to stretch. Extend your arms forwards. Raise them above your head. Pull them back. Feel the pull in your shoulders. Extend them even further. Now let them fall normally.

O.K., kitty, stretch again. Stretch your arms forwards. Raise them above your head. Pull them back. Pull hard. Now let them fall normally. That's good! Notice how your shoulders are more relaxed. This time we're going to stretch for real. Try to touch the ceiling. Spread your arms out in front of you. Raise them above your head. Pull back. Notice the tension and pull in your arms and shoulders. Hold on tight. Great! Drop them quickly and feel how good it feels to be relaxed. It's nice, warm and cosy.

Objectives

 In the end of the lesson should:

  • learn the importance and necessity of taking measurements.
  • understand and measure different fulfilments using non-conventional and conventional units.
Preparation

Resources:

  • Clothes clips, glue sticks (one set per two students)
  • Two tape measures (for the practical activities: one to attach to the wall, the other to measure the table)
  • Rulers (one for every two students).
  • Record sheet
  • Scratching material
  • Computer with speakers
  • Internet access

Preparation:

On an empty wall in the classroom, fix a tape measure vertically from the floor with tape or sticky gum.

Introduction

Start the lesson by talking about the importance and necessity of measuring objects in the house, so that, for example, you can buy a bed that fits in the bedroom, etc.

Explain that there are various ways of measuring. Present a set of unconventional objects and encourage the students in pairs to take measurements with them and record them on the recording sheet.

Suggest that they share their results.

Introduce conventional measuring instruments, ruler and tape measure and show the students how to use them.

The students should share their results and come to the conclusion that they are the same size when using a ruler or tape measure.

Teaching and learning methods

  • To raise awareness of what is being learnt, encourage learning based on concrete situations that are close to the students;
  • Active/experiential learning that allows students to develop increasingly important instrumental skills for understanding, explaining and acting on the environment in a conscious and creative way;
  • Learning that takes into account the diverse starting points and learning rhythms of students, their interests and needs and the characteristics of the environment;
  • Learning that values themes and/or generating questions arising from observation of the reality that is close to the students and that enables them to problematize and investigate;
  • Co-operative and collaborative learning - Work carried out in cooperation and collaboration in groups and pairs;
  • New technologies as a way of learning/consolidating content.
Interdisciplinary connections

Mother tongue- Select relevant information according to the listening objectives and record them using different techniques. Speak clearly and articulate words appropriately.

Resource teacher or other specialists activities

All the steps in exploring the topic are understandable for students with specific needs but cognitive abilities. The lesson does not include lengthy written explanations. The role of the support or special education teacher is to help the students in the target group if they are unable to carry out any of the tasks or steps, or if they feel disorientated in understanding something that may be asked of them.

Identifying and manipulating and handling materials, taking part in games, exploring content by visualising images, etc. are usually well accepted and meet the interests and needs of most students.

New vocabulary

Non-standard measures

Conventional or standard measures

Work Flow

1st step - Large group

Start the lesson by talking to the students about the need to take measurements (the height of the students, a piece of furniture in their house, a plot of land, etc.).

2nd step - In pairs

Organise the students into pairs.  Give each pair a sheet for recording, (appendix 1) a clothespin, a paperclip and a tube of glue (these objects must all be exactly the same).

Then instruct each pair to take measurements using non-conventional units, i.e. using the clothespin, paperclip and tube of glue, and record them on the sheet. The students should measure the pen, the elasticated cap, the training notebook and their desk.

- How many clothes pegs, the pen, notebook and cover measure?

- How many paperclips does the pen, notebook and cover measure?

- And how many glue sticks does the pen, notebook and cover measure?

The students (in pairs) are also asked to measure their desks with an open hand and to say how many palms the desks measure (which are all the same size).

3rd step - Large group

The students will share their data in order to check the results (the same or different). On the board, the teacher will record the results in columns.

The supposedly different results will allow the teacher to explain the need for a standard measure.

4th step - Large group

Next, the teacher explains what standard measures are, what they are used for and how they are used – he/she chooses to show a tape measure and a ruler.  Following this explanation, the teacher shows some illustrative images which he projects onto the video projector (appendix 2).

Showing a ruler and tape measure, he/she exemplifies by measuring some objects with the ruler and one of the work tables with the tape measure.

On an empty wall of the room, where the tape measure is already fixed vertically with glue or adhesive tape, she selects a pupil, using a random name selector, name wheel or online roulette available on Google, to be measured. This activity of measuring all the children is left to be continued in another class, or on another day.

5th step - In pairs.

Again, in pairs, give each pair a ruler and ask them to remeasure the pen, the elasticated cap, the training notebook. Record the results on the record sheet used earlier (Appendix 1).

6th step - Large group

The students will share the data they have obtained and come to conclusions when they see that when using a standard measure, the results obtained are the same, which is not the case when using objects with their hands... to measure something.

Reflection

Bring the class together and highlight the discoveries made during the lesson.

  • Ask the students about the differences between the units of measurement used.
  • Emphasise the importance of precision when measuring.

New vocabulary

Word problems

Work Flow
  1. The lesson starts with updating the students' knowledge and skills of addition and subtraction of numbers up to 20. Each student is provided with a copy of Handout 1 to complete the tasks.

In Task 1, students must use the information from the illustrations and calculate the sum and the difference.

In Tasks 2 and 3, the objects in the problem description are given by drawings. Pupils need to count the objects in order to identify the numbers, and then - calculate and write down the answers to the problems.

(5 min)

  1. The teacher opens the presentation in Annex 2 and shows the illustration; the students are asked to describe what is depicted.

Then, the teacher shows the text of the word problem. The class discusses whether the illustration and the text of the word problem correspond to each other. The teacher explains that in mathematics there are problems that are described only in words and they are called word problems. By using annex 2, the teacher introduces the elements of a word problem: (1) description of the word problem with numerical data and (2) question, and explains what the terms mean.                 (2 min)

  1. Each student receives Handout 3.

In Task 1, students have to read the texts and identify the one that is a text problem.

In Task 2, students have to find the suitable question to the problem description.

In task 3, students need to highlight the different elements of the word problem and identify the numerical data.

The tasks are checked with the whole class; the teacher provides comments and further explanations where needed.                  (5 min)

4. The teacher explains the different steps in solving a word problem (slides 6 and 7, Annex 2). Special attention is paid to the word(s) in the question which is (are) a clue(s) for deciding which arithmetic operation that must be performed to solve the problem (addition or subtraction).                    (5 min)

5. Students are divided in groups. Each group is given an addition or subtraction problem from Handout 4. Students copy the text of the problem on a A3 sheet. After that, they cut out the questions and stick them in the logical order they should be answered in order to solve the word problem. Finally, the put down their answers to the questions. If the teacher decides, they can include a step in which the students make drawings to illustrate the problem (10 min).

6. Students work in pair with Handout 5.The task is to discuss together and distribute the provided words in the 2 columns considering if they imply performing the arithmetic operation of addition or the arithmetic operation of subtraction. The teacher can play the word problem from Annex 2 to provide a practical example of the task. When the pairs are ready, the results are summed up. The white board is divided in 2 and the + sign is written on the left side, and the - sign – to the right. Students volunteer to list words belonging to the addition (+) side, and the subtraction (-) side. Alternatively, the split can be put recorded on 2 A3 sheets of paper and, once completed, could be hung in the classroom to support the process of solving word problems throughout the school year.                                        (5 min)

7. The teacher distributes Handout 6; students work individually.

In Problem 1, students must connect each description to the corresponding question to produce a meaningful word problem. After that, they need to identify which problem is to be solved by addition and which one - by subtraction.

In Problem 2, students number the parts of the word problem sequentially, and after that - solve it.

In Problem 3, students write the solution and the answer in the provided boxes.

(10 min)

8. After completing the problems in Handout 6, the teacher summarizes the highlights of the lesson. (2 min)

Reflection

Activity 1. Ask the following questions:

  1. was the most useful thing you learned today?
  2. Which activity did you like most?

- the energizing exercise

- the relaxing exercise

- the group work to solve a text problem (step 5)

- the pair work in splitting the words (step 6)

- the individual work (step 7)

Activity 2. Each student receives the picture of traffic lights with the different faces (Handout 7) and has to choose and colour one of the faces according to  their opinion of the lesson:

- green if they are satisfied with what they have learned and with their work;

- yellow if they are not very satisfied because they didn’t understand everything or were bored;

- red if they are not satisfied because of some reason.

The coloured traffic lights presenting students’ feedback are displayed on the classroom walls after the lesson.  (5 min)

The activity can be repeated several times changing the last person in the line who starts the game.

Relaxing Exercises senpower     3 - Guided breathing

Teacher asks the students to close their eyes (if comfortable), inhale for a count of four, then exhale for a count of four (all through the nose, which adds a natural resistance to the breath). Then, with one hand on the chest and the other on the belly, the students can take a deep breath in through the nose and exhale through the mouth, ensuring this way that the diaphragm (not the chest) inflates with enough air to create a stretch in the lungs

Introduction

You already know the numbers up to 20; you can compare them, add and subtract them, you can even solve addition and subtraction word problems. We have looked at various cases of addition and subtraction, but in this lesson you will be introduced to a special case of addition – adding number 9 to a single-digit number with carrying. To calculate the sum, you will use your existing knowledge and skills. And, at the end of the lesson, you will see that this is not complicated at all.

The steps in the lesson are comprehensible to most students with special needs who have well-preserved cognitive abilities. The text and instructions of the tasks are short and clear. The role of the support teacher is to help students if they don’t understand the instructions.

New vocabulary

Addition with carrying

Work Flow

Step 1 (5 min.)

The lesson begins with updating students’ past knowledge and skills. Each student receives Handout 1 and works individually.

In task 1, students have to write the missing number so that the sum is 10. They can use the number strip  as support.

In task 2, students have to calculate the sum of number 10 with a single digit number. They can use the number strip  as support.

In task 3, students have to represent the provided one-digit numbers as the sum of number 1 and a single-digit number.

Step 2 (10 min.)

The teacher opens the presentation (Annex 2) and shows the illustration from slide 2; students are asked to describe what they see. Then, as a group activity, they have to come up with the text of a word problem based on the illustration. The teacher explains that several actions must be performed in order to answer the question. However, this case of addition is different compared to what they have done in class so far. And this is what needs to be done.

The teacher goes to slide 3 and demonstrates the addition of numbers 9 and 3, and the algorithm for adding number 9 to a single-digit number with a carrying:

  • number 3 is represented as the sum of 1 (because 1 complements 9 to 10) and 2;
  • 1 is added to 9 and the remaining units of number 3 are added to the resulting number 10.

Then, once again, demonstarates the algorithm, but applied to the sum of numbers 9 and 4 (slide 3).

Step 3 (10 min.)

Each student receives Handout 3.

In task 1, students will visualize the addends by first adding up to 10 and then calculating.

In task 2, students have to calculate the sums and match each expression with the correct number.

In task 3, students represent the second addend as the sum of 1 and a single digit number, and then calculate the sum.

The first examples in each task are to be solved together with the whole class. Then, students work individually on the handout, and finally, they check the answers as a whole-class activity.

Step 4 (5 min. – work in pairs)

Еach pair is provided with the two cards from Handout 4 and a dice (student 1 receives worksheet 1, and student 2 - worksheet 2). Student 1 rolls the dice and puts down the number in worksheet 1 (row 1). Then he/she rolls the dice 2 more times and records the numbers in the 2nd and 3rd rows. The teacher explains that the  three addends in the rows need to be different, therefore, if there is a repetition of the points when rolling the dice, it needs to be rolled again. After the first student completes worksheet 1,  student 2 takes the dice and performs the same actions to fill in the addends in worksheet 2.

Тhe two students exchange their worksheets and solve the problems.

The teacher writes on the board/flip chart all the possible cases of adding 9 to a single-digit number. Students volunteer to write down the correct answers.

  • : If there are students who find it difficult to calculate the sums, the teacher can give them a number strip from Handout 5 and explain that the sum can be found by counting forward, starting from number 9. Another option is to prepare two-color tokens or other manipulatives so that the students can visualize the sums by firstly adding up to 10 and then adding the remaining units from the second addend.

Step 5 (10 min.)

Distribute Handout 6 to each student. Students work independently on assignments, and the teacher monitors their work, correcting and providing support if necessary.

In task 1, students need to calculate the sums.

In task 2, students calculate the sum, find the answer among the provided numbers and colour it.

Problems 3 and 4 are word problems with addition (the new case from the lesson).

Step 6 (2 min.)

After completing the tasks from Handout 6, the teacher makes a summary of the algorithm for addition presented in the lesson.

Reflection

Ask students the following questions (3 min.):

  1. What is the most useful thing you learned today?
  2. Which activity did you like most?
  • The energizer Broken telephone.
  • The relaxing activity Guided breathing.
  • The activity with the dice.
  • Doing the problems from Handout 6.

Praise students’ diligent work and learning something new.

Energizers senpower     20 - Chief of clan

Everyone stands in a circle. One participant closes his/her eyes or steps out of the room. He/She will have to guess who is the chief of the clan. One participant volunteers to be the secret Chief (quietly, so the "guesser" can't hear anything). The chief begins an action such as snapping fingers, patting the tummy, or slapping knees, and everyone in the circle imitates him/her.  The guesser returns to the room and tries to figure out who the chief is. As the guesser looks around, the chief changes the action avoiding being detected.

Relaxing Exercises senpower     19 - Massage ball

One ball is given to each participant and, following the rhythm of a soft music, they place the ball between their back and a wall. They bend their knees slightly to relax the legs and better place their back. Then they move their body from top to bottom and from right to left and vice versa, moving the ball around their back. When making movements of their body, they will notice some more tense (and sometimes painful) spots. When they notice this they should stop and stay quiet keeping their back against the wall, making the desired pressure and holding for a while.

Variation: Do not use the wall. Participants work in pairs and one holds 1 or 2 balls in their hands and makes the massage to the other and then they switch.

Objectives

Students will:

  • understand the meaning of multiplication and how to write it mathematically;
  • write a sum of equal addends with multiplication and vice versa;
  • become familiar with the terms multiplier and product;
  • use the names of the components and the result when solving multiplication problems;
  • develop a positive attitude towards mathematics;
  • gain confidence in their capabilities;
  • develop their teamwork skills.

  6. Prepare one card with a circle drawn on it for each student (for the reflection activity).
Introduction

Do you like homemade biscuits? Probably yes. Imagine that your mother has prepared your favorite biscuits. You already know the numbers up to 100, so you can count how many cookies she baked and how many of them you have already eaten - yummy, yummi. You can also count how many biscuits are left.

Okay, now imagine that your mom decided to please you and baked 6 trays of biscuits. How long will it take you to count all the biscuits if there are 10 in each tray? It takes a bit longer to count one by one.

In this lesson, you will be introduced to multiplication and learn how to add equal addends quickly.

Work Flow
  1. Launch the presentation

Show the solution to the problem using addition. Then direct students' attention to the addends. Emphasize the fact that they are equal. Explain that in cases like that, the problem can be solved with multiplication. Play the presentation to show the second solution. Specify the way of reading the expression when the solution is written and the semantic meaning of the numbers involved in it.

Read it specifying that we want to know the total number of biscuits, which are represented as 3 groups, each consisting of 2 biscuits. Write the solution as a multiplication problem and once again read it: "3 times 2 biscuits" or "3 times 2". Pay attention to the mathematical sign we use for multiplication.

Summarize that the sum of equal addends can be represented by multiplication. (5 min.)

  1. Distribute Handout 2 to each student. Students should determine and write down the number of groups and the number of objects in each group, then represent the total by multiplication without doing the calculations. (10 min.)
  2. Distribute the cards from Handout 3 to each desk/table. Students work in couples. Ask them to put the cards in the correct order - illustration, addition expression and multiplication expression.

If you can provide digital devices for the students, you can use the application https://puzzel.org/en/features/create-jigsaw-puzzle  to create puzzles for the students to put together on their devicee, for example https://puzzel.org/en/matching-pairs/play?p=-NdX4x10uK4uRZl5awVs or https://puzzel.org/jigsaw/play?p=-NZ03nNLzJwJslax_LBu   (5 min.)

  1. Distribute to each table/desk:

• 2 dice, preferably in a different colours (e.g. blue and red);

• 6 cardboard plates;

• a set of colored sticks;

• a writing sheet.

Students work in couples. They take their turn to roll the dice - the blue dice is for the number of groups and the red dice is for the number of objects in each group. The student who threw the blue dice arranges in front of him as many plates as the number of sports on the dice. The second student puts in each plate coloured sticks corresponding to the number of sports on the red dice he rolled previously. Students write down how many groups there are and how many subjects there are in each group by using multiplication, and then calculate the total number of objects by using addition. For example, if the couple has 2 plates with 4 coloured sticks in each of them, they have to write it mathematically as follows: 2 x 4 = 4 4 = 8.

After that the roles in the couple are swapped.

Each couple should write down 6 multiplication problems and calculate them with addition. The teacher exchanges the sheets among the groups and sets a time limit for each couple to check the worksheet it has received. Fanally, all couples report the rasults. (15 min.)

  1. Students continue to work in couples. They receive the square grid sheet from Handout 4 and the cards with the problems cut separately. Each student in the couple has to pick up two cards and take turnes to colour the correct number of squares in the square grid.

For example, if a student has picked up the card with the expression 3x4, he/she has to colour squares in 3 rows – 4 squares in each row,

or 4 rows with 3 squares in each row.

Then, on the right side of the grid, students write the problem using addition and calculate the sum to find the total number of coloured squares. (10 min.)

  1. Launch the presentation.
    Introduce the terms multiplier and product. We use the term product both for the expression 6x10 and for the result - 60. Use the expressions from slides 5, 6 and 7 and have students to identify the multipliers and the product in each expression by completing the sentences orally:

The multipliers are: ___ and ___.

The product is: _______ and ___. (5 min.)

  1. Task: Write down and calculate using addition the product of two multipliers.

Option 1: Use the application https://pickerwheel.com/ to organize a mathematical dictation. Spin the wheel once to determine the first multiplier. Then spin it again to determine the second multiplier. Students have to write down the expression for the product of the two multipliers and calculate using addition.

If necessary, the action can be represented visually by slashes – the number of groups corresponds to the first multiplier, and the number of slashes in each group corresponds to second multiplier.

For each example, a student goes to the board, writes down the corresponding expression and reads it.

  • 2: Prepare small cards with numbers in advance and place them in a bowl or a box. Students take turns going to the bowl/box to pick up 2 cards and write the corresponding expression on the board. (10 min.)

Divide the class into groups of four. Simulate a shopping experience using the dice, coloured sticks, cardboard plates from the lesson activities and any other available materials of which you have a few. Distribute them among the groups. Give each group slips of paper to write down the price in cents of each item which can be purchased. Instruct students that the prices should be from 1 cent to 10 cents maximum. Explain that these are not real prices but are just for the game. In real life, prices are different, but the concept of calculating the total amount you pay when shopping is the same. Distribute the coin patterns among the groups. Groups must designate a cashier. The remaining three participants in each group will play the role of customers. Consecutively, each student indicates which item and what number he/she wants to buy, calculates the amount to be paid by using multiplication (if necessary, the student records it mathematically by using multiplication and calculates the total price by using addition) and pays to the cashier. The cashier collects the amount paid and, if necessary, gives back the change. The cahier writes down on a separate sheet how many and which items he has sold, as well as the money he received for each sale. This is what happens in real life. The game continues until all the available items have been sold or until the customers have spent all the money they have. At the end of the game, the sums described on the sheets of the customers are collected by the cashier and a check is made to see if he/she has collected the same amount of money. (20 min.)

8. Finish the lesson with e-games: Students play the games on their mobile devices or the teacher opens a game on the screen and volunteer students take turns to come to the front and play. (10 min)

2. Which activity in the lesson did you like most?

  • The energizing exercise Chief of the clan
  • The activity with the dice
  • The Mathematical dictation
  • The Shopping simulation
  • The relaxing exercise Massage ball.

Activity 2. Give each student a face card. Ask them to draw a face with an emotion that best presents how they felt during the lesson using the following colours:

green, if they are satisfied with what they have learned and with their work;

yellow, if they are not particularly satisfied;

red if they are not satisfied.

Set a time limit and after that ask students to hold up their emotion cards. Counts the number of green, yellow and red faces and report to the class. If you have enough time, students - representatives of the three groups could share the reasons for their choice of emotion. (5 min.)

After this procedure, the students in each group should line up in a row, from the lightest to the heaviest. The group that completes the task correctly as soon as possible wins the game.

Relaxing Exercises senpower     22 - Relaxing Song

Use of mimed song accompanied by a musical backing, sung/recorded by the pupils themselves.

(cf. video on .https://youtu.be/9TEdEKKkUWw )

Objectives

In the end of the lesson students should be able to:

- distinguish between conventional and non-conventional measures;

- recognise that mass (weight) measures are used to measure the weight of things or people;

- know that the kilogram is represented by kg and it is the main unit of mass measurements;

- weigh the amount of a body or a material;

- compare the weight of different objects/materials according to their magnitudes, using conventional and non-conventional measures;

- notice that everything around us has weight.

Preparation

Materials

  • Food products: various fruit items of different sizes - apple, pear, banana, orange..., bread, cheese and ham;
  • Two-arms plate scales - Schools usually have this type of material. If there isn’t  any of these materials in your school, find someone whom you can borrow it from, or in alternative improvise by constructing them using, coat hanger with wires and a wire hook at each end. Attention if you use these improvised scales, it is not possible to use metal weights, it is only possible to get an idea of what you might weigh;
  • Digital kitchen scales; (bring from home and ask someone who has them);
  • Digital bathroom scales; (bring from home and/or ask someone who has them);
  • Metal weights;

Here are pictures of all the food items to be used in the weighing and the scales used.

Utensils for making snacks and for snacking; (knife, salad bowl individual disposable but recyclable bowls, dessert spoons also disposable but recyclable and paper napkins;

  • Printed activities: Tables, shopping list and weight record sheet.
  • Computers;
  • Video projector;
  • Scratching material.

The classroom tables and chairs must be moved close to the walls, so that there is plenty space in the centre of the room for the game. Once the game is over, the pupils help putting the tables and chairs in the previous place.

Meanwhile, there should be a table with all the materials needed to carry out the plan.

Introduction

In our daily lives, we are in constant contact with mass measurements. When we go shopping, we can observe that many products are sold already packed in kilogram (Kg). Others, such as fruit and vegetables, have to be weighed. For this reason, it is essential to know the main and most usual weight measurements in our daily life, the kilogram/ kg and the gram.

Taking the topic Environment as an example, students will have to work on   different types of scales and use different types of materials. They are expected to sort out their recycling bin and weigh paper and batteries.  They will realise that it takes up a lot of paper and a lot of volume because paper is lighter than batteries. Batteries take up little space because they weigh more than paper, etc.

We can also get a sense of heavy or light concepts by using our arms, taking the milk cartons distributed in the class as realia: the weight of the cartons before the milk is consumed and afterwards the weight of the same cartons when they are empty.

Teaching and learning methods

Integrating the students' daily life experiences in the teaching and learning process;

Learning based on concrete questions/situations and close proximity to the students;

Learning by the effective manipulation of material, making the awareness of what actually is being learned easier;

Cooperative and collaborative learning - Work developed in cooperation and collaboration in groups and in pairs;

New technologies as a way of learning or consolidating a content.

Interdisciplinary connections

Portuguese Language – Reading and comprehension.

Natural Science – Healthy snacks. 

Artistic Education (Relaxation moment is done with a musical support, recorded by the students themselves).

Physical Education – Dynamization of the game.

Citizenship and Development - Consumer Education

Resource teacher or other specialists activities

All steps of the topic teaching and learning process have to be understood by SEN students. The lesson does not include long written explanations.

The role of the support or special education teacher is to help the students throughout the progress if they cannot can't complete any of the tasks, any of the topic steps or feel confused during the process.

Students are expected to Identify and manipulate materials, play games, explore content through pictures. These are usually well accepted activities and meet the interests and needs of most students.

New vocabulary

Mass (weight); scales; kilogram/gram; measurements and estimate.

Work Flow

1st Step

Individual Task – Predicting:

Show to the students some pieces of fruit eaten at lunchtime (various different sizes of fruit and packed bread). The products are presented in pairs. Provide each student with a double entry table with three columns (my prediction...; what I check using my hands...; I check with the scales - table in handout 1), where students will mark in the first column, by estimate, what these products may weigh.

2nd Step

Individually, each student will measure and compare the weight of each pair of products presented in the previous exercise, using unconventional measures, by using their hands.  They register the results on the second column of the double entry table entitled "What I measured".

3rd Step

In groups of 4, students check the weight of the given products using a conventional measuring instrument, a two-arm plate scale.  Each student records the results on the third column of the double entry table entitled "I confirm with the scale".

4th Step

The class as a whole at this moment prepares a menu for a snack consisting of ham and cheese sandwiches and a fruit salad. Students start by listing the necessary products.

5th Step

In a small group of four, students jot down a list with the quantity of each product to be purchased by weight (this task activates their previous knowledge of conventional measurements).

The several groups compare their lists and conclude that some products have to be bought in kilograms and others in grams. See handout 2.

6th Step

Students with the teachers’ help must weigh each product, using two-arm plate scales for fruit and digital kitchen scales for cheese and ham.

7th Step

DOES AIR HAVE WEIGHT?

Before finishing the lesson, the teacher elicits students to answer this question by conducting an experiment: we need a wire hanger, two balloons, two paper clips and two pieces of cotton string of exactly the same size. Fill one balloon with air and leave the other empty, tie both balloons to each of the strings, which are already attached to the clips and these to the hanger. Observe as shown in picture 1 and answer the questions.

8th Step

Each group has to prepare their snacks.

9th Step

Students will carry out an interactive activity for assessment, using Kahoot.

10th Step

Convivial snack meeting.

Developed by NART
Grade 2
Duration 45
Energizers senpower     29 - Calculate in 2 steps

Divide students into 5 groups. It can be done by using playing cards. According to the number of students in the class, find out how many of the 13 ranks in each of the four suits: clubs (♣), diamonds (♦), hearts (♥) and spades (♠) you will need. For example: if there are 20 students, you will need 5 number cards - 5, 6, 7, 8 and 9. Shuffle the cards and let each child draw out their card. Then point out that the numbers of each colour form one team, and that the team formed will have to solve group problems.

If there is an odd number of children in the class (eg. 23), you can have coloured slips of paper for students to pick them up as they enter the classroom. Then, you will need 5 colours with 5 cards/slips of paper for each colour. In such case, some groups will become slightly larger. If you have more children in the class - you can decide whether to increase the number of groups. It’s up to each teacher to decide, according to the size of the classroom and the possibilities to set aside work area for each group.

Set up classroom space for each group to work and put a number in each area – so that the numbers 1, 2, 3, 4, 5 can be easily seen.

The way work places are designed should also give enough space for the movement of students between each of the work places. Place 1 red and 1 green pencil in each working space.

Print Appendix 1 five times. Put each copy in an envelope. Allow each group to draw out 1 envelope. The students do not know that they have the same tasks inside.

Ask each group to go to their table and open the envelope. Give them time to look at the problems, explaining that each group must solve the problems in the row that corresponds to the group number - group 1 solves row 1, etc.

The task includes 2 steps:

1. To perform the arithmetic operations on each row.

The first task requires finding the sum of 2 numbers.

Show this on the board with an example: 4 3 = .........

The second expression requires that you write the numbers from the first expression, swapping their places, and find the sum of the numbers again.

Show this on the board by writing 3 4 = ........

The third task requires subtraction operation to be performed. Each group has to illustrate it using the table below and colour the boxes they used to find the correct answer. Recall the rule starting from the first number in the expression and counting backwards. As many steps are taken as the second number in the expression shows.

Show through the example on the board:

Time for explanation and work: 5 min.

2. Now there is a change of places. 1st group goes to the second group space, 2nd group - to the 3rd, 3rd group - to the 4th, 4th group - to the 5th, and 5th group to the 1st group space.

Each group has to check, if the solution is correct. If it is correct, the group circles the answers in green, but if it finds an error, it writes the correct answer in red.

Working time: 3 min.

Relaxing Exercises senpower     27 - Commutative property in Mathematics

Go around and see how the groups have implemented their tasks. Collect the papers of the 5 groups. Ask the students to go back to their seats.

Ask them, if there was anything that impressed them.

Was there anything that made it difficult for them. Did they find any errors?

Draw their attention to the commutative property of addition.

Time: 3 min.

Objectives

Students will:    

• Perform arithmetic operations of addition and subtraction with the numbers up to 20.

• Know the commutative and associative property of addition.

• Make logical conclusions and build hypotheses.

Preparation

1. Arrange the classroom in a way that allows at least 5 sections for 5 groups to be formed. The arrangement should allow students to get back to their seats quickly and without shuffling after completing the group task.

2. Prepare the relevant number appendices:

Appendix 1 – 5 packs for group work;

Appendix 2 – for individual work, for the number of students;

Appendix 3 and Appendix 4 – only for students with special needs;

Appendix 5 – only for students who work faster, and Appendix 5a with a key.

3. The teacher and the resource specialist have to build a common understanding of the most important elements of the lesson which should be presented to students with SEN, so that they can understand the concept of the lesson and actively participate in the learning activities, and that should be an important part of the preliminary preparation.

The students with SEN will work with Appendices 3 and 4, with Cuisiner sticks and domino tiles, according to the individual characteristics of each SEN student after assessment have been made by both specialists.

Introduction

Implementing the activities within the topic students will add numbers with and without realignment.

The lesson is a transition from what was studied in the first grade and the increasing complexity of arithmetic operations in the second grade. The students should already be able to calculate single-digit numbers easily. If there are students who have not yet mastered dividing single-digit numbers, provide additional guidance using the approach described below.

They will also learn the method of subtracting with counting up to 10, addition and counting up after that.

Knowing the pairs that make up 10 will help students in the process of grouping numbers to make algebraic operations easier.

A good understanding of the grouping of numbers up to 10 will allow later to make well the transitions with grouping up to the nearest 10 for each ten up to 100.

The knowledge and skills to present the number 10 as a sum of two numbers, are essential for calculating the sum of three or more numbers. This will allow them to feel confident when it comes to adding two-digit numbers.

To go through the process smoothly, ask questions or give instructions in several different ways and give the students time to think before they answer.

Discuss with the class letting students come up with ideas on their own, give them hints and tips, if needed. Once you've introduced a concept, don't move further until all the students have shown comprehension and are ready to move ahead.

The psychological aspect reveals that each of these skills is the basis of building logical and creative thinking to discover rational ways of calculation, initiative in making a decision to use the "most convenient" method of calculation for the particular student.

That way self-confidence is built, which is the basis of learning.

Almost all the steps of the lesson are comprehensible to most special needs students who have well-preserved cognitive abilities. The lesson does not comprise long written explanations. The role of the special needs teacher or the assistant teacher is to help target group students in case they are not able to cope with some of the tasks or steps.

Learning materials that can be used for SEN students towards the implementation of the lesson activities are enclosed. The specific work steps are described below in the description of the preparation for the lesson and the actual process of conducting the lesson.

  • order of action
  • commutative property
  • associative property
Work Flow

1. Basic exercises for understanding the commutative property of addition.

1.1. Tell students that they will now continue discovering interesting things in mathematics.

Show the students the following text:

George has a birthday today.

and

Today George has a birthday.

The text can be written in advance on flip chart paper or displayed on a presentation slide.

Ask students how the two sentences are similar and how they differ.

The inferences should be in the direction that there are words moved around, but the expressions present the same fact.

Tell them that's how it goes in maths, too.

Ask the children to help you make a number expression by converting the number of letters in each word to a number. Ask them: how many letters are there in the name George - 6, etc., writing each number under the corresponding word.

The expression will look like this:

George has a birthday today - 6 3 1 8 5 = 23

Today George has a birthday - 5 6 3 1 8 = 23

Then show them the following two sentences:

Mimi and Ina are at the cinema.

Ina and Mimi are at the cinema.

Ask each of them to write down the numerical expressions in their own notebooks. Then ask 2 children to go to the board one after another and write down the numerical expressions. The solutions should be:

4 3 3 3 2 3 6 = 24

3 3 4 3 2 3 6 = 24

Ask again what they have discovered - the answers should be towards the fact that the order they follow in adding numbers doesn’t change their sum.

Resource teacher activities:

If children with SEN can count, the above exercise could easily be completed by any of them. The text with the sentences can be printed as a separate material for children with SEN.

If the child needs more engaging materials (other than text) you can use Cuisiner's sticks.

Use the stick that corresponds to the number to form with sticks the number expression. Each set of sticks allows you to do this. Each number is represented by a separate stick of a different colour, and children easily understand the relationship between numbers and their quantitative content.

The resource teacher explanations should be the same as of the main teacher.

1.2. Ask the children, if they know how to play dominoes. If there are children who do not know what dominoes are, you can show them a short film about the game. This is a short video in English:

https://www.youtube.com/watch?v=2x6r7DBdxhY&ab_channel=wikiHow

Show the students the following picture:

Ask them what the sum of the dots on the first domino block is – 6 1 = 7. Then ask them if we need to sum the numbers from the second domino block in the same row or do we already know the answer? If the children find it difficult - write again - 1 6 = 7.

Repeat the exercise for each subsequent row. Together with the children, draw the conclusion again that the order in which the numbers are summed does not change the final result. Introduce the concept of commutative property – the changing of number positions in addition.

Working time: 12 min.

Resource teacher activities:

If SEN students can count, the exercise could easily be completed by any of them. The text with the domino blocks can be printed as a separate material for children with SEN.

If the child needs more engaging materials (other than text) you can use real domino blocks and model the expressions.

The resource teacher explanations should be the same as of the main teacher.

2. Basic exercises for comprehension of the associative property in addition.

Tell the students that now you will find together another interesting way which will help us sum numbers more easily. So far we have convinced ourselves that the order in which we add the numbers does not matter. Now, however, we will discover ways in which we can group numbers to make calculation easier.

Write on the board or prepare on a slide the expressions:

7 9 = and 10 6 =

Write down the answers - 16.

Ask them which expression is easier to calculate. The answers should be in the direction that the second expression is easier to calculate.

Explain that sometimes we use number grouping strategies that allow us to calculate given expressions in an easier manner.

Remind the children of the grouping rules: 10 units make 1 ten.

We can introduce 10 either as 1 row of 10 boxes or as one solid block.

Visualize the ratio of 1 to 10 with this picture as well by asking students: How many units are in the block? And how many tens are there in the block?

Let them also answer each of the following examples.

Take a look with them at the scheme:

Circle all 10 blocks of the second row. This gives: 7 3 = 10 and 10 6 = 16. Write the expressions on the board.

Explain that in the first case we add 7 to 9 directly. This can be done by counting forward.

In the second case, grouping to 10 is done first, taking 3 blocks from 9. 6 blocks, which are added to the 10 blocks formed in the regrouping, remain.

That way, a difficult task, such as calculating the sum (7 9), can be turned into an easy one.

Leave the scheme and the number expressions on the board for reference and hand out Appendix 2 to the students.

Resource teacher activities:

Hand out Appendices 3 and 4 to students who need additional visual support.

To visualize the patterns, Cuisiner sticks can be used again.

While students are working on their own, go around the desks to check how each student is working.

If you have students who can cope with the tasks very quickly, prepare Appendix 5 for them (print without the answersJ). This type of exercise gives opportunity to the fast-working students to work extra while you observe how the rest are doing.

Working time – 15 min.

Reflection

Guided discussion:

Take 5 minutes at the end of the lesson to discuss again with the students what they have kept in mind. The main conclusions should be towards:

• the order numbers are calculated doesn’t change their sum;

• regrouping the numbers does not change their sum.

Tell them that in the next lessons the tasks will become more and more interesting.

Understanding the commutative property will help them not only when calculating with bigger numbers, but also when learning the multiplication table.

Everyone stands in a circle. One participant closes his/her eyes or steps out of the room. He/She will have to guess who is the chief of the clan. One participant volunteers to be the secret Chief (quietly, so the "guesser" can't hear anything). The chief begins an action such as snapping fingers, patting the tummy, or slapping knees, and everyone in the circle imitates him/her.  The guesser returns to the room and tries to figure out who the chief is. As the guesser looks around, the chief changes the action avoiding being detected.

Relaxing Exercises senpower     14 - Give me your energy

The students stand in a circle. The teacher starts, pretending he/she is holding a ball on the hands and passing it to the student on his/her right; this one do the same, until the ball comes back to the teacher. The ball needs to be passed in a gentle way, as it is very precious. At the second round, the teacher passes the ball to students in another side of the circle, making a gesture and a noise. The students will do the same until everyone will have touched the ball at least once.  The ball can be passed in any way (in form of kick, kiss…), pretending it becomes bigger or smaller depending on the will of the students. 

Objectives
  • Solve problems requiring four operations with natural numbers
  • Establish a connection between four operations problems and daily life.
  • Stimulate students’ imagination.
Preparation
  1. Print the imaginative math story that incorporates the four operations (addition, subtraction, multiplication, and division) (Annex 1).
  2. Print the the math problems related to the story (Annex 3) for handing out.
  3. Gather visual aids and manipulatives to support understanding and problem-solving.(Use Annex 2)
  4. Consider real-life objects or scenarios from students' backgrounds to make the lesson more relatable.

Materials: Whiteboard or blackboard, Markers or chalk, Paper and pencils for each student.

Introduction

Gather the students in a circle on the floor.

Start by telling them, "Today, we are going on a magical math adventure in the Friendly Forest! We'll encounter exciting math problems with the help of our Friendly Forest animal friends."

Review the names of the Friendly Forest animal characters (Benny the Bunny, Polly the Parrot, and Danny the Deer) from the math story.

Briefly discuss the four operations (addition, subtraction, multiplication, and division) and remind the students of their importance in daily life.

Teaching and learning methods

Storytelling: The use of an imaginative math story helps to engage students and make the math concepts more relatable. The story also provides a context for the math problems, which can help students to better understand them.

Problem-solving: The students are given a set of math problems to solve. This helps them to apply the math concepts they have learned and to develop their problem-solving skills.

Group work: The students are divided into small groups to work on the math problems. This allows them to collaborate with each other and to share their ideas.

Visual aids: The use of visual aids, such as manipulatives, can help students to visualize the math concepts and to solve the problems more easily.

Differentiation: The lesson plan includes a variety of activities and resources to accommodate different student abilities. This ensures that all students can participate and learn from the lesson.

Interdisciplinary connections

Language arts: The students could write a math story about the Friendly Forest animal friends. They could use the story to introduce new math concepts or to reinforce existing concepts

Art: The students could create a mural that depicts the Friendly Forest animal friends solving math problems. They could use different colors, shapes, and patterns to represent the different math concepts.

Science: The students could conduct an experiment to determine the best way to divide a pile of acorns equally among their animal friends. They could use different methods of division, such as cutting, counting, or weighing.

Resource teacher or other specialists activities

Instruction: Provide individual or small-group instruction to students who are struggling with the math concepts either through the use of manipulatives in all tasks or through individual instriction for the target group students.

New vocabulary

Addition, subtraction, multiplication, division.

Work Flow

1.      Story telling  and mathematics  (10 min.)

Play the picture from Annex 1 "The Math Adventure in Friendly Forest"  on the screen and start reading the story which you have previously printed. As you read, pause at key points to engage the students by asking questions related to the math problems encountered by the animal friends. Encourage the students to use their imagination to visualize the scenes and the solutions to the math problems; have volunteer students to come to the white board and write the problems from tha challenges in the Math Adventure story.

2.      Farm stories (10 min.)

Play the presentation (Annex 2) and ask students to come up with answers whenever a quiestion appears in the slide and write down their answers on paper; then play the next slide which provides the correct answer in visual format and have a volunteer to come to the whiteboard and write the rpoblem and the solution.

3.      Math Problems Exploration (10 min.)

Divide students into small groups and provide each group with a set of math problems related to the story (Annex 3). Each group will work together to solve the math problems, using the four operations. Circulate among the groups, providing support and guidance as needed.

4.      Connection to Daily Life (10 min.)

Gather the students back in a circle and ask each group to share one math problem they solved and explain how it relates to their daily lives. Discuss as a class the various ways math operations are used in everyday activities, such as sharing toys, counting objects, or solving real-life problems. Encourage students to share their unique solutions and reasoning.

Developed by NART
Grade 2
Duration 60
Energizers senpower     32 - Blocks game

Blocks game

Use Appendix 1 to prepare the working materials by printing as many copies as you will need.

Divide the students into pairs. Give each pair of students 9 blocks of tens and 9 blocks of units in an opaque envelope.

One of the students shakes the envelope, pokes in without looking, and takes out 7 blocks. The other one takes the rest. Each one writes down the number that they have drawn, and then the students combine the two drawn numbers to find out the sum. The students change the order and repeat the activity.

After that, ask those who wish to write down the numbers and the sum on the white board. Discuss the results with the whole class.

ASK: Why do all groups always get the sum of 99? (the blocks in the envelopes make 99). Why do we have so many different ways to sum numbers? (the students drew different combinations from the tens and from the units blocks). Who has more blocks - the one who has drawn 7 first or the one who takes the rest? (the one who takes the rest). Who gets the bigger number? Does the one with more blocks always have a bigger number? If the students confirm this, challenge them to come up with a way for a person to have more blocks, but a smaller number. If they don't answer, ASK: How is it possible that the person with more blocks have a smaller number? (one block of tens has more units than one block of units, respectively, the smaller number of blocks of tens can actually be a larger number than a larger number of units as individual blocks. Conclusion - the number of blocks does not tell us the number of units) .

Time – 5 min.

Relaxing Exercises senpower     30 - Grouping

Grouping of units and tens

Remind the children of the grouping rules:

10 units make 1 ten.

Illustrate the ratio of 1 to 10 with the picture as well (you can draw it on the board or show it on a slide), asking the students: How many units are in the block? And how many tens are there in the column?

We can present number 10 either as 1 column of 10 squares or as one block.

Tell the students that the tens block (point at the first block) is drawn very slowly and to make it easier for us, we sometimes draw it as one long block (point at the second block).

Objectives

Students should:

● represent a two-digit number as a sum of tens and units;

● know that one ten is equal to ten units;

● indicate the place of tens and unit digits in two-digit numbers.

Introduction

The activity aims to reinforce students' understanding of representing a two-digit number as a sum of tens and units. The required prior knowledge for this lesson is that students know the numbers up to 100 and can count to 100. Students will work with a variety of manipulatives to be able to represent two-digit numbers as the sum of tens and units. At the end of the lesson, they will be able to indicate the places of the units and tens in two-digit numbers and will be able to regroup tens and units to make addition or subtraction with two-digit numbers easier.

Work Flow

1. Ask the students to take out the envelopes with the ones and tens blocks. Tell them to use the blocks to write the numbers you will show them – 11 and 29.

Ask them:

How many tens blocks can replace 10 units? (1).

How many units can we use to show 2 blocks of tens? (20).

Continue the lesson by solving tasks 1 to 4 of Appendix 4.

At this stage, the resource teacher can use the unit cubes and 10 sticks from the Base 10 manipulative or Cuisenaire rods to help SEN students understand grouping as a process and recall the formation of 10 as being made up of 10 units. When solving the following problems, Cuisiner rods, Numberblocks or Base 10 can again be used.

Doing these exercises, students strengthen their skills in representing a two-digit number as the sum of tens and units and the grouping of tens and units.

Time – 12 minutes

2. Writing numbers without the help of decimal blocks. Write on the board:

4 tens and 6 units is the number 46

Ask the students to go one by one to the board and write down the number for:

● 5 tens - 50

● 8 units - 8

● 4 tens and 6 units – 46

● 6 tens and 3 units – 63

● 8 tens and 9 units – 89.

Ask the students how the the numbers 58 and 89 could be written using addition:

50 8=58 80 9=89

Write on the board and then do tasks 5, 6 and 7 of Appendix 4.

To solve the tasks in the appendix the resource teacher can work with SEN students using Cuisenaire rods, Numberblocks or Base Ten Blocks.

The activity aims at strengthening students' understanding of the order of tens and units in two-digit numbers. The lesson is directly related to the lesson representing a two-digit number as a sum of tens and units. The prior knowledge required for the students is to know the numbers up to 100 and they can count to 100. Students will work with a variety of manipulatives to be able to correctly and fluently determine the units order and the tens order in a two-digit number. At the end of the lesson, they will be able to point out the places of the units and the tens in two-digit numbers and will be able to regroup tens and ones to make addition or subtraction with two-digit numbers easier.

Work Flow

1. Presentation of numbers in two ways. Display 3 tens blocks and 4 unit blocks as shown below:

ASK: What number do the blocks show? (34)

SAY: I want to replace one of the tens blocks.

ASK: What can I replace it with? (10 unit blocks)

Change the tens block with 10 unit blocks as shown below:

ASK: Has this number changed? (not)

SAY: It means that the number 34 can be presented in different ways.

Do an exercise - Use the tens blocks to show the numbers in two ways.

a) 25 b) 37 c) 62

Sample answers:

a) 2 blocks of tens and 5 blocks of units, 1 block of ten and 15 blocks of units;

b) 3 blocks of tens and 7 blocks of units, 2 blocks of tens and 17 blocks of units;

c) 6 blocks of tens and 2 blocks of units, 5 blocks of tens and 12 blocks of units.

You can do this exercise in rows if the classroom tables can be divided into 3 groups. If the desks form 4 rows, add one more number to the above. The exercise can also be done in pairs or individually, and then it will take a little more time.

Draw on the white board:

ASK: Which two of these patterns can you use to show the number 34? (the first and the last) Which model does not show the number 34? (the model in the middle) What number does it show? (43)

SAY: What is the difference between the first and last pattern? (one block of tens is replaced by 10 blocks of units).

All these exercises can be performed by SEN students using the indicated manipulatives - Cuisenaire rods, Numberblocks, Base Ten Blocks.

Tell the students that now you are going to solve several problems, using rods for the tens and dots for the units.

Write 25 as shown below:

Time – 15 minutes.

2. Divide students into pairs. The task is to find all the ways to show 43 by using rods for the tens and dots for the units.

SAY: In each of the following examples, replace one block of tens with ten blocks of units.

Give them the Appendix 2 table and 5 minutes time to fill in all the blank spaces in the Task 1 table.

Tell the children that now you will show a number with the help of the tens and the units blocks. Show the sketch below:

Ask someone to come out and write the number.

Example: 73 = 7 tens blocks 3 unit blocks

Tell the children that they are now going to play a game and have to be creative thinking of a way to write 73 using the blocks by moving them. You should get the following:

6. Make copies of Handout 5 for each student.

7. Make copies of Handout 6 for each group.

8. Print Handout 7, cut out the traffic lights separately and hand out one image of traffic lights to each student.

Introduction

Look around. You can find many square-, rectangle-, circle- and triangle-shaped objects. Have you paid attention to the shape of the traffic sign at the zebra crossing? Triangle-shaped, of course. Other traffic signs have the same shape too. The triangle is similar in shape to a piece of your favorite pizza, to a clothes hanger, to the outline of some roofs and to many other objects that we don't even pay attention to. However, if you look closely, you will notice that although they are triangular in shape, these objects are different. In this lesson, we will learn about the different types of triangles considering the lengths of their sides.

Teaching and learning methods

Using manipulatives and visualization

Learning in small steps

Group work

Interdisciplinary connections

Arts - creating a picture recreating a scene from students' everyday life

Mother tongue - skills of expression

Resource teacher or other specialists activities

The steps in the lesson are comprehensible to most students with special needs who have well-preserved cognitive abilities. The text and instructions of the tasks are short and clear. The role of the support teacher is to help students if they don’t understand the instructions.

New vocabulary

Equilateral triangle, isosceles triangle, scalene triangle, leg of an isosceles triangle, base of an isosceles triangle.

Work Flow

Step 1

The lesson begins by updating students' knowledge of the geometric shape triangle and their recognition skills. For this purpose, use the picture with geometric shapes from Handout 1. Distribute one handout to each desk/table. Ask the students to look at the shapes; they have to find and circle only the triangles. Then ask them some questions related to the geometric shape triangle, for example: "How many sides does a triangle have?", "How many vertices does a triangle have?", "Are the sides of a triangle points or line segments?", “Are the vertices of the triangle points or line segments?” (4 min.)

Step 2

Distribute one triangle from Handout 2 to students for individual work. Ask them to measure the lengths of the sides of the triangle they have received using a ruler and record the results of the measurements in the appropriate places. Demonstrate the correct way of using a ruler when measuring the length of a segment. (3 min)

Step 3

Play the presentation (Annex 3). Ask the students who were supposed to measure the sides of the green triangle to stand up. Summarize with suitable questions that the sides of this triangle have equal length. Introduce the term equilateral triangle (slide 2). Then ask all students who worked with the blue triangle to stand up. In this case only two of the sides of the triangle had equal length. Introduce the terms isosceles triangle, lges and base of an isosceles triangle (slide 3). Finally, the students who measured the sides of the red triangle stand up. Ask students to compare the lengths of the sides of this triangle (all different) and introduce the term scalene triangle (slide 4). Sum up the three types of triangles based on the lengths of their sides (slide 5). (5 min)

Step 4

Each student receives a copy of Handout 4.

  • Task 1 students have to connect the red dots in the box on the right to make a triangle. Then, they have to measure the lengths of the sides of the triangle, determine its type based on its side lengths, and find its perimeter. Explain that regardless of the type of triangle, its perimeter is the sum of the lengths of its sides. Then, they have look at the other triangles and identify the ones that are the same type as the triangle they have drawn in the box. When they identify them, they have to circle them, count how many they are and write the number in the box under “Number:”.

Check the answers as a whole class activity. (10 min)

Step 5

Distribute Handout 5 to each student.

In Task 1, students have to determine the type of triangles according to the lengths of their sides.

Task 2 is linked to the elements of an isosceles triangle. It is necessary to determine which two sides of the triangle are equal and which side is different in length.

In Task 3, students measure the sides of the triangles, determine their type according to their sides lengths, and find their perimeters. (10 min)

Step 6

Divide the students in 3 groups. The members of the first group are the students who worked with equilateral triangles in Step 2, the second group members are the students with the isosceles triangles, and the third group members - those who worked with scalene triangles. Give each group the page with the corresponding type of triangle (Handout 6). Distribute one A3 size sheet of paper to each group. Students are asked to cut out and use the triangles to create a picture to represent a real-life situation; they can also draw some extra elements and color it. Each group chooses one or two of its members, who present their artistic work to the rest of the class. (20 min)

Reflection
  • 1. Ask the questions:
  1. Did you learn something useful today? What is it?
  2. Which activity did you like most?
  • The energizer Triangle or Circle.
  • The relaxing activity Triangle of friendship.
  • Step 4: connecting the dots and spotting the same type of triangles.
  • Step 6: artistic work.
  • 2. Provide a picture of a traffic lights to each student (Handout 7). Ask them to colour the light which indicates how they feel at the end of the lesson.
  • green stands for being satisfied with the completed work and having understood everything presented during the lesson;
  • yellow stands for not understanding some of the tasks and not particularly liking the lesson;
  • red stands for being dissatisfied with the lesson.

Introduction

Involving students in their laterality and location in space is a major challenge, which first requires them to experience locating themselves in relation to others, then in relation to space and objects. Recognising and identifying various spatial notions and then exploring the student's ability to orient themselves and act on the room space, progressively targeting the street, houses, buildings, entrances and exits, leading the student to be able to orient themselves and locate themselves independently.

Teaching and learning methods

Teaching and learning is a process based on concrete issues and situations that are close to the students. Learning by doing through effective manipulation of the material, facilitating awareness of what is being learnt. Co-operative and collaborative learning - work carried out in cooperation and collaboration in groups and pairs. New technologies as a way of learning/consolidating content.

Interdisciplinary connections

Maths - Developing an interest in maths and appreciating its role in the development of other sciences and areas of human and social activity.

Mother tongue- Select relevant information according to the objectives of listening and record them using different techniques. Speak clearly and articulate words appropriately.

Citizenship and Development - According to the citizenship education needs diagnosed by the school group/class - The need to know how to identify, orientate oneself and help orientate others is important for the social relationship process. 

Resource teacher or other specialists activities

All the steps in exploring the topic are understandable for students with specific needs but cognitive abilities. The lesson does not include lengthy written explanations. The role of the support or special education teacher is to help the students in the target group if they are unable to carry out any of the tasks or steps, or if they feel disorientated in understanding something that may be asked of them.

Identifying and manipulating and handling materials, taking part in games, exploring content by visualising images, etc. are usually well accepted and meet the interests and needs of most students.

New vocabulary

Localisation, orientation, spatial awareness;

Work Flow

1st step - Individual

The classroom must be organised with the desks in rows and columns, these should be numbered in the first row.

1,2,3,4...tape an A5-size piece of paper to the top left-hand corner of each row. (Appendix 1)

Start by involving the students in the space by asking each student individually (following the order in which they are seated) to name the classmate who is either in front of them, behind them, on their right or on their left...

Explore other spatial notions, referring to the place where the  materials or other equipment are in the room, etc. 

E.g. The teacher’s desk is on the right side of the room.

       

2nd step - Large group

Project the classroom plan with the tables placed in five different rows and five columns  on the interactive whiteboard. (Appendix 1).

Ask the class the following questions:

• Where is student A? In which row is he in?

•   Who is the student closest to the door?

•   Who is sitting in front of the teacher's desk?

•   Name a pupil who is sitting in the last row next to the window.

•   Name the student in the first row who is sitting in the fourth column.

•   Who is sitting next to a window, a noticeboard... (depending on what's in the room)

•   Where is the noticeboard in the room? If there are two blackboards, ask which one is on the right and which one is on the left (if they are next to each other); if not, formulate the question according to the layout of the blackboard(s).

•   In the first row, which student is furthest to the left, in the middle or to the right?

•   With the teacher facing the students, ask which is the teacher's right hand?

  • .../...

3rd step - In pairs 

Ask the students to keep on their desks only the pencil case or bag containing the pencils, eraser, sharpener, scissors…

According to the teacher's instructions, the students will place the named objects in the indicated positions. Every student has his / her own objects.

E.g:

Place the charcoal pencil in the top left-hand corner of your desk.

Place the scissors in the bottom right-hand corner of the table.

Place the eraser in the middle of the table

Place a coloured pencil in the top right-hand corner. 

You can continue this dynamic by asking the students to place a school book on the table, for example, and ask them to position the school materials in the case in relation to the book:

Eg:

Put a pen on top of the book...,

Put the eraser to the right of the book,

Put the charcoal pencil at the top of the book... at the bottom...,

Put a coloured pencil under the book.

4th step Large group

Playing with spin the wheel https://spinthewheel.io - free application to be prepared before the plan is realised.

The roulette wheel can be used in 2 different ways:

1st Possibility

The roulette wheel can be used with the names of the students that randomly are going to answer the teacher’s questions about the pictures on appendix 2 that the teacher will project.

E.g. Picture 1 - Where is the boy? He’s under the tree.

2nd possibility

Write instructions on the roulette wheel that the students must perform when they are called.  Here you can play a game with numbers to sort out the child to perform the task.

e.g. Each child has a class number (from 1 to 20). The teacher asks:

- How many students are there in this class?

 - 20
 - 20 minus 5 equals 15. Who is number 15?

- Number 15 - Go and sit next to the classmate immediately to your right.

Each child performs a task.

- Stand up and go to the partner you think is furthest away from you ...

- Get up and stand behind your chair.

- Head for the exit door, passing in front of colleague B

- Pass by, stand up and pass behind colleague Y and go to the teacher.

Introduction

What is division?

Learn that division makes it possible to divide or distribute elements of a set or unit into equal parts.

Involving students in the dynamics of division as a mathematical operation used to separate the elements of a set or unit into smaller sets or units, i.e. dividing a quantity into equal parts. Division makes it possible to solve various types of everyday situations, which is why it is so important to learn in order to apply it. Develop practical activities to consolidate learning.

Teaching and learning methods

Teaching and learning is a process based on concrete issues and situations that are close to the students. Learning by doing through effective manipulation of the material, facilitating awareness of what is being learnt. Co-operative and collaborative learning - work carried out in cooperation and collaboration in groups and pairs. New technologies are used  as a way of learning/consolidating content.

Interdisciplinary connections

Maths - Developing an interest in maths and appreciating its role in the development of other sciences and areas of human and social activity. (taken from Essential Learning - Basic Education)

Mother Tongue- Select relevant information according to the objectives of listening and record them using different techniques. Speak clearly and articulate words appropriately.

Citizenship and Development - In accordance with the citizenship education needs diagnosed by the school group/class - To help students experience and acquire skills and knowledge in various areas, particularly social, articulating knowledge of the importance of learning to share, distribute ...

Resource teacher or other specialists activities

All the steps in exploring the topic are understandable for students with specific needs but cognitive abilities. The lesson does not include lengthy written explanations. The role of the support or special education teacher is to help the students in the target group if they are unable to carry out any of the tasks or steps, or if they feel disorientated in understanding something that may be asked of them.

Identifying and manipulating and handling materials, taking part in games, exploring content by visualising images, etc. are usually well accepted and meet the interests and needs of most students.

New vocabulary

Dividing, distributing, dividing a quantity into equal parts, equitable sharing.

Work Flow

1st step – Large group.

Start by stating that division is a mathematical operation just like the others we have already learned, such as addition ( ), subtraction (-), multiplication (x) The symbol of division ÷ : which means to divide. Sharing is the same as separating, distributing or sharing. Engage students in a practical example.

2nd step – you should Help divide the class into EQUAL groups,

which can be 3, 4, 5..., taking into account the number of students in the class on the day of the activity. If the number is odd, the teacher immediately asks for an assistant to help confirm the number of groups formed and whether all the groups have the same number of students. This data is passed on to the board, where all the students in the class are drawn and the students have to find out how many there are.

3rd step – Group work

Ask students to leave on the table only the pencil case of one of their classmates in the group. Ask the students to distribute the pencils to everyone so that they all get the same number of pencils. Track how each group solves the challenge. Afterwards, ask each group to explain how they solved the challenge.

4th step – Pair work

Distribute Appendix 1 to each pair. Ask them to cut the fruits and make groups with each type of fruit. This material can be used in subsequent classes that address this topic or others.

5th step – Pair work

Distribute Appendix 2 to each pair, so the students can solve the exercises. They are going to use the cards with the fruits cut in step 4 to answer the questions about the division.

6th step – Large Group

Before leaving the class, students are  invited to make two groups comprising the same number of students (they have to find out how to do it). When the class finishes this task, the teacher explains that each group represents half of the class.

The student who has the role of teacher’s assistant can count the number of students in each group and say how many students belong to each group (comprise half of the class).

Reflection

Ask the students individually to refer to a learning activity that was most meaningful to them.

Relaxing Exercises senpower     19 - Massage ball

One ball is given to each participant and, following the rhythm of a soft music, they place the ball between their back and a wall. They bend their knees slightly to relax the legs and better place their back. Then they move their body from top to bottom and from right to left and vice versa, moving the ball around their back. When making movements of their body, they will notice some more tense (and sometimes painful) spots. When they notice this they should stop and stay quiet keeping their back against the wall, making the desired pressure and holding for a while.

Variation: Do not use the wall. Participants work in pairs and one holds 1 or 2 balls in their hands and makes the massage to the other and then they switch.

Objectives

Students will:

• update their knowledge of the measurement unit centimetre and its symbol cm;

• form an idea of the measurement unit for length decimetre and its symbol dm;

Introduction

In everyday life we often need to measure the distance between two points or the length, height or width of objects. This can be done in different ways. For example, we can use our hand span to determine the length of the sleeve of our favorite blouse. But will the result of the measurement be the same if it is expressed with your hand span compared to your father’s hand span? Most probably not. This is why, if you want to get an accurate result from the measurement of the length of the sleeve, no matter who does it, you need to use a different tool and a standardised unit of measurement for length. You already know the measuring unit for length centimetre. You can measure the length of segments using a ruler. Today, we will learn about other measuring tools and units of length that are suitable for measuring larger objects and longer distances.

Work Flow

1. For an introduction to the lesson, you can use various e-resources, such as https://www.youtube.com/watch?app=desktop&v=ftB5VU64yGA which are meant to demonstrate different handy tools for measuring length. You could have several students measure the length of one and the same object, e.g. the white board or a table, using different measures – hand span, cubit, a notebook, etc. Write the results on the board and compare them. Students will see that when the length of an object is measured making use of a non-standardised measuring unit (e.g. a notebook), there results are different and this is because some notebooks/ hand spans, etc. are bigger than others. This a practical way to come to the conclusion that we need to use uniform units of measurement for length. (5 min)

  1. Distribute Handout 1 to each student.

In task 1 students need to determine the length of the objects using a paper clip as a measurement unit.

In task 2 they have to determine the length of objects and identify the longest and the shortest ones.

In task 3 they have to measure the length of the segments using a ruler.

The teacher remembers them the correct placement of the ruler. (5 min)

3. Every student is provided with a coloured strip from Handout 2 and has to measure its length with a ruler. Students begin the measurement as the teacher signals launching the activity and raise their hands when they are ready. The teacher measures the time with a stopwatch and stops it when the last student is ready. The duration is recorded on the board.  (2 min)

4. Slide 3 of the presentation (Annex 3) shows the result of the measurement – the strip is 10 cm long. This is how the new measurement unit for length decimetre is introduced, as well as its symbol – dm.  (3 min)

5. Students receive Handout 4. The first 3 tasks are solved as a whole class activity.

In task 1 they have to determine which brush is 1 dm long.

In task 2 they have to measure the length of the segments and record them in centimeters and decimetres.

In task 3 they have to convert from centimeters to decimetres and vice versa.

The tasks are solved collectively with the whole class, and the corresponding comments are made. (5 min)

6. After completing the 3 tasks from Handout 4, students are asked to measure the length of their desk/table/chair or other suitable object in the classroom using the coloured strip from Handout 2. The teacher signals launching the activity and, similarly, measures (making use of a stopwatch) the time until the last student is ready. The time needed to measure the length using the coloured strip is recorded on the board. The two results (from activities 3 and 6) are compared and students come to the conclusion that measuring the length of larger objects using a 10 cm long strip takes significantly longer.

After that, the teacher demonstrates (using a tape measure or sewing tape) measuring the same object – this will take just a few seconds. The conclusion is that when measuring longer, taller, or wider objects, or longer distances, we need to use different tools, not the ruler we usually use in class.  (4 min)

7. Slide 4 of the presentation (Annex 2) introduces the unit of length metre and its symbol - m. Slide 5 shows some tools we use to measure the length in metres. (3 min)

8. Students work again with Handout 4 completing the remaining tasks.

In task 4, they have to convert from metres to decimetres and vice versa.

In task 5, they have to identify which is the most suitable tool to use in each case.

In task 6, students have to compare several objects and arrange them according to their height. The teacher can ask additional questions: Which object is taller than 1 m?, Which one is shorter than 1 m? etc.

The tasks are solved collectively with the whole class, and the corresponding comments are made. (5 min)

9. Divide students into several groups. Distribute Handout 5 to each group. Provide a couple of rulers and tape measures or sewing tapes for each group. Students step in the shoes of detectives looking for objects in the classroom which comply with the characteristics in the boxes. They walk round the classroom and measure the objects they see using the provided tools and record the name of the objects in the appropriate cell. Some boxes will stay  empty in case no object with the required characteristics is identified. After completing the task, each group chooses a representative, who communicates the results of the research to the class. (10 min)

7. Finally, the teacher makes a summary of the algorithm discussed in the lesson. (2 min)

Reflection

At the end of the lesson the teacher can ask and discuss the following questions with the class:

1. What is the most useful thing you learned today?

2. Which activity did you like most?

  • The energizer Find another seat;
  • The relaxing activity Massage ball;
  •  The detective task of searching for objects in the classroom.

Preparation

Materials Needed:

  •  printed ( Annex 1)
  • Drawing materials such as pencils, crayons, and markers
  • Chart paper
  • Printed activity sheets (Annex 2)
  • Scissors
  • Glue
Introduction

Begin the lesson by asking students if they know what symmetry means. Encourage them to share any ideas or examples they may have.

"Welcome, class! Today, we're going to embark on an exciting journey to explore the fascinating world of symmetry, where shapes come to life in perfect balance and harmony."

Teaching and learning methods

Direct Instruction: The teacher introduces the concept of symmetry through explanations, examples, and non-examples. Direct instruction is used to provide foundational knowledge to students.

Visual Aids: Visual aids such as shapes displayed on the board help students visualize symmetrical and asymmetrical shapes, reinforcing the concept through observation.

Hands-On Activities: Students engage in hands-on activities such as identifying symmetrical shapes, creating symmetrical designs, and completing symmetry worksheets. These activities promote active learning and allow students to apply their understanding of symmetry in various contexts.

Group Discussion: Throughout the lesson, students participate in group discussions to share their observations, reasoning, and discoveries regarding symmetry. Group discussions encourage peer-to-peer learning and help clarify misconceptions.

Modeling: The teacher demonstrates how to create symmetrical designs by folding paper and drawing on one side. Modeling allows students to observe the process firsthand and provides them with a clear example to follow.

Interdisciplinary connections

Art: The lesson incorporates elements of art through activities such as creating symmetrical designs. Students explore symmetry not only as a mathematical concept but also as a creative expression.

Resource teacher or other specialists activities

Providing Extra Time and Modified Assignments:

  • Allow extra time for completing tasks and offer simplified versions of worksheets if necessary.
New vocabulary

Symmetry: The quality of being made up of exactly similar parts facing each other or around an axis.

Symmetrical: Having balanced proportions; exhibiting symmetry.

Asymmetrical: Not having symmetry; lacking balanced proportions.

Line of Symmetry: A line that divides a shape into two equal parts, with each part being a mirror image of the other.

Axis: An imaginary line about which a shape or object is symmetrically arranged.

Mirror Image: The image produced by reflection in a mirror or other reflective surface

Work Flow

Warm-up Activity (5 minutes):

  1. Begin the lesson by asking students to sit in a circle.
  2. Next, play a quick game of "Mirror, Mirror" where students mimic each other's movements to reinforce the concept of symmetry.

Guided Learning Introduction (10 minutes):

1.Display a few symmetrical and asymmetrical shapes on the board.

2.Discuss the concept of symmetry, explaining that a shape is symmetrical if it can be divided into two equal halves that mirror each other.

  1. Review key vocabulary such as "symmetry," "symmetrical," "asymmetrical," and "line of symmetry."
    • Symmetry: “Symmetry means balance or harmony. When we say something has symmetry, it means one side looks like a mirror image of the other side.”
    • Symmetrical: “A shape is symmetrical if it can be divided into two identical parts that are mirror images of each other. For example, a square is symmetrical because if you fold it along its middle, both halves match perfectly.”
    • Asymmetrical: “A shape is asymmetrical if it cannot be divided into two identical parts. For example, a triangle that does not have equal sides is asymmetrical because it doesn't look the same on both sides.”
    • Line of Symmetry: “The line of symmetry is an imaginary line where you could fold the shape, and both halves would match exactly. It's like drawing a line through the middle of a shape to show that both sides are the same.”
  2. Give examples and non-examples to reinforce the concept by drawing on board.
  3. Show them a few objects that exhibit symmetry (Annex 1) (e.g., a square, a circle).
  4. Ask students to identify the line of symmetry in each object.

Activity 1: Creating Symmetrical Shapes (10 minutes):

1.Provide students with a blank sheet of paper and ask them to fold it in half.

2.Demonstrate how to create a symmetrical design by drawing on one side and then folding the paper to create a mirror image.

3.Encourage students to experiment with different shapes and designs.

4.Circulate around the room to provide assistance and feedback.

Activity 2: Symmetry Worksheets (10 minutes):

1.Hand out symmetry worksheets to students (Annex 2).

2.These worksheets will include cutting out and coloring symmetrical drawings, and identifying lines of symmetry.

3.Allow students to work individually or in pairs.

4.Review the worksheets together as a class, discussing any misconceptions or challenges.

Closure (5 minutes):

  1. Gather students together and review the key concepts covered in the lesson.
  2. Ask students to share one thing they learned about symmetry today.
  3. Summarize the lesson by emphasizing the importance of symmetry in everyday objects and shapes.
Reflection

Objective: To reflect on learning about symmetrical shapes.

Procedure:

  1. Circle Time): Gather students in a circle.

Lion’s breath is a playful way to release and relax into more peaceful feelings. The trainer tells students that they are going to do a breath called the lion’s breath in order to let go of feelings or thoughts we no longer want. This breath is very helpful in getting those ideas out of us and pushing them far away.

Instructions

  • Imagine that you are a mighty lion. You have a giant roar!
  • Sit on your heels and sit up tall like a mighty, proud, lion. Get ready to let your roar go!
  • Think of a feeling or a thought that you would like to let go. Squeeze your hands into fists, holding tight and thinking of that feeling or thought.
  • Take a deep breath in and let your roar out, stick out your tongue at the same, stretch your arms out wide in front of you and open your hands wide, roaring out the feeling or thought and letting it go.
    • Repeat.

It is like the game "telephone" but instead of passing a word or sentence around the group, participants pass a facial expression.
The group forms a circle with everyone having their eyes closed, except the person who is passing the "face" in the first place. The passer will tap the shoulder of the person next to her/him, that person will open her/his eyes to receive the face. She/He will then tap the shoulder of the person next to her/him and pass the face along. Once participants have passed the face they may keep their eyes open to watch it move around the group. At the end, the original passer receives the face from the last person in the group and then shows what the original face was.

Introduction

Quite often in our daily life we share different things with members of family or friends - the chocolate with a sibling, the pizza or the bill in the restaurant with friends, etc. In cases like that, we divide a whole into several smaller parts. And because we want this division to be fair, the parts must be equal, right? In this lesson, you will learn about dividing a whole in 2, 3, 4, or 10 equal parts.

Teaching and learning methods

Learning in small steps

Break instructions down into smaller parts

A tenth

Work Flow
  1. Start the lesson describing the following situation: Imagine you bought a pizza for lunch, but your friend asked you to share it with him. You are two persons all together so you have to divide the pizza into 2 pieces. You can do it in different ways - cut the pizza into 2 pieces, one of which is bigger than the first, or divide it into 2 equal pieces. The second way is definitely fairer, right?

Use animations and video clips to show possible ways of dividing a whole into parts.

Examples: https://www.facebook.com/CretaClass/videos/dividing-a-pizza-into-equal-parts/1085002548991803/?locale=zh_CN

https://www.youtube.com/watch?v=eEsy0igg4XE

https://www.nagwa.com/en/videos/686103468703/

Another option is to use the images from Handout 1. Print the handout for each student so that they can compare the different ways of dividing the pizza. Ask students to cut the pictures along the white line, compare the two parts, and find out in which case they are the same. (5 min.)

  1. 2. Distribute the cut-out figures from Handout 2 to each desk/table. Students work in couples. Ask them to look carefully at the figures, determine whether they are divided into equal parts or not, and place them in the corresponding column of the table. (5 min.)
  2. Firstly, show the square from handout 3, fig. 1.; then, fold it in the middle so that you get 2 identical parts. Show the students that the two parts match perfectly. Next, unfold the square and trace the line where it was folded with a marker. The square is now divided into 2 equal parts. (3 min.)
  3. Play the presentation on the screen. Ask students to determine how many equal parts each figure is divided into. Then, aske them how many of the parts of each figure are colored. Read the names of the colored parts of each figure introducing the terms a half,  a third, a quarter, and a tenth. (3 min.)
  4. Explain and show to the students that dividing in equal parts can be done in different ways but the equal parts obtained by division have the same size and the same shape. Use handout 3, fig. 2 and fig. 3 to show that the square can be divided into halves in different ways. Fig. 2 and fig. 3 are two identical squares, which are divided into halves that are of a different shape. (3 min.)
  5. Distribute the cards from handout 5 to each desk/table. Students work in pairs. Ask them to color the answer that indicates what part of the shape is coloured. (5 min.)
  6. Continue working in pairs with the cards from handout 6. Provide one set of the cards and 11 paper clips for each pair. Students have to read the problem on each card and identify which shapes comply with the condition and place a paper clip on them. (5 min.)
  7. 8. Ask students to coloуr the indicated part in each of the figures in handout 7. (5 min.)
  8. Divide the students into groups of 4. Give each group a package of plasticine and a box of toothpicks. The task is to construct different geometric shapes with the toothpicks by fixing them together with plasticine. After constructing the figure, they have to divide it into equal parts following the instructions of the teacher. Each group gets a different tasks, e.g. Group 1 has to construct patterns of squares and divide them into 3 equal parts (in different ways); Group 2 has to create patterns of rectangles and divide them into 2 equal parts (in different ways), etc. One of the groups could be assigned the task to create a model of a circle (made of plasticine) and the division into equal parts is to be done with the help of the toothpicks. (15 min.)
  9. Present some examples from children's everyday life that illustrate the division of a whole into equal parts. You may use the presentation, add other examples, or prepare a similar presentation. Have students add their own examples at the end of the presentation. (5 min.)
  10. Division of a whole in parts in fine arts.

Present the paintings of the famous artist Wassily Kandinsky. Ask students to look carefully at the paintings and spot the parts in which there is division into parts (1) and division into equal parts (2). (5 min.)

Optional task

Prepare a similar picture in which there are figures divided into parts, or use handout 10. Ask students to colour the picture of their choice, giving them freedom which parts to colour and in what colour.

       12. Finish the lesson with e-games: Students play the games on their mobile devices or the teacher opens a game on the screen and volunteer students take turns to come to the front and play. (10 min)

Relaxing Exercises senpower     23 - Guess who? Draw your partner

With the Avatars distributed randomly on a table, the students are invited to get one of their classmates' Avatars, which they have to complete, trying to understand whose half of the Avatar they have to complete and silently draw the missing half to the sound of a calm song chosen by the leader.  As the students finish, they go to a board and place the completed Avatar with reusable, malleable white adhesive putty. The whole class observe and the challenge is to try to guess to whom the avatars belong to.

Objectives

In the end of the lesson students should be able to:

  • observe  different figures and shapes around us;
  • recognise in nature, most living things have some symmetrical element;
  • distinguish that all figures with reflection symmetry have an axis (reflection axis) that divides them into two equal parts;
  • verify that reflection allows them to move a figure without changing its original shape;
Preparation

Material:

  • Students’ avatar on A4 sheets;
  • Printed images;
  • Mirror or metallized cardboard A5 size; 
  • Sheets of squared paper;
  • Sheets of A3 white paper
  • Sheets of A4 coloured paper;
  • Computer and speakers for sound production (music accompanying the game).
  • Individual computers;
  • Re-usable, malleable white adhesive mass
  • Coloured inks;
  • Scratching material;
  • Scissors.

Lesson pre-preparation

Create each student's Avatar from the following free link. https://avatarmaker.com/

Students can either create their own Avatar during a computer activity, or during a study support moment, or any other that the teacher considers appropriate. Or the teacher may create each student's Avatar, making them available ready to be used.

Preparing the lesson

The room should be with the tables and chairs shifted close to the walls, so that there can be plenty space to make a dynamic game. Once the game is finished, the students help putting the tables and chairs back in their places.

Meanwhile, there should be a table with all the necessary materials to be used during the lesson.

Students' individual computers should be on their desks and already connected to the internet.

A board where Avatars can be placed, is available for students to display their works.

Introduction

Symmetry and reflection should be approached from concrete situations. Teachers should integrate students’ experiences, use familiar  or daily life contact materials, enabling them to learn the content by, observing, experiencing and discovering  the contents in a  natural way by:

  • observing the nature around us and verifying that living beings are mostly formed by symmetrical elements;
  • recognising that the line on which a fold or a mirror is placed is called the symmetry axis of that figure: it divides the figure in half so that one half of the image  is the reflection of the other half;
  • distinguishing that a shape is divided into two equal parts, which means that it reproduces its image;
  • checking out that a figure does not change when reflected in a mirror, water, etc.
Teaching and learning methods

Considering that the teaching of reflection and symmetry can be approached using concrete material, we will have to invest in:

  • Learning based on questions/situations close to the students;
  • Learning by effective manipulation of material, facilitating awareness of what is being learned;
  • Cooperative and collaborative learning - Work developed in cooperation and collaboration in groups and pairs;
  • New technologies as a way of learning/consolidating content.
Interdisciplinary connections

Portuguese Language – Understamding the gist of oral discourse on familiar topics; use appropriate language to express knowledge and present narratives.

Natural Studies - Knowing how to ask questions, make hypotheses, make inferences, check results and know how to communicate them, recognising how knowledge is built up. Observation of living things to find points of symmetry.

Artistic Education - Visual Arts - Drawing each student's missing half of his/her face, symmetry painting and cut out folding. 

Physical Education - The mirror game.

Resource teacher or other specialists activities

All steps of the topic development must be understood for SEN students with cognitive abilities. The lesson does not include long written explanations. The role of the support or special education teacher is to help students in the target group if they are unable to complete any of the tasks or steps of the lesson, or feel confused in understanding something that may be required.

New vocabulary

Symmetry, reflection and axis.

Work Flow

1st STEP

With the room organised again with tables and chairs in their places. The teacher starts the lesson by introducing the topic, asking the students if they have any idea what the words symmetry and reflection mean. 

For students to understand better the concept of symmetry, the teacher provides printed images (Annex A) in individual folder) and asks students to fold them so that the two parts coincide leading students to understand that the 'fold' is the axis of symmetry.

2nd STEP

In small groups of four, students are asked to collect and identify symmetrical objects/materials/figures existing in the classroom.   According to the size of the materials, students are due to take the smaller ones to their working station while they try to identify and explain the larger ones with the teacher’s help. Learners should identify where the axis of symmetry of each object/figure is, and using their imagination students should figure out what would happen if a certain material is folded in half.

3rd STEP

Observing the symmetry of figures using a mirror.

In pairs, students are provided with a sheet of squared paper with only one symmetry axis dividing the sheet in half (Appendix B).  The teacher asks each student to draw with charcoal pencil or black pen, without filling or painting, part of a figure they wish to draw, only on one side, left or right in relation to the axis.                                                                  

4th STEP

After distributing mirrors to students, the teacher asks the learners to place the mirror on the axis of reflection. Afterwards, the students observe the reflection of the figure before it is completely drawn, leading students to realise that the missing part of the drawing is reflected in the mirror and that the mirror acts as an 'axis of symmetry'.

5th STEP

Each student exchanges with their peers the drawing they made in the previous task and tries to complete the missing half of the sheet, respecting the used squares.

The principle of mutual help should always be present.

6th STEP

The teacher challenges the students again. This time they have to work in pairs, to search for a picture on the computer, which can be: a photograph, a drawing a painting, a figure, a landscape... preferably placed vertically and occupying half the screen:

1- Students should be asked to place the mirror, on the axis of reflection and observe in the mirror the reflection of the full image.

2- Each pair should use the computer to discover the reflection axes in other symmetrical images.

7th STEP

Working on Arts (Artisitic Education Activity). 

Two options:

  • Symmetric Painting - coloured paints, A3 size white sheet.
    The students fold the sheet in half and drop drops of paint next to the fold. They close the sheet, spread the paint with their hands from the axis (fold) outwards, open the sheet and the result is a symmetrical image. Example in Annex B
  • Symmetrical folding - Coloured sheets of paper that the students fold in half, drawing whatever they want. Using scissors, the folded coloured sheets can be cut out, so that when students open the sheet, the cuts-out appears in duplicate.  Example attached. Example in Annex C
Reflection

Guided discussion:

What was the most important thing you think you have learnt today?

What was the activity you enjoyed most?

  • Extra Activity – the drawing of half of a colleague's avatar;
  • Group dynamics - Mirror game;
  • Activities carried out in small groups;
  • Activities done in pairs;
  • Research and activities on the computer;
  • Symmetry painting and symmetry drawing and cutting activities
Notes

Extra Activity:

With the Avatars distributed randomly on a table, the students are invited to get one of their classmates' Avatars, which they have to complete, trying to understand whose half of the Avatar they have to complete and silently draw the missing half to the sound of a calm song chosen by the leader.  As the students finish, they go to a board and place the completed Avatar with reusable, malleable white adhesive putty. The whole class observe and the challenge is to try to guess to whom the avatars belong to.

  • papers and crayons, scissors, primary colors of paint (red, blue, yellow); Paintbrushes and water cups

Preparation

  • Visual aids displaying whole, half, and quarter fractions. (Annex 7)
  • Familiarize yourself with the different ways to represent fractions visually.

You can use different methods: You can watch the video to learn one of  these methods.

Manipulatives: Virtual manipulatives like blocks or tiles can be used to visually display fractions by grouping and arranging them accordingly.( https://youtu.be/hUEkmcTeIos)

  • Print annexes 3,4,5,6 for each students to use in the class.
  • Use Annex 1 and Annex 2 as powerpoint presentations.
Introduction

Begin the lesson by asking students if they have encountered fractions before or not and after the answers you can give an easy example : Tell the students the following case:

If a family consists of 4 people and there is only one apple in the house but everybody wants to eat a piece of the apple, how can we share it between the family members equally? The solution is to cut the apple in 2 equal parts, and then cut each of the pieces in 2, so that we have 4 equal pieces. These part of the whole apple we call quarters; and a quarter is a fraction.

Teaching and learning methods
  • Direct Instruction: Explain the concept of fractions, emphasizing whole, half, and quarter fractions. Use visual aids to demonstrate each concept.
  • Group Activities: Divide the students into groups and provide each group with fraction manipulatives. Instruct them to explore and represent whole, half, and quarter fractions using the manipulatives.
  • Class Discussion: Engage the students in a discussion about the different ways to represent fractions and how they can apply this knowledge in everyday situations.
Interdisciplinary connections

Connect fractions to art by discussing how artists use proportions and ratios in their work. Color Mixing Ratios: In painting, artists use fractions and ratios when mixing colors to achieve the desired hue and shade. The right blend of colors can enhance the overall visual impact of the artwork

Whole, Half, Quarter, Fraction

Work Flow
  1. Start with a brief discussion on what fractions are and their relevance in everyday life.
  2. Show visual aids and explain whole, half, and quarter fractions. (Annex 7)
  3. Show Annex 1 and ask what does each picture represent? (whole, half or quarter)
  4. Show Annex 2 and ask what the picture on slide 1 represents? Show slide 2 and ask if  the image represents a half or not. Explain to students that only when the two parts are equal we call them halves.
  5. Engage students in group activities with circle fraction manipulatives. They will make whole, half and quarter with them.

-Gather all the students together and introduce the concept of fractions.

-Explain that fractions represent parts of a whole.

- Divide the students into three groups. Aim for diverse groupings to encourage collaboration and teamwork.

- Distribute the fraction manipulatives to each group and briefly explain how to use them.

-each student from group 1 receives a circle of different colour; instruct students to cut the circle into four equal pieces by folding it; when students are ready with the cuts, all pieces are put together;

 - each student from group 2 receives a circle of different colour; instruct group 2 students to cut their circles into eight equal pieces; when students are ready with the cuts, all pieces are put together;

 - each student from group 3 receives a circle of different colour; instruct students to cut the circle into 16 equal pieces; when students are ready with the cuts, all pieces are put together.

Task 1: Show them how to represent a whole using the manipulatives. Instruct the groups to work together to create a whole using the fraction manipulatives they have prepared. They can use different combinations of fractions to represent a whole.

Task 2: After the groups have successfully created a whole, ask them to find different ways to represent halves using the fraction manipulatives. They must use their true size and colour pieces of manipulatives.

- Once they have grasped halves, challenge the groups to represent quarters using the fraction manipulatives.

  1. Use Annex 6. Ask students to color the fruits blue if they are whole, and yellow if they are half.

Exploring Color Ratios

-Provide each student with a white sheet of paper  and the primary colors of paint.

-Instruct them to choose a primary color and create a color gradient by adding varying amounts of white paint to that color.

-Encourage students to experiment with different ratios and observe how the color changes as they add more or less white paint.

  1. Final wrap up and summary of new knowledge.
  1. Make use of  annexes 3, 4 and 5. Deliver the worksheets you have printed before the lesson and have students work on their own or in pairs; check the anwers as a whole class activity.
  2.  Ask all student come to the front and stand in a line.

Task 1: Students have to find out how many they are. İn case the number is odd, the teacher asks one student to be his assistant, so that the numebr of students is even.

Task 2: Students are asked to split in 2 equal groups (they have to find out a way how to do it). When the task is completed the teacher explaines that each group is half of the class. The student playing the role of an assistant teacher (if any) could count the number of students in each group and tell the class how many students comprise a half.

Task 3:

Preparation: Students are instructed to come all together again. The teacher makes sure that the number divides by 4. İf this is not the case, e.g. there are 27 students in the class, 3 students are asked to come to the teacher and assist him/her during the activity.

Task 4: Students are asked to split in 4 groups with equal number of students in each group. Similarly, the teacher explaines that each group is a quarter of the class.

Reflection
  • Ask students to share their favorite part of the lesson and what they found most challenging.
  • Review the main concepts of whole, half, and quarter fractions.
Notes

Encourage peer-to-peer interactions during group activities to foster collaborative learning.

Developed by Prosveta-Sofia Foundation
Grade 3
Duration 60
Energizers senpower     20 - Chief of clan

Everyone stands in a circle. One participant closes his/her eyes or steps out of the room. He/She will have to guess who is the chief of the clan. One participant volunteers to be the secret Chief (quietly, so the "guesser" can't hear anything). The chief begins an action such as snapping fingers, patting the tummy, or slapping knees, and everyone in the circle imitates him/her.  The guesser returns to the room and tries to figure out who the chief is. As the guesser looks around, the chief changes the action avoiding being detected.

Relaxing Exercises senpower     20 - Holding legs

Participants work in pairs. And you can put a quiet and relaxing music (or sounds like water falling down, sea waves, etc.). 

Half of the participants are asked to lie down face up, eyes closed, with their left leg extended on the floor and their right leg elevated. Another participant stands up and loops a towel around the heel of the other’s right foot and holds the ends of the towel in his/her hands, and makes soft and gentle movements (upwards and downwards, and sidewards) while the other totally relaxes his/her leg. Then they repeat the same process with the left leg. Then the participants switch roles.

Objectives

Students will:

• become familiar with a new type of word problems;

• form skills for solving text problems of addition and subtraction – inverse variation;

• consolidate their skills for addition and subtraction of numbers up to 1000 with carrying;

• understand better the practical application of mathematics.

Preparation

Materials

Colour pencils

Equipment

Laptop and projector

Preparation

1. Print out Handout 1 in several copies and cut the 3 cards with problems. Each student should receive one card.

2. Print Handout 3 for each student.

3. Print Handout 4 for each student.

4. Print Handout 5 and cut the traffic lights separately so that students can provide their feedback.

Introduction

You already know that some problems may be expressed in words not in numbers. Word problems show very well the application of mathematics in our daily life. To solve a word problem we need to decide which arithmetic operation or operations we need to perform to solve it. There are some specific words that play the role of hints telling us what to do - add, subtract, multiply or divide numbers. You know that when the problem reads "... more than" we have to add up the numbers to find the answer, whereas when the problem reads "... less than" – we subtract the numbers. But is that always the case? Definitely not! In today's lesson, we will discuss cases when this rule is not to be applied. You will get acquainted with a new type of word problems.

Teaching and learning methods

Resource teacher or other specialists activities

Word problems are difficult for all students, special needs students included. It is important to pay specific attention to presenting the contents of the problems as diagrams so that the students understand the link between the provided information and the resulting arithmetic operations.

New vocabulary

Word problems - inverse variation

Work Flow

1. The lesson can begin with tasks meant to update students' knowledge and skills of addition and subtraction of numbers up to 1000 with carrying. For this purpose, the teacher can use the task cards from Handout 1 or various online resources such as https://wordwall.net/resource/70887109. (5 min)

  1. The teacher opens the presentation from Annex 2. Student do the problem from slide 2. They know how to solve this type of problems – firstly, they have to make the diagram, and then – write the solution and come up with the answer. The teacher gives the students time to solve the problem independently. After that slide 3 is played with the texts of the two word problems. Students volunteer to read the texts of the two problems and the available information is compared element by element. The teacher listens to the students' comments, and finally, summarizes the similarities and differences in the provided information and the questions of the two problems. Then, he/she opens the diagram and the solution of the problems. The final conclusion is that the problem is the same, but it is worded in two different ways - in the first case it is a word problem in direct form, and in the second one – an inverse variation of the same problem. (10 min)

3. The teacher distributes Handout 3 to all students. They do the problems one by one. Firstly, they have a minute to do a problem, and then, its solution (with the relevant comments) is written and presented to the class. (10 min)

4. The teacher distributes Handout 4 to all students.

In task 1 students need to word the problems in a different way, so that they are in direct form. They have to make the diagrams and solve the problems.  

In task 2 students have to draw the diagram and solve the problem.

In task 3 students have to write the text in abbreviated format and solve the problem.  (10 min)

  7. Finally, the teacher sums up the most important difference between the two variations of word problems – the inverse one, presented in the lesson, and the direct one. (2 min)

Reflection

Provide a picture of a traffic lights to each student (Handout 5). Ask them to colour the light which indicates how they feel at the end of the lesson.

  • green stands for being satisfied with the completed work and having understood everything presented during the lesson;
  • yellow stands for not understanding some of the tasks and not particularly liking the lesson;
  • red stands for being dissatisfied with the lesson and not understanding the new type of problems.

Developed by IPSantarem - Bento Cavadas e Nelson Mestrinho
Grade 3
Duration 3h15
Energizers senpower     46 - Movement

Ask the students to lie down on the floor (on their backs or tummies) and tell them to demonstrate the sliding movement.

Figure 1. Illustration of the sliding movement


 

Some questions for discussion:

  • How would you describe the slide?

  • What changes when you slide?

Now, ask the children to lie down on the floor again and give their interpretation of the flipping movement (in a turn the pupils move from back to tummy or from tummy to back).

Figure 2. Illustration of the flipping movement

Some questions for discussion:

  • How would you describe the flip?

  • What changes when you flip?

Finally, ask the pupils to lie down on the floor and demonstrate the turning movement.

Figure 3. Illustration of the turning movement

Some questions for discussion:

  • If turning your back to your tummy is a flip and not a turn, what is turning like?

  • What changes and what remains the same when you turn?

  • Is the body pointing in the same direction before and after turning?

Students should be encouraged to use their own words to describe and characterize the different movements.

Moves like sliding, flipping and turning constitute rigid motion. They are motions that do not distort shape. Picking something up and moving it around for instance is a rigid motion, but stretching or warping it is not. These intuitive experiments are an excellent way to introduce more advanced geometric concepts, such as translation, reflection and rotation, as fundamental types of isometric transformations. In this lesson, we shall focus on the idea of rotation.

Relaxing Exercises senpower     41 - Puppets movements

Students sit in a circle on the floor and freely illustrate and discuss the different movements of sliding, flipping and turning with puppets.

Objectives

Students will:

  • Develop an understanding of transformational geometry as related with the study of motion.

  • Obtain the image of a simple plane figure by rotation, with the centre at a point and rotation amplitude of quarter-turns or half-turns, clockwise or anti-clockwise.

  • Consider isometric transformations as tools for analysing the reality around them, providing opportunities to recognise the relevance of geometry in the creation and construction of objects in different contexts.

  • Develop both self-confidence and social skills.

  • Build a positive attitude towards mathematics.

Preparation

Materials:

  • A1 or A2 size color construction paper (several colors)

  • Scissors

  • Rulers

  • Glue

  • Blank paper

  • Graph paper

  • Magnetic White Board

  • Magnets

Introduction

Geometry is a cornerstone subject in school mathematics, both because of its undeniable importance for understanding the space around us and because of its unavoidable historical relevance. Geometric transformations add a perspective of movement to the traditional methods of elementary geometry, and it makes perfect sense to study them from the first years of school. With this activity, students will have the opportunity, starting from an everyday context, to explore the notions associated with the concept of rotation in the plane, in its simplest forms (quarter-turn and half-turn rotations), while at the same time promoting their sense of aesthetics and developing their fine motor skills.

Teaching and learning methods

Exploratory learning from real-life situations.

Interdisciplinary connections

Language – oral and visual communication.

Arts – Construction and identification of geometric regularity in patterns 

Culture

Resource teacher or other specialists activities

Almost all the steps of the lesson are comprehensible to most special needs students who have well-preserved cognitive abilities. The lesson does not comprise written explanations, and the long instructions, which are difficult for the target group’s students (TGSt), are not many.

The role of the special needs teacher or the assistant teacher is to help TGSt in case they are not able to cope with some of the tasks or steps.

Work Flow

Phase 1: Presenting the context

A quilt is a multi-layered textile, traditionally composed of two or more layers of fabric or fiber. A single piece of fabric can be used for the top of a quilt, but in many cases the top is created from smaller fabric pieces joined, or patchwork, sometimes using scrap pieces of fabric. The pattern and color of these pieces creates the design, and many of them are built as repetitive geometric patterns.

Check on some exemples of quilt pattern traditions from aroud the world:

https://www.marthastewart.com/7836632/traditional-quilts-around-the-world

https://www.internationalquiltmuseum.org/

The teacher may show to pupils some local traditional pattern quilts, and discuss about the decorative and utilitarian use of quilts (like bedding, table topping,...) and the process quilting (sustainability by reduction of textile waste, an art form and an hobby,...).

If possible, the teacher shows a quilt to students and discuss how the quilt is
assembled. Teacher may ask students to describe patterns in the quilt.

10 minutes

Phase 2: Creating a quilt square

In this phase, teacher shows how to create a paper quilt square:

Cut a red 30 cm x 30 cm sheet of construction paper along its diagonals to create four congruent triangles.

Cut a yellow 30 cm x 30 cm sheet of construction paper the same way.

Glue one yellow triangle and one red triangle onto a blue 30 cm x 30 cm piece of construction paper as shown below:

The teacher needs to have another three copies of this design for steps ahead.Then, the teacher shows students other possible quilt square designs that he/she made previously from construction paper. Some examples that one may consider are: 

Teacher discuss with pupils how the pieces of construction paper are glued together to create each design.  

 

Organized in pairs, children now can draw on graph paper their own simple design or copy one design of their choice (one design for each pair). Next, the teacher tells pupils that they will construct four identical quilt squares using construction paper, following their own design as drawn.

 

On this stage of the work, teacher should:

- Check to ensure that students have drawn a simple design.

- Allow children to collect the materials needed to create their four squares (10 cm x 10 cm sheets of coloured construction paper, scissors, glue).

- Monitor pupils’ work and collaboration as they build their quilt squares, assisting them, if necessary, to make identical squares.

50 minutes

 

Phase 3: Exploring Rotations

When students have finished making their paper quilt squares, the teacher begins by drawing vertical and horizontal axes on the board.

Then, the teacher fixes (with tape or magnets) one of the quilt squares in the upper left quadrant on the board.

Teacher now holds a second quilt square directly superimposed the fixed square. Then, he/she asks the students, “How could I turn this quilt square onto the next (upper right) section?”. A volunteer student can show how to perform the rotation. Then, this second quilt square can be fixed in the upper right quadrant.


It is essential to recognise that, during rotation, there is a point on the square that remains fixed in relation to the movement - the centre of rotation - and the movement can be carried out while placing a finger at the center of rotation, on the vertex of the square positioned at the point where the axes intersect (marked in the image above). 

 

Now the teacher ask students, “Why would we call this rotation a quarter turn?”, connecting the quarter turn to the movement of the minute hand on a clock from the upright position to the quarterpast-the-hour position. Then, he/she records “Quarter Turn” next to the square.


 
At this point, the teacher can ask students, "What if instead of turning clockwise we turned anti-clockwise? Where would the square be?" Holding a third quilt square directly on top of the original one, another volunteer student can show how to perform this new rotation, a quarter turn anti-clockwise, keeping the same center of rotation as before. This third quilt square will be fixed in the lower left quadrant, with the corresponding record “Quarter-turn anti-clockwise”, also completing the first record as “Quarter-turn clockwise”.
To finish the pattern, after superimposing a fourth square on the initial square, the teacher asks a student to turn it round half turn. The quilt square will then occupy the bottom right-hand quadrant.

The teacher can also ask the student if the direction of rotation makes a difference (clockwise or anti-clockwise). At this stage it should be clear that the result of a half-turn is always the same regardless of whether it is taken in the forward or reverse direction. 

Students can be asked to describe the result of a full turn, to conclude that after a complete rotation the square returns to its original position and record “full turn” next to the original square.

The teacher can invite other students to demonstrate quarter turns (both clockwise and anti-clockwise).

40 minutes

 

Phase 4: Students’ quilt patterns

In this phase, each pair of students will build their quilt pattern using the quilt squares they built previously and using the process described above, using rotations. Each pair will glue their four quilt squares on a blank sheet of paper, to form the pattern.

It's up to the teacher to supervise each pair's work, making sure that the process is correctly implemented and that all groups present a quilt pattern formed from both quarter-turn rotations (clockwise and anti-clockwise directions), as well as half-turn rotation. At the end, the teacher collects the work of all the pairs and, with the help of the students, builds an exhibition so that everyone can enjoy the diversity of patterns constructed, as well as assessing the correctness of the work carried out by the different pairs. 

50 minutes

Reflection

Pairs of students are asked to explain the construction of their pattern. Some questions to ask might be:

  • What strategy did you use to make sure you rotated the quilt squares correctly?

  • What shapes or patterns do you see in your quilt design?

  • Do you know any examples of rotations in real life? 

Teacher can provide some (e. g. a car making a left or right turn) and ask students to describe the rotation (is it a quarter turn, a half turn or a other type of turn?)

Introduction

In our daily lives, we are constantly in contact with the presence of maths, both in our homes and outside. The ability to understand this relationship is extremely important in the development of all students. Students need to understand and use mathematical knowledge fluently (according to their age level), meaningfully and in a variety of situations. Mathematical knowledge is a fundamental tool to mobilise when working in mathematics and when interacting with other areas of knowledge, as well as the ability to create and solve problems in a variety of contexts, both mathematical and otherwise.

Introduction

Knowledge of money, and the many everyday situations in which it is used, is an extremely important factor in students' learning journey, as it is learning that prepares them for life.

It should be emphasised that students' mathematical experience is based on tasks, and it is essential that these are powerful and challenging in order to captivate students and boost their learning. It is important to consider tasks of a different nature, selected/adapted or created according to the objectives to be achieved. In this context, there are proposals such as creating situations in the classroom that depict people's everyday lives. For example, a "shopping trip".

Students need to see mathematics as a means of understanding and modelling situations in different contexts, and making informed and reasoned decisions, particularly with regard to the importance of money for purchasing goods and distinguishing between basic necessities and superfluous goods.

Teaching and learning methods

  • Integration of students' daily life experiences into the learning and knowledge process;
  • Learning based on concrete questions/situations that are close to the students;
  • Learning through the effective manipulation of material, facilitating awareness of what is being learnt;
  • Co-operative and collaborative learning - Work carried out in cooperation and collaboration in groups and pairs;

The teacher places the products "for sale" on a table. In front of each product, he places a card with the price. (Photos with products and prices (Appendix1)

2nd step - In pairs

Give each pair a record sheet (Appendix2)

Each student takes the notes and coins they drew and cut out in Visual Arts class. Together they count the "money" they have and record the amount on the sheet.

3rd step - In pairs

Students make a shopping list based on the money they have and the products on display, and make the calculations to find out how much money they have spent and how much money they have left.

4th step - Pair / Collective

Each pair of students presents to the class what they bought, how much they spent and the money left over, justifying their choices.

5th step - Collective

The teacher involves the students in a guided discussion about their shopping choices, bearing in mind that there are goods that are essential to us and others that are superfluous and that money management must take these assumptions into account.

Teacher tells the group that they should follow instructions when he/she starts the instruction by saying “Simon says...”. If the teacher does not begin the instructions with the words “Simon says”, then the group should not follow the instructions! The teacher begins by saying something like “Simon says clap your hands” while clapping their hands. The participants follow. The teacher speeds up the actions, always saying “Simon says” first. After a short while, the “Simon says” is omitted. Those participants who do follow the instructions anyway are ‘out’ of the game. The game can be continued for as long as it remains fun.

Relaxing Exercises senpower     15 - Moving like a toy

The teacher uses a magic word to change the students into many string-loaded (wind-up) toys. At the teacher’s signal, the toys start to move across the class, as many robots, to get their sits. They have to move more quickly at the beginning and then gradually more and more slowly, because their charge is finishing. Some of them will be frozen in the middle of the room, and the teacher has to give their cranks one more turn to help them reach their seats

Objectives

Students will:

  • understand the concept of division as equal sharing;
  • solve basic division problems;
  • apply division to solve word problems;
  • practice division through interactive activities.
Preparation

Required materials and print-outs:

  • Whiteboard and markers
  • Worksheets (Annex 1: Division problems, Annex 2: Word problems, Annex 3: Cut-and-Paste activity)
  • Counters or small objects (e.g., beans, buttons)
  • Scissors, glue, and paper
Introduction

  "Good morning, class! Today, we are going to learn about division. Division is a way of sharing equally."

  "When we divide, we split a number into equal parts. Can anyone tell me what we call the numbers we use in division? The number we are dividing is called the dividend, the number we are dividing by is called the divisor, and the answer is called the quotient."

  "Let’s start with a simple example. Imagine you have 12 cookies and you want to share them equally with 3 friends. How many cookies will each friend get? Let's write this on the board: 12 ÷ 3 = ?"

  "To solve this, we divide 12 cookies by 3 friends. We can think of it as making 3 equal groups. Let's  draw groups on the board

  "So, if we put 12 cookies into 3 equal groups, each group will have 4 cookies. Therefore, 12 divided by 3 equals 4. We write it as 12 ÷ 3 = 4."

  "Division is very useful in our daily lives. For example, if you want to share something equally, like a pizza or a pack of crayons, you are using division."

  "Can anyone give me another example of when we might use division in real life?"

Work Flow

Step 1: Direct Instruction (10 minutes)

  • "Let’s look at another example: If I have 15 apples and I want to share them equally with 5 friends, how many apples will each friend get?"
  • (Write on the board: 15 ÷ 5 = ?)
  • "We divide 15 apples by 5 friends. Each friend will get 3 apples. So, 15 divided by 5 equals 3."
  • "Now let's try a few more examples together."
  • "What if we have 20 candies and we want to share them with 4 friends? How many candies will each friend get? Yes, 20 divided by 4 equals 5."
  • (Write on the board: 20 ÷ 4 = 5)
  • "Let's do another one: If we have 18 marbles and we divide them equally among 6 friends, how many marbles does each friend get? Correct, 18 divided by 6 equals 3."
  • (Write on the board: 18 ÷ 6 = 3)
  • "Great job! Now let's try some harder ones. What is 36 divided by 6? Yes, it is 6."
  • (Write on the board: 36 ÷ 6 = 6)
  • "One more: 48 divided by 8? Yes, it's 6."
  • (Write on the board: 48 ÷ 8 = 6)

Step 2: Interactive Discussion (15 minutes)

  • "Can anyone think of a situation where you would need to divide something?"
  • "Great! When you have something like a pizza and you want to share it with your family, you use division."
  • "Let's think about other times you might need to divide things. How about in sports? If we have 12 players and we want to make 4 teams, how many players will be on each team?"
  • (Write on the board: 12 ÷ 4 = 3)
  • "Yes, there will be 3 players on each team. Can anyone think of another example?"
  • "How about sharing toys? If we have 30 toy cars and we want to share them with 5 friends, how many cars does each friend get?"
  • (Write on the board: 30 ÷ 5 = 6)
  • "Exactly, each friend gets 6 cars."
  • "Now let's discuss a real-life scenario: If a family has 24 cookies and they want to share them equally among 6 people, how many cookies will each person get?"
  • (Write on the board: 24 ÷ 6 = 4)
  • "Yes, each person gets 4 cookies."
  • "What about at school? If we have 36 pencils and we need to divide them equally among 9 students, how many pencils does each student get?"
  • (Write on the board: 36 ÷ 9 = 4)
  • "Right, each student gets 4 pencils."

Step 3: Hands-on Activity (15 minutes)

  • "I’m giving each group a set of counters. Use these counters to solve the division problems on your worksheet. (Annex 1)"
  • "For example, if you have 10 counters and you want to divide them into 2 groups, how many counters will be in each group?"

Step 4: Group Work (15 minutes):

  • "Now, let's work on some word problems in pairs. Remember to think about how you can use division to find the answer."
  • (Distribute Annex 2: Word problems worksheet)
  • "Read the problem carefully, decide what you need to divide, and find the answer together."

Step 5: Cut-and-Paste Activity (20 minutes):

  • "Next, we have a fun cut-and-paste activity to help us understand division better."
  • (Distribute Annex 3: Cut-and-Paste activity)
  • "Cut out the pictures of different items and glue them into equal groups to match the given division problems."

Step 6: Closure (5 minutes):

  • "Let's review what we've learned today. Who can tell me what division means?"
  • "That's right! Division is splitting a number into equal parts."
  • "Now, who can give me an example of a division problem we solved today?"
  • "Excellent! Remember, division is all about sharing equally. Whether you're dividing cookies among friends or pencils among classmates, you are using division."
  • "Take a moment to think about how you might use division at home or in other activities. Division helps us make sure everyone gets an equal share."
  • "Great job today, everyone! Keep practicing your division skills and soon you'll be a division expert. See you next time!"
Reflection

Guided discussion using the prompts:

  • Reflect on the lesson by discussing with your partner: What was easy about division? What was challenging?
  • Think about a case when you used division outside of school. How did it help you?
  • Can you come up with your own division problem and solve it? Share it with the class.

Warm-up Activity (5 minutes):

  1. Teacher: "Good morning, class! Today, we're going to learn about some important terms in division: dividend, quotient, divisor, and remainder. Let's start with a quick review. Can anyone tell me what division is?"
  2. Allow students to respond.
  3. Teacher: "Great! Division is breaking a number into equal parts. Let's use some blocks to practice dividing. If we have 12 blocks and we want to divide them into groups of 3, how many groups do we have?"
  4. Use blocks to demonstrate dividing 12 into groups of 3, and count the groups together.

Introduction of Key Terms (10 minutes):

  1. Teacher: "Now, let's learn some new words. Look at this chart (Annex 2)."
  2. Show Annex 2 to the class, with definitions and examples.
  3. Teacher: "In division, the number we start with is called the dividend. Let's say we have 12 blocks again. The 12 is our dividend."
  4. Write "12 (dividend)" on the board.
  5. Teacher: "The number we divide by is called the divisor. If we divide by 3, the 3 is our divisor."
  6. Write "3 (divisor)" on the board.

The students stand in a circle. The teacher starts, pretending he/she is holding a ball on the hands and passing it to the student on his/her right; this one do the same, until the ball comes back to the teacher. The ball needs to be passed in a gentle way, as it is very precious. At the second round, the teacher passes the ball to students in another side of the circle, making a gesture and a noise. The students will do the same until everyone will have touched the ball at least once.  The ball can be passed in any way (in form of kick, kiss…), pretending it becomes bigger or smaller depending on the will of the students.

Introduction

Geometric shapes are all around us. We already know that the circumference of a geometric figure, e.g. а square, а rectangle or а triangle, indicates the total length of its outlines. And the area of a geometric shape shows how big the space enclosed by the outlines of the figure is. But what do we need to know that for?

Imagine that your parents agreed to paint one of the walls in your room a new colour and are wondering whether they would buy 1 or 2 cans of paint. On the packaging of the selected paint, it is written what surface can be painted with it. But how can we find the area on the wall? In this lesson you will learn how to find the area of a rectangle and you will be able to help your parents buy the correct number of cans of the paint to paint the wall in your room.

Work Flow
  1. Rectangles – revision (10 min.)

1.1. Show different objects in the room that have the shape of a rectangle - the door, the windows, the blackboard, the computer/laptop monitor, etc. Ask them to add more examples from everyday life. You can use the video https://www.youtube.com/watch?v=U_D56_HQBnQ

1.2. Show a drawing of a rectangle. You can use a rectangle pattern that you have previously drawn and cut out. The rectangle is a geometric shape students already know. Revise its elements and features with the students. Ask questions and comment on the answers. Remember the students that a rectangle has 4 sides and 4 vertices; all its angles are right angles; the lengths of the opposite sides are equal; one pair of sides is longer than the other pair. For each of the features described, do the corresponding demonstration on the model you are using.

1.3. Another option is to use the presentation Elements of a rectangle to do the revision.

  1. Students receive Handout 2 where they can see a rectangle with sides 6 cm and 3 cm. Have them use 2 different colors – one colour for the two longer sides and another one for the two shorter sides. Task:

Task 1: Repeat the dashed lines along the outlines of the rectangle starting from the lower left corner. After drawing each side of the rectangle, put down its length in the assigned order.

After completing the task, the teacher sums up what students have done - by tracing the sides of the rectangle, they actually "have gone around" it – this is the perimeter of the rectangle.  

Task 2: Calculate the perimeter of the rectangle using the formula.

Alternatives of drawing the sides of the rectangle:

  • Make use of a geoboard and stretch bands, so that the students with learning difficulties can outline the shapes and see how many units the different sides of the shapes are;
  • Make use of an online geoboard tool. (5 min.)

Ask the students to colour the inside of the outlined part of the sheet (any colour), and explain that the lesson is about this coloured part (we call it  area of a rectangle) and what to do to find out how big it is.

  1. Area of a rectangle - introduction (10 min.)

3.1. Distribute a set with the shapes from Handout 3 to the tables so that students work in couples. Provide some time to see the shapes and set the task to think about the common characteristics of all shapes and differences between them (Common characteristics: all shapes are rectangles that are made up of squares of the same size. Differences: the rectangles comprise different number of squares.)

3.2. Explain that the sides of the small squares that make up the rectangles are 1 cm, and introduce the concept of a square centimeter. Introduce the way we write 1 square centimeter in mathematics - 1 sq. cm or cm2.

3.3. Discuss the green (the first) shape. If we count the number of squares it comprises of, we will know its area. The area of a rectangle is measured in square centimetres, and the number of squares indicates how many square centimeters the area is.

3.4. Task: Count the number of squares and determine the area of the green shape, the yellow shape and the brown shape.

  1. Area of a rectangle – practical work. (20 min.)

4.1. Distribute Handout 4 to each student, specifying that the sides of the small squares are 1 cm. Have the students count how many squares cover each rectangle and record the results.

Alternatively, you can suggest another smart way of finding the number of squares each rectangle is made of – this can be done by counting the rows and columns of squares into which the rectangle is divided, and the total number can be reached by multiplication.

4.2. You can use suitable animations to illustrate how to find the number of squares that cover a rectangle, for example https://www.google.com/search?client=firefox-b-d&q=animation of area of rectangle#fpsstate=ive&vld=cid:96e89487,vid:41ADSvcoRKo . 

4.3. Distribute Handout 5 for individual work.

Task: Determine the areas of the rectangles and put a ball of plasticine or a paper clip on the one with the biggest area.

4.4. Distribute Handout 6 and the pre-cut squares with a side of 1 cm to the tables for pair work.

Task 1: Cover the rectangles with the small pre-cut squares, lining them up tightly next to each other.

Task 2: Find the area of each rectangle.

  • This can be done by counting the small squares, or by multiplying - the number of rows by the number of columns with squares. Let each pair work in their preferred way.

Alternatively, students could divide the rectangles in the square grids into 1 cm squares.

4.5. Final wrap-up: The area of a rectangle can be calculated by multiplying the lengths of two adjacent sides.

Students receive Handout 7 with the task of identifying the area of each shape. The dimensions of the first two rectangles are provided, and for the others it is necessary to measure the lengths of the sides first and then, calculate the area.

  1. Present some examples from everyday life that illustrate what we need to find the area of a rectangle for. You can use the presentation or print the pictures in the slides and distribute them to the students. For each photo, discuss what the area of the rectangle needs to be calculated for, for example for tiling a bathroom floor, painting a wall, etc. Ask students to think of their own examples of situations in which it is necessary to find the area of a rectangle. Summarize the activities and the new knowledge and skills the students have acquired in the lesson. (5 min.)
  2. Finish the lesson with e-games: Students play the games on their mobile devices or the teacher opens a game on the screen and volunteer students take turns to come to the front and play. (10 min)

Game 1: https://wordwall.net/resource/59362006

Game 2: https://wordwall.net/resource/59356082

Reflection

Discuss the following questions in the plenary:

  • Do you think you learned something you can make use in everyday life today? What?
  • Which activities did you like more – when you worked individually or when you worked in pairs? Students divide in two groups according to their answers and discuss in the groups what they liked specifically. After that, a reporter from each group sums up the answers.

Students get into a circle with sheets of paper and coloured pencils in the centre of the room and all students are invited to express, through colour, an emotion or feeling, by using different colours and painting them on the sheet of paper. When they have finished colouring, all the students show the sheet of paper and explain what that colour represents at that moment. If it is something negative, the classmates must voluntarily offer him/her other colours that transmits a positive emotion, that represents something positive. The aim of the game is that everyone feels free to share a feeling and receive peer support if needed.

Relaxing Exercises senpower     24 - The Pot of Calmeness

We call "the pot of calmness" to a jar in which we put water, liquid silicone to give density to the content and glitter of different colours.

The construction of the jars is done in advance by the students and they can remain in the classroom to be used at other times when the call for relaxation and calmness is necessary. 

Each student gets his/her jar, shakes it and observes the movement.  Afterwards, the group talks about what is observed:  that the glitter represents the students’ emotions that they shake and stir until they are calmed down. This activity is ideal for fostering reflection.

The simple act of watching the glitter moving slowly will help the students to relax.

· Analyse and interpret statistical information represented in absolute and relative frequency tables and bar graphs;

· Communicate reasoning based on the data collected in the tables and processed in the graphs.

Preparation

MATERIAL:

· Glass jars with lids · Sticky paper or insulating tape · glitter;

· Water;

· Liquid silicone

· Sheets of A4 and A5 paper

· Water-resistant tape

· Coloured pencils · Scissors;

· Printouts on sheets of A3 and A4 paper;

· White reusable adhesive putty;

· Individual student computers.

Lesson pre-preparation

Ask each student to bring a glass jar with a lid to school. Each pupil makes their own "pot of calmness" by putting water, liquid silicone to make the contents dense and coloured glitter into the jar. Then close the jar and wrap waterproof tape around the lid to make a better seal. Preparing the lesson There should be a table with all the necessary materials for the execution of the plan, including the pots of calmness.

Introduction

In our daily lives, we are constantly in contact with statistics presented in different ways. It is therefore an essential subject for everyone, as it is necessary to know how to analyse and interpret this information. Using situations which are close to the students and which encourage and support meaningful mathematical learning, we will record and then organise the data collected, exploring the collective construction of absolute frequency tables and graphs. Students will ask and answer questions related to data collection and finally analyse and interpret the results in an organised manner.

Teaching and learning methods

The teaching learning is process based on concrete questions and proximity situations to students. Learning by doing through the effective manipulation of material, making awareness o easier of what is being learned. Cooperative and collaborative learning - work developed in cooperation and collaboration in groups and pairs. New technologies as a way of learning/consolidating contents.

Interdisciplinary connections

Portuguese Language – Listening and selecting relevant information, using different recording of data register techniques; Expressing opinions and sharing ideas audibly, with good articulation, appropriate intonation and rhythm; Ensure eye contact with the audience (body posture, facial expression, and gaze).

Natural Science – Asking questions, making hypotheses, making inferences, checking and communicate results, recognising how knowledge is constructed.

Artistic Education – Constructing the "pots of calmness" and drawing emotions.

Citizenship and Development - Human Rights - Developing attitudes and behaviours of dialogue and respect, underpinning ways of being in society, contributing to the formation of responsible and supportive people, fostering attitudes of personal and social responsibility.

Resource teacher or other specialists activities

All steps of the topic development must be understood for SEN students with cognitive abilities. The lesson does not include long written explanations. The role of the support or special education teacher is to help students in the target group if they are unable to complete any of the tasks or steps of the lesson, or feel confused in understanding something that may be required.

New vocabulary

Statistical information; absolute frequency; relative frequency; bar graphs.

Work Flow

1st STEP

Listening is an essential activity in the educational context and strengthens the development of the empathic side of teachers and students. After an early approach to the theme of empathy with the involvement of learners. At this moment students are proposed to work acts of empathy in the class, to be marked daily on a double entry board with the days of the week and the acts of empathy, (Appendix 1) which are:

  • Asking for permission;
  • Praising someone;
  • Sharing something;  
  • Helping a colleague with a school task;
  • Offering help to someone.

Each act of empathy will correspond to a colour that makes it easier to differentiate them. During the week, at the end of the day, each student goes to the blackboard and there marks the act of sympathy which, in his or her opinion, he or she practised that day. The board should be fixed with white reusable adhesive mass, on a wall of the classroom at the height of the students.

2nd STEP

At the end of the week, the class as a whole, will count the data previously recorded on the table and registered the numbers on a A3 size sheet, (Appendix 2), with dashes (|). The table should be placed on the wall next to the blackboard.

3rd STEP

It is necessary to present the data recorded in the counting table in an organised way. Students in pairs will construct a frequency table: absolute frequency, which is the digit/s that corresponds to each count of the traces (I), and relative frequency, which implies activating prior knowledge and transforming the same digit into a fraction. The fraction will always depend on the number of students present in class on each day, i.e. if there were 20 students on one day and five of these, students performed a specific act of empathy, then the transformation into a fraction is

After completing the table, collectively the class answers the following questions:

  • What was the most recorded act of empathy?
  • What was the least recorded act of empathy?
  • Was there an act of empathy that was never recorded?

(Appendix 3)

4th STEP

After completing the table, in groups of 4/5 students, the acts of empathy will be recorded in a bar graph, on pre-prepared A4 paper (Appendix 4), with the aim of visually representing data and information which would allow a quicker and clearer understanding of the acts of empathy which were more or less presented. Each group works on the acts practiced on each day of the week. After the groups have constructed the various graphs, the graphs are placed on a wall or whiteboard (with white flexible and reusable adhesive), one next to the other.

Observing visually the values on each day, one group at a time answers the following questions:

  • Which acts of empathy were most practised on each day of the week?
  • Which day or days of the week were the most empathetic for the students?
  • Which day or days of the week were the least empathetic for the students?               

5th STEP

Assessment of the acquired learning through Forms, available on Teams, with each student using their own computer with internet access: ·

  • Do you think it is important to learn to make graphs? Yes/No
  • An absolute frequency table is used to:
    - Select the correct answer/s:
    - Presenting data in an organised way;
    - To learn how to count; ·
  • What mathematical language was used in this activity? Tick the correct answers:
    - Divisor;
    - statistical information;
    - Vertex; 
    - absolute frequency;
    - symmetry, relative frequency;
    - bar graphs.

  • Relaxation activity
  • The Pot of Calmness;
  • Group dynamics - Game - Empathy game;

Developed by NART
Grade 4
Duration 45
Energizers senpower     30 - Find the figure

Option 1

Divide the class into several groups.

Each group gets 1 set of the shapes and explanatory texts (Annex 1) - cut out separately each statement that describes the shape.

The task of each group is to match the statements with the images of the shapes.

When the groups are ready, check if the task was competed correctly.

This exercise serves both to energize the students at the beginning of the lesson and as a transition to the topic of the lesson.

Working time – 8 min.

Option 2

Rearrange the tables (or desks) so that students can move freely around the room.

Place the images from Annex 1 in the corners of the classroom.

Allow each child to pick up a card with a description of a geometric figure. The task is to get as quickly as possible to the place with the geometric figure that corresponds to the description of the card.

This exercise serves both to energize the students at the beginning of the lesson and as a transition to the topic of the lesson.

Working time – 3 min.

Relaxing Exercises senpower     28 - The shape I found first

Option 1

Ask the students to take their seats.

If you used option 1 to move around, ask each team which geometric shape they recognized first and last.

If you used option 2, ask the children if they have figured out what the hidden geometric figures are. Let them name all the shapes at least 2 times.

Option 2

Guided fantasy

Students are asked to close their eyes (if comfortable) and, with the guidance of
the facilitator, slowly imagine a scene of a past or future event. More and
more details are added to describe the event with all senses and thoughts. Suggested short script:

- Start breathing slowly and deeply...

- Imagine that you are in a place where you feel calm and relaxed...

- Create the details in your mind. What can you see?

- Do any of the objects resemble the shapes we talked about today? Is there a predominant shape?

- What are the sounds, smells and colors of this special place? Do you associate any of the sounds with a particular shape? Or any color?

- Open your eyes.

Time – 3 min.

Objectives

Recognizing the geometric shapes cube, rectangular parallelepiped, sphere, cylinder, cone, pyramid.

Developing self-confidence.

Building a connection between geometric shapes and everyday objects.

Stimulating student’s imagination to discover patterns and similarities.

Preparation

1. Make 1 color copy of each of the geometric figures from Annex 1 in A4 size (fig 1 – 4).

Print out the necessary number of copies of the texts that describe the shapes so that each student gets one description, for example: if there are 20 students in the classroom, you will need 5 copies of Annex 1.

Cut out the descriptions of the geometric shapes separately.

2. Get a box of big and strong toothpicks and several packages of plasticine.

3. Organize the pictures from Annex 2, Annex 3 and Annex 4 as separate slides in one presentation or simply as separate pictures in a folder on your laptop.

4. Prepare sets of toothpicks and plasticine – the number of sets should correspond to the number of tables in the room, keeping in mind that in each set there should be enough materials for each student to work with. Each set should also include templates with the geometric figures square, triangle and rectangle. Or you can provide a set for each student, or one per couple.

5. Print Annex 5 on slightly stiffer paper.

Materials

  • Plasticine
  • Toothpicks

Equipment

Laptop and projector

Tablets with applications for creating geometric shapes according to set parameters (optional)

Introduction

Geometric shapes are all around us. They are part of our daily life. We are so used to them that we no longer even see them as geometric shapes, but only as objects. In the following lessons, we will learn to recognize them. We will also see how artists use geometric shapes to create art.

Teaching and learning methods

Learning in small steps

Breaking instructions down into smaller parts

Using patterns

Using technology and visualization

Providing real-life examples

Using manipulatives

Interdisciplinary connections

Arts – Piet Mondrian

History and Geography - the pyramids in Egypt, Mexico, Paris, Louvre Museum

Technology

Resource teacher or other specialists activities

Almost all the steps of the lesson are comprehensible to most special needs students who have well-preserved cognitive abilities. The lesson does not comprise long written explanations, and the long instructions, which are difficult for the target group’s students (TGSt), are not many.

The role of the special needs teacher or the assistant teacher is to help TGSt in case they are not able to cope with some of the tasks or steps.

Modeling with plasticine and creating constructions are activities that most students with learning difficulties enjoy a lot.

An alternative to measuring geometric shapes is to use a geoboard and rubber bands so that students with learning difficulties can trace the shapes and check how many measuring units the different sides of the shapes comprise.

When practicing the names of the shapes, the special needs teacher can sit next to the student(s) with learning difficulties and clearly repeat the names (but do not force the children to pronounce the word ‘’parallelepiped”).

New vocabulary

cube, rectangular, parallelepiped, sphere, cylinder, cone, pyramid

Work Flow

1. Introduction to the lesson.

Explain that today they will learn to recognize several new very important geometric shapes that are present in our daily lives. We are so used to them that we no longer even see them as geometric figures, but only as objects.

We will also see how artists use geometric shapes to create art.

Working time – 2 min.

2. Make a connection between the geometric shapes students already know (triangle, circle, square and rectangle) and the new geometric shapes (pyramid, sphere, cube and rectangular parallelepiped).

Option 1: Use consistently the pictures from Annex 2 - geometric figures.

Option 2: Make use of templates in Annex 5 for constructing the geometric shapes (templates are to be printed on cardboard or thick paper)

Option 3: If possible, provide big 3D models of the new shapes and place them on the table so that the children can see them during the lesson.

You can also search the internet for short videos on how to draw the new shapes and play them to the class.

Introduce the name of each shape; laugh at the pronunciation of parallelepiped (probably difficult for most children).

Pay special attention to the cylinder and cone shapes. Depending on the position we are looking at them, we will see them differently.

Here are some examples:

You can play the video https://www.youtube.com/watch?v=uohP-OwLS4k&ab_channel=ReignEDU

3. Hands-on learning.

Distribute the sets of plasticine and toothpicks and the templates from Annex 2 with the geometric figures circle, square, triangle and rectangle. Instruct the students to make 2 geometric shapes of their choice: e.g. a triangle and a pyramid, or a square and a cube, or a rectangle and a rectangular parallelepiped.

Provided that more time can be devoted to the lesson, each student can make all the figures.

Steps:

  • Distribute the templates with the geometric shapes.
  • Tell the students that they must first make the 2D geometric shapes using the toothpicks and small balls of plasticine to connect the toothpicks. Explain that everyone will make spheres (small balls), because the toothpick connecting parts are exactly plasticine balls.
  • Firstly, students are expected to make the 2D shapes similar to ones below:

  • The second part of the task will result in making the 3D shapes which are expected to look like the ones below:

  • Ask students to measure the sides of the geometric shapes from Annex 2 and put down the results on the side of each shape.
  • Ask students to write beside each 2D shape in Annex 2 (the left column) how many sides the shape has and how many vertices.
  • Task No.3 is to count how many sides, edges and vertices the new geometric shapes (the right column) have - the pyramid, the cube and the rectangular parallelepiped. Compare the data and discuss them.
  • Ask the students to identify which of the geometric shapes that you placed on the table at the beginning of the lesson are not made of plasticine and toothpicks (the cylinder and the cone). Explain that the cone has only 1 vertex and the cylinder and sphere are the figures that have no vertices.
  • Revise the names of all the shapes once again and tell the students that they will learn more about each shape in the following lessons.

Working time – 15 min.

4. Geometric shapes in art and life.

  • Art: Show the first two slides from Annex 3: Geometry and Art. Explain that the images are paintings by Pieter Cornelis Mondriaan (Piet Mondrian) - a Dutch artist who created paintings using only different geometric shapes and the primary colors (ask students to name the primary colors – red, blue and yellow). Inspired by his paintings, one of the greatest designers of women's clothing, Yves Saint Laurent, designed a whole collection of outfits, which he named after the artist.

Tell the students that they will step in the shoes of artists and designers themselves in the the Arts classes when they will use stencils to make their artwork. Show the rest of the images as an example and inspiration.

You can possibly make use of the cardboard and plastic stencils and the paints to design other pieces of art with the geometric shapes in Technology and Entrepreneurship or Fine Art classes.

  • Geometry shapes in life: Show different objects that are used in everyday life by challenging students to guess what the geometric shape of each object is. At all times, the geometric shapes from the beginning of the lesson are placed on the teacher's desk so that everybody can see them.

Use the pictures from Annex 4 – Geometry in daily life. Make a slideshow. At the discretion of the teacher and according to the specifics of the students, three options can be used:

  • The first option is more systematic and makes it possible to consolidate the names of the geometric shapes with their manifestations in life. Show the geometric shapes on the screen one after the other. For each image the students have to say the name of the shape in response to the question "Which geometric shape do you see?".
  • Option 2: Shuffle the pictures and the students have to guess the name  geometric shape.
  • The third option is a combination of the previous ones. Firstlye, show 3 or 4 images of a the specific shapes on the screen. The rest of the images need to be shuffled and the students have to name geometric shape they see.

Working time – 10 min.

Reflection

Final wrap-up: Finish the lesson by having students look around the classroom. Ask them which geometric shape it looks like. Then ask them to look at other classroom objects: textbooks, pencil cases, or other items in their bags. Let everyone name their discoveries.

An additional activity is to provide students with tablets and allocate time to create their own geometric shapes by drawing them with appropriate applications (in case the school has the appropriate devices and software). You can also ask the class, as a homework assignment, to find out different objects resembling the new geometric shapes at home.

Working time – 10 min.

2. Provide a good amount of used coffee capsules, properly cleaned, organized by colors. The idea is that each student can choose the color of their preference for this activity.

3. Students should be organized into groups of 4 participants in order to make simulations in the first part of the task.

4. Print a copy of the registration board (Annex 2) for each group.

Introduction

Mathematical reasoning is a fundamental aspect of mathematical knowledge and its development should be promoted from the earliest years of schooling and specifically with students with special learning needs. One of the central aspects of this work is the recognition of regularities and the mobilization of inductive reasoning to formulate generalizations in the form of conjectures. This process will open opportunities for the construction of arguments with progressive levels of abstraction. Solving the activity presented in this lesson plan, students will have the opportunity to follow an exploratory learning path with great meaning and reach, starting from a problem.

Teaching and learning methods

Exploratory learning from real-life situations.

Interdisciplinary connections

Language – oral and written communication.

Resource teacher or other specialists activities

Almost all the steps of the lesson are comprehensible to the majority of students with special needs who have well-preserved cognitive abilities. The lesson does not comprise long written explanations, and long instructions, which are difficult for the target group students.

The role of the special needs teacher or the assistant teacher is to help target group students in case they are not able to cope with some of the tasks or instructions provided.

New vocabulary

Conjecture

Work Flow

Phase 1: Explore and understand the proposed problem

After organizing students into groups of 4, the following problem is presented:

On the last day of classes, a group of primary school students from grade 2A decided to give each other souvenir gifts. How many gifts are given altogether?

The presentation of the problem could be done using the image (Annex 3) projected on the screen from a laptop computer.

This first phase is about understanding of the problem. Students must figure out the meaning of "give each other souvenir gifts". It should be made clear that, under these conditions, each person gives a gift and receives a gift from each of the other members of the group. The formulation of the problem is deliberately vague so that student do not know the number of students in grade 2A that constitute the group. This is intended to compel students to explore the context, considering groups formed by a reduced number of peers, allowing the teacher to give the trivial example of 2 people: Each one must bring 1 gift (to offer to the other). Altogether, there are a total of 2 gifts.

5 min

Phase 2: Explore and identify regularities

At this stage, students should choose a character card (Annex1) and a colour, according to their preference Figure 1. Characters cards and coffee capsules with different colours.

These resources are going to be used by the students to explore the presented situation. The character card represents an element of the group. Each coffee capsule of the chosen colour represents a gift to be distributed to each of the remaining elements of the group.

Students have already researched the case when the group of 2ª students comprises 2 students. Now, the teacher can ask "And what happens if the group is made up of three (Figure 2) or four students (Figure 3)?" Students explore each case using the resources mentioned above.

.Figure 2. Representation of the problem solution for a group of three students

Figure 3. Representation of the problem solution for a group of four students.

The results obtained are recorded on the registration board (Annex 2).

The exploration can be extended to groups with a greater number of elements. For this purpose, the previous groups can be combined two by two.

At this stage, the structure underlying the question asked should be more or less evident, and its rectangular representation more clear, such as in the resolution for a group of five students (Figure 4).

Figure 4. Representation of the problem solution for a group of five students.

The gifts altogether correspond to: the product of the number of elements in the group by the number of gifts that each element should offer (and obviously receive), as seen in the previous example.                                                                                                                         20 min

Phase 3: Conjecture and verification

As a result of the observation of the analysed cases and the observed regularity, it will be possible to conjecture the number of gifts each student should bring to the party and the total number of gifts, such as presented on Table 1.

Table 1. Conjectures of the number of gifts each person should bring to the party and the total number of gifts.

The total number of souvenir gifts in a group of students where everyone gives each other a gift equals the number of elements of the group times the number of elements of the group less 1.

The formulation of the conjecture can be done only using words or algebraic language, according to the level of proficiency of the students. Another way of generalizing the result found is to solve the proposed problem applied to a larger number of elements in the group, without reference to the simulation and representation provided by the materials previously used. An answer to the following question could be proposed:

On the last day of classes, all students from our class decided to give each other souvenir gifts. How many gifts are given altogether?

For example, in a class of 20, there would be a total of 20×19=380 gifts.

15 min

Reflection

Guided discussion:               

  •   What is the solution of the gift problem presented:

Proposed solution: The total amount of gifts is the product of the number of elements in the group by the number of gifts that each element should offer.

  • What is the algebraic representation of the problem solution?

Total number of gifts: n × (n – 1)

Objectives

Students will:

  • Learn to determine the value of a variable in a simple one-variable equation of addition and subtraction.
  •  Improve their reasoning skills.
  • Imrpove their teamwork skills.
Preparation

Materials:

  • Whiteboard or blackboard
  • Markers or chalk
  • Manipulatives (different colours of counters or blocks)
  • Crayons for Annex 3

Preparation: Print Worksheets for practice - Annex 1, Annex 2.

Introduction
  • Review the concept of numbers by counting count the desks in the classroom (a whole class activity).
  • Ask individual students to count backwards from 20 .
  •  Review of basic arithmetic skills: Ask students to count by adding 2 (start from 2. i.e. 2, 4, 6, 8, 10, etc.)’; start from 3 and count by adding 3, i.e. 3, 6, 9, 12, 15, etc.) After the answers celebrate students' success.

Review basic addition/subtraction operations. Ask the students to answer these basic addition/subtractions problems: 5 + 1= ??; 7 + 9= ??; 8-3 = ??; 9-1 = ??

Teaching and learning methods

1.     Direct Instruction: The teacher presents new concepts and explains how to solve equations step-by-step. Direct instruction is used to provide clear explanations, demonstrate problem-solving strategies, and introduce new concepts to the students.

2.     Real-Life Examples: The use of real-life examples helps students relate the concept of variables and equations to situations they encounter in their daily lives. It makes the learning experience more meaningful and relevant.

3.     Visual Aids: Visual aids manipulatives (e.g., counters or blocks) are used to make abstract concepts more concrete and understandable for students.

4.     Group Work: Students are encouraged to work in pairs or small groups to solve practice problems and word problems. Group work fosters collaboration, communication, and peer learning. It also allows students to discuss their strategies and learn from one another.

5.     Practice Worksheets: The use of practice worksheets allows students to apply the concepts they've learned independently. Worksheets provide opportunities for students to practice solving equations and reinforce their understanding.

6.     Checking Answers: Emphasizing the importance of checking answers helps students develop a habit of verifying their work for accuracy. It also promotes a deeper understanding of the concepts and helps students identify potential errors.

7.     Positive Reinforcement: The teacher celebrates students' successes and progress throughout the lessons, boosting their confidence and motivation to continue learning.

Some students may take more time to grasp the concept of variables and equations. Be patient, provide additional support, and adapt your teaching approach if necessary.

New vocabulary

Variable, addition, subtraction, equation, unknown, balance.

Work Flow
  1. Introduction to Equations and Variables (5 min.)

Start by asking students if they know what an equation is .After the answers explain that an equation is a mathematical statement that shows that two expressions are equal.

Introduce the concept of variables as placeholders for unknown values. Use simple real-life examples . Tell the students: Imagine we want to play "Tug of War" game. We have Team A with 10 students but Team B has only 5 students. The number os students in the teams is not equal and it wouldn’t be fair to play like that. In order to make the participants in the two teams equal we need 5 more students to join team B. This case we can record  with an equation as follows:  5 + ⃣  = 10. The missing numver in the square is a variable. In the equation, the variable is represented by '  ⃣ .'

  1. Finding a variable in addition and subtraction equations by using manipulatives.

  Manipulatives are physical objects that students can touch, move, and interact with, which helps them visualize the problem and gain a better understanding of the mathematical concepts involved. Blocks: Provide students with counters or blocks of different colors. In the addition and subtraction equations, have students physically move the blocks to represent the numbers in the equation.

  • Addition equation 3 +  ⃣  = 8.

Place 3 blocks on the left side of the table, and 8 blocks on the right side. Are they equal? (Answer: NO). Then, add more blocks to the left side one by one until both sides are equal and check at every step: put a blank sheet of paper on the left side and place 1 extra block on it; count all the blocks on the left side: we have 4 on the left and 8 on the right side, Are they equal?  NO. Put one more block on the paper and count; we have 5 blocks on the left side all together, and 8 on the right side. Are they equal?  NO. Continue the process until students have placed 5 blocks on the paper sheet on the left side and have theme count the blocks. In this case we have 8 blocks on the left side and 8 blocks on the right side – they are equal. How many blocks are there on the paper sheet? – 5 blocks. This is the unknown number (the variable) in the initial equation  3 +   ⃣  = 8

one more visually showing how to solve the equation. After example make three groups and give each group an equation to solve with blocks. (Write the each group’s equation on board)

  • For subtraction equation ask students to use two different colours of manipulatives; for example place 5 blue counters on one side and put 2 red counters to the other side to present the equation: 5 -   ⃣  = 2. Ask how many blue counters do I have to take away from the left side so that we have 2 blue counters (this is the same number as the number of counter we have on the right side). Students take away the counters from the left side one by one and put them aside until they have only 2 left. They count the number of counters they have taken away and put aside (3), and this is the value of the unknown number (the variable) in the  equation 5 -   ⃣  = 2 ; so   ⃣  = 3
  1. Finding a variable in addition and subtraction equations (5 min.)

   Tell students that addition and subtraction are inverse operations. If you add 5 to a number and then subtract 5 from the result, you will get back to the original number.

  • Example: 7 + 5 = 12, and 12 - 5 = 7. Show this by using manipulatives. Put 7 blocks together and then add 5 more blocks. After adding, count the blocks. Ask the students what the result is - 12. Then, take away 5 blocks from the 12 blocks and ask how many blocks are left (7).

Show students step-by-step methods to solve equations using inverse operations - write all operation steps on the board.

  • Step-by-Step Method for solving Addition Equations - example equation: 3 + ⃣  = 8

Step 1: Ask students to Identify the variable (  ⃣ .).

Step 2: Use inverse operation to isolate the variable. To isolate the variable '  ⃣ ,' use the inverse operation of addition, which is subtraction. Subtract the number which stands on the left side of the equation where the variable is (3) from both sides of the equation: 3 +  ⃣  - 3 = 8 - 3

Step 3: Simplify both sides. The left side simplifies to '  ⃣ ,' and the right side simplifies to '5':   ⃣  = 5

Step 4: Check your answer. Substitute the value of '  ⃣ ' back into the original equation to make sure the answer is correct: 3 + 5 = 8; 8 = 8 (True)

  • Step-by-Step Method for solving Subtraction Equations. Break down the subtraction process into simple steps. Similarly, show students how to identify the variable, isolate it on one side of the equation, and perform the necessary operations to find its value. Example "Imagine you have 10 pencils and give away some of them to your friend. After you do that, you have 6 pencils left. How many pencils did you give to your friend?" After getting the answer write this equation on board:

10  -  ⃣   = 6

Step 1: Add the unknown number (the variable   ⃣   to both sides.

10 -  ⃣   +   ⃣   = 6  +  ⃣

Step 2: Simplify the equation

-  ⃣   +   ⃣   = 0, so we get

10 = 6  +  ⃣

Step 3: Isolate only the variable on the right side by subtractibg 6 from bothe sides:

10 - 6 = 6  +  ⃣   - 6

6-6 =0; and 10-6 =4, so we get

4 =   ⃣

Step 4: Check your answer. Substitute the value of '  ⃣ ' back into the original equation to make sure the answer is correct:

10 – 4 = 6; 6 = 6 – the answer is correct.

  1. Distribute Annex 3 and crayons to the students. Task: Colour the correct number of apples so that he equations are correct. Check the answers.
  2.  Students work individually to solve the problems from Annex 1.  Check the answers as a whole class activity.

Reflection

  • As a homework assignment Annex 2 can be given to students
  • Review the lesson's learning objectives and note students' progress.
  • Identify any specific difficulties or challenges faced by individual students
Notes

Remember to emphasize the importance of checking their answers. Encourage students to double-check their work and ensure that their final answer makes sense in the context of the problem.

Encourage active participation from all students during class discussions and group activities to ensure everyone is engaged in the learning process.

Duration 1h25
Energizers senpower     47 - Pig Game

“Pig game” is a simple dice game which in its basic form is playable with just a single dice. You win by being the first player to achieve a certain number of points.

To play you'll need 2 to 10 players, one 6-sided dice, and a pencil and some paper for keeping score.

The teacher organizes the class into four or five groups, each acting as a team. Each group rolls a dice to determine the order of play, with the highest number of points going first, followed by the next highest, and so on. If possible, use a large dice made from soft material so the activity can take place with students standing and moving.

The first team rolls the dice and scores the number of points shown, provided they do not roll a 1. If the team rolls a 1, their turn ends, and they lose all the points accumulated during that turn, passing the die to the next team. Team members must decide collectively whether to continue rolling and risk rolling a 1 (and losing their points) or end their turn and keep the points earned.

Scores can be recorded on the whiteboard or blackboard. Play continues from team to team until a winner is determined. The first team to accumulate 50 or more points wins the game.

Relaxing Exercises senpower     42 - Sharing strategies

Students sit in a semicircle, facing the teacher, and discuss what is the best strategy to win the “Pig game”. Children can express their opinion, make experiments or demonstrations.

Objectives
  • Express greater or lower degree of uncertainty relative to occurring events resulting from random experiments through terms such as ‘likely’ or ‘probable’.

  • Compare the results of a random experience based on its likelihood.

  • Produce, collect and organize data in order to understand simple probabilistic models.

Preparation

Materials:

  • Empty matchboxes

  • Solid color marbles (many colors)

  • Dices

Preparation for the lesson:

The teacher should prepare a set of boxes, ensuring there are several identical boxes for each type.

Type 1: A match box with 1 dice inside

Type 2: A match box with 3 marbles inside, one white and the other two blue (we propose two diferent shades of blue)

Type 3: A match box with 4 marbles inside, 2 pairs of marbles with the same colors (we show a box with 2 red and 2 green marbles).

Figure 1. Examples of boxes of type 1 (left side), type 2 (center) and type 3 (right side).

Introduction

Data and Probability is fundamental to understanding today’s world, although not traditionally a core subject in early years mathematics. Simple games provide children with opportunities to explore random phenomena and their patterns, introducing ways of thinking and communicating about events characterized by uncertainty and chance.

Teaching and learning methods

Exploratory learning from an experimental set-up.

Interdisciplinary connections

Language – oral and visual communication.

Resource teacher or other specialists activities

Almost all the steps of the lesson are comprehensible to most special needs students who have well-preserved cognitive abilities. The lesson does not comprise written explanations, and the long instructions, which are difficult for the target group’s students (TGSt), are very few.

The role of the special needs teacher or the assistant teacher is to help TGSt in case they are not able to cope with some of the tasks or steps.

New vocabulary

Unlikely

Likely

Probable

Equally probable

Work Flow

Phase 1: Presenting the context (see appendix 1)

Children are presented to the three types of boxes. The teacher organizes the students into small groups (between 2 and 4 children). Each group is arbitrarily assigned a box. Each box is associated with a game.

Game 1: Close box type 1 properly, shake it for a few seconds and place the box upright so that the dice inside can rest against the bottom and top of the inside of the box (see figure 2). Open the box. If the sum of the points on the two exposed faces is even you win, if is odd you lose.

Figure 2. Example of outcome of game 1. In this case, the exposed faces are 4 (headed front) and 1 (at the top), whose sum is 5, an odd number - meaning the player loses the game.

Game 2: Close box 2 properly, shake it for a few seconds and place the box upright so that the marbles inside are aligned with the bottom of the box (see figure 3). Open the box. If the white marble is between the blue marbles you win, otherwise you lose.

Figure 3. Example of outcome of game 2. In this case, the white marble is between the blue marbles - meaning the player wins the game.
Game 3: Close box 3 properly, shake it for a few seconds and place the box upright so that the marbles inside are aligned with the bottom of the box (see figure 4). Open the box. If the red marble are together you win, otherwise you lose.

Figure 4. Example of outcome of game 3. In this case, the red marbles are alternated with the green ones meaning the player loses the game.

10 minutes

 

Phase 2: Formulating the problem

In this phase, each group has a box of one of the three types, so there are several groups for game 1, several for game 2 and several for game 3.  

Each group will have to analyze the game they have been assigned in order to answer the following question: Is the game fair?

At this stage, the teacher should discuss with the students what it means ‘a fair fair’, based on the understandings expressed by the students. They should realize that being fair means having equal chances of winning and losing. It is appropriate to use expressions such as ‘equally probable’.

The teacher can ask each group about the game they have been given, whether it seems, at first glance, fair or not and why.

10 minutes

 

Phase 3: Exploring the games

Now the working groups are invited to explore the game they have been assigned by repeating a set of trials, recording the result (win or lose) for each one. The roles of performing the trials and recording can rotate among all the members of the group so that everyone participates actively.

The registers can take the form shown in figure 5, or any other form with pedagogical interest. It is important that, in total, each group does a sufficiently large number of tests so that a pattern can emerge (lets say, 50 or 60 trials). Each pair of tester/recorder students can carry out a series of 10 tests, rotating these functions within the group. The other members should ensure that each trial takes place in a way to avoid bias.

Figure 5. Example of record of an hypothetical outcome of a set of 50 trials.

Teachers should bear in mind that, effectively, games 1 and 3 are fair, with the probability of winning equal to the probability of losing. In game 2 the probability of losing is substantially higher then the probability of winning, and thus game 2 is not fair (see annex 1). However, one should not forget that equal probability of results does not imply the mandatory equality of wins and losses when repeating the experiment a certain number of times. Chance, in itself, is unpredictable and the probabilistic model inherent to the random experience only reveals itself after a large number of repetitions. 

The example in figure 5 is perfectly plausible as a result of 50 repetitions of games 1 or 3. Only a very ‘well-behaved chance’ would produce 25 wins and 25 losses in 50 trials. However, for those willing to see, the fairness between wins and losses is there and will be so much more visible the higher the number trials. In a fair game, such as the cases of game 1 and game 3, one can expect a small advantage of either outcomes (win or lose) in a large set of trials. In the case of game 2 a significant difference between the number of gains and the number of losses is expected, with obvious benefit for the latter.

30 minutes

 

Phase 4:  Discussion of results

At this stage, the teacher asks the groups to share their results from each game. It may be interesting to combine the totals from the different groups that played each game to obtain overall totals for each one. With a larger number of trials, it is expected that the fairness or unfairness of the games will become more evident. The class should conclude that:

  •  games 1 and 3 are fair, while game 2 is not.

  •  in games 1 and 3, winning and losing are equally probable results.

  • In game 2 is more likely to lose than it is to win.

20 minutes

Reflection

Students should try to find an explanation for why games 1 and 3 are fair, while game 2 is not. To guide their reflection, the following questions can be asked for each game:

  • How many possible outcomes are there?

  • For how many we have a winner combination and for how many we have a loser combination?

Students get up from their seats and stand next to their desks/tables. The teacher explains to them that he/she is going to use his arms as the arms of an angle, and they must perform the corresponding action depending on how he places his arms. When:

• he/she stretches one arm out to the side parallel to the floor, at shoulder level, and raises the other up, students must lean back;

• he/she raises arms up and makes a "roof" above his/her head, students must lean forward;

• one of his/her hands points down to the floor and the other one points to the floor to the side, close to the body, students should squat.

If there is time, the activity continues with a student taking the teacher's place.

Relaxing Exercises senpower     15 - Moving like a toy

The teacher uses a magic word to change the students into many string-loaded (wind-up) toys. At the teacher’s signal, the toys start to move across the class, as many robots, to get their sits. They have to move more quickly at the beginning and then gradually more and more slowly, because their charge is finishing. Some of them will be frozen in the middle of the room, and the teacher has to give their cranks one more turn to help them reach their seats

Objectives

Students will:

  • consolidate their knowledge about the types of angles;
  • become familiar with the measurement unit for angles - degree - and its designation;
  • acquire the skills to measure the size of an angle with a protractor;
  • develop a positive attitude towards mathematics;
  • gain confidence in their capabilities;
  •  see the connection between mathematics and situations from their everyday life.

6. Print Handout 8 and cut the traffic lights separately. Each student needs one image of traffic lights.

Introduction

Have you looked carefully at the hour and minute hands of the clock? They form an angle that changes all the time.

In our daily life there are many objects in which we can find different angles – in the clothes hanger, the scissors, in a slice of our favorite pizza, etc. If you look closely, you will find angles in the letters and the numbers too. While doing various physical activities, we stand in a variety of poses, in which there are hidden angles as well.

Angles are all around us. And sometimes it is extremely important to know their exact size. Carpenters, for example, have to measure the angles very precisely when making a door, a table or a chair. Engineers construct buildings, bridges, monuments, etc., using angles of precisely defined sizes.

In this lesson, we will learn about the unit of measurement used to measure the size of an angle and learn how to measure angles using a protractor.

Work Flow

 Step 1 (5 min)

The lesson begins by updating students' knowledge of the geometric shape angle. The teacher opens the presentation from Annex 2 on shows slide 2 and asks students about the name of the shapes they see. On slide 3 students have to name the shape we receive when we have two rays with a common endpoint. The elements of an angle are remembered: vertex, arms and how an angle is named. The teacher then shows slides 4, 5 and 6 successively, students see the different types of angles. The class remembers the rule of how to determine the type of an angle using a drawing triangle.

Step 2 (5 min)

Students work in pairs with Handout 3. They outline with a solid coloured line the angles they find in the provided objects. They colour the circle for the corresponding type of angle. If needed, they can use a drawing triangle to determine the type of angles.

Step 3 (5 min)

Students receive Handout 4 for individual work. They have to record the result of the measurement of each object. The teacher remembers them that the length, height and width of an object can be measured in millimeters, centimeters, decimeters, or meters; the distance between two cities can be measured in kilometers; the mass of an object can be measured in grams, kilograms, or tons;  a period of time can be measured in seconds, minutes, hours, days, or years.

Step 4 (5 min)

Determining the size of an angle.

There is a special tool called a protractor. It is used to measure the size of an angle, and the measuring unit is called degrees. The topic is introduced by making use of the presentation from Annex 5. It shows different types of protractors and explains the most important elements. If a board protractor is available, the teacher can draw an angle on the board and demonstrate how to use it properly. If this is not possible, the teacher can demonstrate the procedure for measuring the size of an angle by showing slide 5 of the presentation. Slide 6 demonstrates how to measure the size of an angle that is open to the left.

Pay attention: when the angle is open to the left, the top set of numbers is used, whereas when the angle is open to the right, the bottom set of numbers is used.

Step 5 (10 min)

Students receive Handout 6.

  • In Problem 1, they have to identify the picture where the protractor is place correctly to measure the angle.
  • In problem 2 the task is to circle the answer with the size of the angle they see and mark the type of each angle. After completing the task, the teacher summarizes that a right angle measures 90º, the measure of an acute angles is between 0º and 90º, and the measure of an obtuse angle is between 90º and 180º.
  • In task 3 student have to find out the sizes of the angles and record the results.
  • In task 4 they have to measure the size of the angles using a protractor.
  • In Problem 5 students compare the angles measured in Problem 4.

Step 6 (20 min)

  1. “What type of angle am I?” Students line up in a circle. The teacher walks behind each one and attaches a sheet of paper with a right, acute or obtuse angle drawn on it. He/she can use sticky notes, having drawn angles in advance, or print out the angles from Handout 1 and attach them to students’ backs with paper tape.

One student stands in the centre of the circle. His task is to find out what angle he has on attached to his/her back by asking questions to the other students - only Yes or No questions can be asked: examples “Am I greater than a right angle?”, “Am I a right angle?”, “Am I smaller than a right angle?” etc. When the student has guessed the type of angle he has been assigned, he leaves the circle and points to a classmate to take the place in the centre. The game continues until all the students have taken their turn to be in the centre.

When a student guesses his/her type of angle and exits the circle, he stands next to the other students (if any) who got the same type of angle. Thus, at the end of the game, the students will be divided into three groups: "Right Angle", "Acute Angle" and "Obtuse Angle".

Tip: The number of images with each type of angle should be fairly equal to form groups of similar size.

2. Students work in the three groups. Each group gets one page from Handout 7 and a couple of straws. Students are advised to cut out the geometric shapes from the paper and use them for the head and body of their figure. The straws that each group received could be cut into pieces and used for arms and legs. The straws and the shapes should be glued on a white A4 sheet of paper so that the collage looks like the provided image. The team can colour their collage and draw additional elements. After making the person, each group identifies and measure the angles they see and fills in the information in the table.

Step 7 (2 min)

After completing the activity from Step 6, the teacher makes a short summary of the most important things in the lesson.

Reflection

Divide the class into two groups. One group, arranged in a circle, forms the fishing net. The remaining students are the little fish and will move freely around the room. The students in the net agree on a number without the little fish hearing them. They form a circle by holding hands and start counting in series (1,2,3...) until they reach the agreed number. The little fish know they can start moving when they see the wheel formed. When they reach the agreed number, they bend down and pick up the fish that remain inside the circle.

This exercise serves both to energise the students at the start of the lesson and as a transition to the lesson's theme.

Introduction

Geometric shapes are all around us. They are part of our daily lives. We're so used to them that we don't even see them as geometric shapes anymore, but just as objects. In this lesson, we'll learn how to draw circles with a compass and identify the centre of the circle. We'll also learn how to measure the radius and diameter of the circle. We'll also see how artists use the circle and circumference to create art and how these notions can be applied to scientific studies.

Teaching and learning methods

- Learning in small steps, reinforcing instructions in smaller chunks that cater for students' different starting points and learning rhythms.

- Applying the experimental method. Learning through visualisation, experimentation and manipulation.

- Using group work for co-operative and collaborative learning.

- To raise awareness of what is being learnt, encourage learning based on concrete situations that are close to the students.

- Using new technologies to learn about and consolidate content.

Interdisciplinary connections

Mother tongue - oral skills in order to interact appropriately in the context and for various purposes (namely, explaining knowledge, presenting narratives, arguing based on points of view).

Artistic expressions - interpretation and communication - the aim is, in a systematic, organised and comprehensive way, to develop apprehension and interpretation skills in contact with different visual universes (...) and to develop strategies for building relationships between looking, seeing and doing.

Resource teacher or other specialists activities

This lesson favours the step-by-step method, with short, clear instructions.

The role of the special education teacher or support teacher is to supervise and help, when necessary, in carrying out some of the tasks or steps (for example, the rotation of the compass can be difficult and the teacher needs to help with this).

The teacher can sit next to the student(s) and clearly repeat words or reinforce directions when they are not understood.

New vocabulary

Circle, circumference, centre, radius and diameter;

Work Flow

1st Step - Large group

Introducing the topic.

Explain that in the lesson students will learn to distinguish between a circle and a circumference and learn more about this geometric shape.

We will also see how artists use geometric shapes to create art.

2nd step - identifying circles and circumferences

The teacher asks the students to look around and name objects in the classroom where they can identify circles and circumferences: glue sticks, pencil cases or other details on their rucksacks. Students can also name other objects in their daily lives. Let all the students name their discoveries.

Recall geometric shapes and solids, focussing on the circle made during the initial game - energizer. Distinguish between the line made by the students (circumference) and the space inside that line (circle).

You could also show short videos on how to draw circles on the internet.

3rd Step - Individual

"Shall we find the centre of the circle?"

Task 1: The teacher distributes a square of paper to each student. He then asks the students to use their compasses and with the ruler measure the opening of the compass at 5 cm. Each student draws a circle. The students cut out the figure.

At this point, the teacher shows the students a larger cardboard circle, which they can place in a visible place for all the students and use as a model for the following tasks.

Task 2: The teacher explains the following folding sequence step by step. First, he folds the circle into 4 equal parts, first in half and then in half again, always aligning the line of the circle. Discuss what they observe. The students repeat the procedure, step by step, at the same time as the teacher.

Unfold the sequence and look at it.

Here they can count how many parts the circle has been divided into, how many lines they can see and where they join.

*Here you can talk about fractions of the circle (reviews ½; ¼ ).

Task 4: Identify the names and cover the lines in the picture with the colours assigned in a stipulated code. The teacher does it on the model and the students repeat it on their picture. (Appendix 2)

Example:

- centre: 1 blue dot

- circumference: green

- circle: yellow

- diameter: orange

- radius: red

Task 5: This work can be pasted into the student's individual notebook, or it can be displayed on the board.

3rd  Step - Large group

Conclusion

Circles and circumferences in art and life.

Art: The teacher shows the first two slides from Appendix 3: Geometry and Art Powerpoint. He explains that the images are paintings by Kandinsky and Miró and that they used the circle and the circumference in their art.

Geometric shapes in life: The teacher shows the following slides with images of different objects where the circle and circumference appear in everyday life: bicycle wheel, basketball hoop, pizza, monuments...

4th Step - Suggested activity

Encourage the students to put themselves in the place of the artists. They can use the compass to create their works of art.

They can also use toilet roll or kitchen roll and paint to make a picture with different coloured circles.

It could be suggested that the class continue to discover different objects at home that resemble the new geometric shapes.

If the school has tablets, allow the students to research more about the circle in monuments or other constructions... 

Reflection

The teacher can ask the students:

- "What do you think you learnt that was important today?"

- "What did you enjoy learning the most?"

- "Which activity did you enjoy the most?

   - Relaxation activity

   - Group dynamics - Game

   - Large group activities

   - Individual activities

The teacher helps to summarise the information by asking the students to consult the poster on the board whenever necessary.

- file with problem situations (how much money they have, what they need to buy and whether they need more products)

- paper notes and coins to print out

- supermarket leaflets

Preparation:

1. preparing packages or empty product packaging

2. cut out labels with prices and promotions

3. print some paper notes and coins

4. print a problem file

5. create a "sales stall" visible to all the students

Introduction

Using money is part of our daily lives. We need it to buy what we  eat, wear, put on and also for leisure activities. In this lesson, we'll learn how to identify notes and coins. We'll also see how to make the right choices that allow us to save, make change and even apply discount percentages, based on representations of real situations.

Teaching and learning methods

Learning in small steps, reinforcing instructions in smaller chunks that provide for students' different starting points and learning rhythms.

Applying the experimental method. Learning through visualisation, experimentation and manipulation.

Using group work for co-operative and collaborative learning.

- To raise awareness of what is being learnt, encourage learning based on concrete situations that are close to the students;

Using new technologies to learn about and consolidate content.

Interdisciplinary connections

Mother tongue- Oral skills (comprehension and expression) with a view to interacting appropriately in the context and for various purposes (namely, explaining knowledge, presenting narratives, arguing on the basis of points of view).

Citizenship and development - Financial education.

Resource teacher or other specialists activities

All the steps in the lesson are understandable for most students with special needs. The lesson doesn't include long written explanations and there aren't many long instructions that are difficult for students in the target group (TGSt).

The role of the special needs teacher or assistant teacher is to check that the student is able to understand the stages of the simulation of real situations and to help organise their thinking in order to carry out the calculations.

New vocabulary

Discount percentage, change, promotion.

Work Flow

1st step - large group

Introduction to the topic

The teacher begins the lesson by explaining that the students will be simulating everyday situations involving the buying and selling of products.

Before starting the simulation, the teacher introduces the notes and coins, mentions their value and can also show equivalences in value by showing the students the coins and notes one by one. (Appendix 1) on printed paper and powerpoint presentation).

2nd step - Pair Work

The teacher asks the students to pair up with the classmate next to them or the one closest to them, and hands out a set of notes and coins which the students cut out and manipulate (Appendix 1A), experimenting with the equivalence between notes and coins.

The teacher asks questions to explain and  to challenge the class.
e.g. How many notes of 5€ do you need to have the same value as the 20€ note?

3rd step - Small groups work

Practical activity

The students get into groups of 4 or 5.

The teacher introduces the ‘stall’, a table prepared in advance with boxes, empty packaging and clippings from supermarket leaflets and various price tags (appendix 2) (including discounts: 50% / take 2 pay 1...).

Each group is invited to look at the ‘stall’ and make a shopping list on a white sheet of paper according to what is on display.  Then two members of each group get up and go shopping, collecting what's on the list from the stall.  With the participation of all the members of the group, they do the calculations to pay the teacher, who is the owner of the supermarket and who will collect the money.

For the groups that have finished, the teacher can provide a problem situation from Appendix 3.

4th step - Individual

Proposal to solve an individual mini formative test (appendix 4)

Reflection

The teacher summarises the information given in class and helps students to think about the best option to take in a real-life situation, for example when shopping with their parents. As a family activity, the teacher can ask the class to make a visit to a market or shopping centre where they can take part, see and reflect on smart and more economical options.

At the end of the lesson the teacher can ask the students:

"What do you think was the most important thing you learnt today?"

"Which activity did you enjoy the most?

"How do you think what you learnt today could be useful in your day-to-day life?"

Energizers senpower     7 - Connecting eyes

Participants stand in a circle. Each person makes eye contact with another person across the circle. The two walk across the circle and exchange positions, while maintaining eye contact. Many pairs can exchange at the same time, and the group should try to make sure that everyone in the circle is included in the exchange. Tip: Begin by trying this in silence and then exchange greetings in the middle of the circle.

Variations: If the teacher considers, knowing the class atmosphere, that some students might be left not participating, i.e. they try to make eye contact but nobody responds to them and they have no chance to move from their initial position, the moderator could divide the class in 2 groups and introduce a competitive element – after the activity each group will be marked on the ‘team spirit thermometer’ (which could be printed on a A4 paper and the teacher marks the degrees with a marker). The more people you have left not participating in the ‘eye contact’ activity – the lower the degrees to be marked on the thermometer.

Everyone stands in a circle. One participant closes his/her eyes or steps out of the room. He/She will have to guess who is the chief of the clan. One participant volunteers to be the secret Chief (quietly, so the "guesser" can't hear anything). The chief begins an action such as snapping fingers, patting the tummy, or slapping knees, and everyone in the circle imitates him/her.  The guesser returns to the room and tries to figure out who the chief is. As the guesser looks around, the chief changes the action avoiding being detected.

Resource teacher or other specialists activities

The steps in the lesson are comprehensible to most students with special needs who have well-preserved cognitive abilities. The text and instructions of the tasks are short and clear. The role of the support teacher is to help students if they don’t understand the instructions.

New vocabulary

There is no new vocabulary in the lesson.

Work Flow

1. The lesson begins with updating students' knowledge and skills for multiplying numbers similar to: 3x4, 3x40, 3x400 and 3x4000. The teacher distributes Handout 1 to each desk/table. He/she may have cut the circles from page 2 or leave this activity to the students. In each column of the provided tables, students should stick the correct number of circles in order to present the second multiplier in the products (the first multiplier equals to the number of columns of the tables). For example, to visualize the product 3 x 4, in each column of table (a) there should be glued 4 circles with number. After that, students calculate/count the number of ones, tens, hundreds and thousands in each table and fill in the missing numbers in the products.

Students could play the online games:

https://wordwall.net/resource/70937847  and

https://wordwall.net/resource/70938027 .

When doing the second game, the teacher can name a student to report the answer and then turn over the card to check the given answer. In case of a mistake, a comment is made and the teacher explains how to get the correct answer. (10 min)

  1. Distribute Handout 2 to each student.

In task 1, in each column of the corresponding table, students have to colour as many circles as the number of specified ordinal units in the first multiplier of the product. After that, they fill in the entry the table below and calculate using the distributive property of multiplication linked to addition.

In task 2, students again use the distributive property of multiplication linked to addition by writing in the cells the result of the multiplication element by element (multiplying the ones, after that – the ten, after that – the hundreds, etc) and then, all the products are added together. (10 min)

3. The teacher opens the presentation from Annex 3 and sets the task from slide 2. The students read it and suggest ways of solving it. It is concluded that in order to solve the problem, one has to calculate the product of the numbers 1242 and 2. The teacher shows how you can easily calculate mentally the product of a multi-digit number with a single-digit number without carrying (slide 3). Slide 4 presents the written algorithm for calculating products. Remember students to start the multiplication starts from the ones (Step 1).

(5 min)

4. The teacher distributes Handout 4 to each student.

In task 1 students have to calculate the products.

In task 2 they have to calculate the expressions.

In task 3 students have to calculate the expressions and compare their values.

Problems 4 and 5 are word problems where they have to use multiplication.

  1. The lesson begins by updating students' skills of multiplying a multi-digit number by a two-digit number.

The teacher distributes Handout 1 for individual work. If necessary, the multiplication algorithm is remembered to the class by having a student to demonstrate it on the board and providing relevant explanations by the teacher.

In task 1 students have to complete the intermediate products by writing the missing numbers.

In task 2 they have to calculate the products, find the answer among the provided numbers and color the box with the problem in the same colour as the box with the result.

In task 3 they calculate the products, compare the result with the number 100,000, and match it to correct one.

Various e-games and resources can be used to launch the lesson, e.g. https://www.mathgames.com/skill/4.120-multiply-a-2-digit-number-by-a-2-digit-number

or https://wordwall.net/resource/36987646/math/2-digit-by-2-digit-multiplication (10 min)

2. The teacher explains that information can be presented in different ways - with drawings, diagrams, charts, tables, etc. This is demonstrated with the presentation from Annex 2. At the discretion of the teacher, some of the tasks given as examples may be solved. (5 min)

3. The teacher distributes Handout 3 to students and opens the handout on the screen. The tasks are solved as a whole-class activity with the corresponding comments being made; students record the solutions on their worksheets. (10 min)

4. The teacher distributes Handout 4 to each desk/table. Students use the provided pictorial information and do the tasks.

In task 1 they have to extract information represented in the pictures and represent it using a pie chart.

In task 2 students have to extract information from a pie chart and fill in the missing numbers in the text.

In task 3 they have to extract information from a table and present it using a block graph.

In task 4 students have to compose a word problem using the information from the pictures, and solve the problem. Pairs volunteer to read the word problems they have created for the rest of the class solve them. (10 min)

Reflection

The teacher could collect feedback about the different ways of presenting information and, at the same time, sum them up, by the following questions and activities:

  1. Print Handout 5 in several copies, cut the pictures separately and pile the same picture together in 6 piles. Ask students to choose the picture they have seen somewhere (on TV, in a book, on the Internet, etc.) and get ready to describe the case. When ready, they come up to the front, show their picture and tell the class the details of their story. The teacher could look up for examples from the internet, and show them to the class.
  2.  Put the 6 picture cards from Handout 5 in 6 locations in the classroom, and ask students to go to the one with their favourite way of presenting information. When the 6 (or less, in case nobody chose some of the pictures) groups are formed, students share within their groups why they like this way of presenting information.

Explain to the kids the process of the water cycle (evaporation, condensation, precipitation) in simple terms.

Play some music and have the kids dance around the play area. When the music stops, call out one of the water cycle stages.

When a stage is called out, the kids must quickly freeze in place, acting out the corresponding stage (e.g., spinning to represent evaporation or forming a group to mimic precipitation).

Continue playing the music and calling out stages intermittently.

Relaxing Exercises senpower     26 - Raindrops

Close your eyes and imagine that you are a water drop that falls in the ocean when it is raining. Imagine how you can return to the cloud due to the water cycle process.

Objectives

Students will:

  • (Nature Science) Establish correspondence between changes in the physical state of water (evaporation, condensation, solidification, melting) and the conditions they result from within the water cycle.
  • (Mathematics) Interpret and model situations with varying quantities and solve associated problems.
  •  (Science and mathematics) Understand why we use millimetres as a measuring unit to measure precipitation.

  2.  Read this information to learn more about urban flooding: What Is Urban Flooding? (nrdc.org)
Introduction

For the teacher:

This interdisciplinary lesson plan aims that students explore the quantity used to measure precipitation by doing hand-on experiments. When primary school students are asked about how to measure the rain falling from the clouds, many of them would answer that volume is the proper quantity to measure it. However, volume does not allow comparisons between the quantities of rain that fall in different regions, whereas millimetres do. The lesson plan follows the inquiry-based learning approach.

Start the Part II by presenting the news from Annex 1 to students. Then ask the question: How is rainfall measured?

Collect their initial ideas. They might say that volume is a good idea to measure rainfall. At this stage you accept all answers. Next, engage students in the following experiment.

What you need:

  • 5l square plastic bottle
  • 1,5l plastic bottle
  • 1l plastic bottle
  • 0,33l plastic bottle
  • 1 large tray
  • 3 beakers
  • 1 ruler

Observation: Some bottles must have a round cross section while others should have other shapes (Figure 1).

Figure 1. Plastic bottles with different shapes (Source: Freepik).

Instructions:

  1. Drill 30 holes in one of the larger surfaces of the 5L plastic bottle.
  2. Cut the top part of three plastic bottles with different capacities. The remaining height must be 15 cm.
  3. Put the three plastic bottles on the tray with the top up.
  4. Fill carefully half of the 5l plastic bottle with water.
  5. Simulate precipitation for one minute by turning the perforated surface of the 5l plastic bottle over the plastic bottles you cut in step 2.
  6. Measure the height of the columns of water in each bottle (Figure 2).

Figure 2. Model of the experiment.

  1. Ask students to measure the height of the water column in each plastic bottle.
  2. Ask students to measure the volume of water in each plastic bottle (by using a measuring pot or by comparing the volumes).                                           30 min

Discussion:

  • Ask students if the volumes of water of the 3 plastic bottle are the same or different.
  • Ask students if the height of the columns of water of the 3 plastic bottle is the same or different.                                                                                            10 min

Conclusion

The main observation from this experience is that volume is not a good measure for rainfall because volume varies according to the area of the cross section of the plastic bottles. The height of the columns of water does not vary between the recipients, and that is the reason why millimetres of column of water is a better measure for rainfall. Moreover, millimetres of the column of water allows comparison of precipitation between different zones.                          5 min

2 senpowerInterdisciplinary lessons / Water: Flooding in urban environment
Developed by IPSantarem - Bento Cavadas e Nelson Mestrinho
Grade 3
Duration 50
Energizers senpower     28 - Water cycle

Explain to the kids the process of the water cycle (evaporation, condensation, precipitation) in simple terms.

Play some music and have the kids dance around the play area. When the music stops, call out one of the water cycle stages.

When a stage is called out, the kids must quickly freeze in place, acting out the corresponding stage (e.g., spinning to represent evaporation or forming a group to mimic precipitation).

Continue playing the music and calling out stages intermittently.

Preparation for the lesson

  1. You should create the tray flooding setting before the experiment.
  2.  Read this information to learn more about urban flooding: What Is Urban Flooding? (nrdc.org)
Introduction

Climate change consequences, such as flooding, are a major problem for many European cities.

Flooding typically occurs when prolonged rain falls over several days, when intense rain falls over a short period of time, or when an ice or debris jam causes a river or stream to overflow onto the surrounding area. Flooding can also result from the failure of a water control structure, such as a levee or dam. The most common cause of flooding is water due to rain and/or snowmelt that accumulates faster than soils can absorb it or rivers can carry it away (National Weather Service).

According to the Federal Emergency Management Agency (FEMA), urban flooding is “the inundation of property in a built environment, particularly in more densely populated areas, caused by rain falling on increased amounts of impervious surfaces and overwhelming the capacity of drainage systems.”

In this lesson you are going to explore urban flooding causes and consequences with primary school students.

Work Flow

  • Start the lesson asking students what they know about flooding. Then, explain that flooding typically occurs when prolonged rain falls over several days (1), when intense rain falls over a short period of time (2), or when an ice or debris jam causes a river or stream to overflow onto the surrounding area (3). Flooding can cause many damages in cities due to bad drainage systems.
  • Watch the video with the students: FLOODS - The Dr. Binocs Show | Best Learning Videos For Kids | Peekaboo Kidz - YouTube

Part II | Rainfall and urban flooding

  1. Start Part II of the lesson presenting information about recent news related to flooding using the online page FloodList. Then ask them to think and suggest answers to the question: Which are the causes of urban flooding? Collect their initial ideas without making comments. It is expected that all answers will be linked to heavy rain as a major cause.
  2. Experiment
  • What you need:

  • Lego®
  • 1 large tray
  • Small debris (organic, plastic, other)
  • 1 strainer
  • 5 l plastic bottle
  • Measuring cup or graduated cylinder
  • Glue
  • Instructions:

Phase 1 | Simulation of rainwater drainage in a city, without rainwater blockage

  • Cut a hole at one of the corners of the base of the tray, so that the strainer can pass through.
  • Carefully attach the strainer to the hole using glue.
  • Put a measuring cup or a graduated cylinder under the strainer, as indicated on Fig. 1.
  • Ask students to create a Lego® city.
  • Put the Lego® city inside the tray (Fig. 1).
  • Simulate precipitation during one minute by turning the perforated surface of the 5l plastic bottle over the Lego city (Fig. 1).

Figure 1. Model of the experiment.

3. After the drain water falls into the plastic bottle or the measuring cup, the students should count the time in order to mark on the plastic bottle or measuring cup (e.g. using a marker), the amount of water that drained during the first minute, then during the second minute, and so on, until no more drain water flows.

4. Ask students to measure the amount of water inside the plastic bottle, or if they use a measuring cup – to calculate the amount of water, identifying the amount corresponding to each minute. The data can be registered in the table (Annex 1):

Phase 2 | Simulation of blockage on rain water drains

  1. Repeat the procedure of phase 1, but add some organic debris (leaves, food waste, etc) inside the strain - this is going to simulate the blockage of rain water drain.
  2. Repeat the procedure of phase 1, but add some small plastic debris (plastic bags, plastic bottles, etc.) inside the strain - this is going to simulate the blockage of rain water drain.

Phase 3 | Simulation of heavy rain

Simulation of normal rain:

  1. Repeat the procedure of phase 1, but add a mixture of organic and plastic debris inside the strain - this is going to simulate the blockage of rain water drain.
  2. Observe what is going to happen to the level of water in the Lego® city.

Simulation of heavy rain:

  1. Drill 50 holes in one of the larger surfaces of the 5L plastic bottle.
  2. Repeat the procedure of phase 1, but add a mixture of organic and plastic debris inside the strain - this is going to simulate the blockage of rain water drain.
  3. Observe what is happening to the level of water in the Lego® city.
  4. Compare the water level in the Lego® city when you have normal rain with the water level of heavy rain.
  5. Describe what happened to the Lego® city in the two cases.

30 min

Discussion:

  • Ask students what happened when the rain water drain was not blocked.
  • Ask students what happened when the rain water drain was blocked by debris.
  • Ask students what happened when the heavy rain dropped in the Lego® city, in comparison with normal rain.
  • The various tables relating to the different simulated situations can be represented graphically, providing an image of the evolution of the rainwater runoff for each situation.

                                           Example of a hypothetical graphical representation.

20 min

Conclusion

The main idea of this experiment is that students understand better the causes of urban flooding.  One cause is the blockage of rainwater drains. Another cause is heavy rain in a short period of time. At the same time, students will have the opportunity to use mathematical language to quantitatively represent, describe and interpret phenomena arising from the experimental environment, with obvious connections to the subject under study - urban flooding.

3 senpowerInterdisciplinary lessons / Measuring human footprints
Developed by IPSantarem - Bento Cavadas e Nelson Mestrinho
Grade 3
Duration 30
Energizers senpower     48 - Movement

Part I

The teacher asks the students to form pairs and gives each pair a piece of paper and a pencil. Then, each student should trace their right footprint on the paper and write their name next to it. Afterward, they should observe both footprints and identify which one is larger.

Part II

Teacher says to the students: “So today, let’s walk, run, or jump with energy!”. Students should move around, walking, running or jumping at the sound of a previous music chosen by the teacher. 

Relaxing Exercises senpower     31 - Triangle of friendship

Students work in pairs to draw a triangle to represent their friendship. Before starting the work, the teacher demonstrates the steps with one of the children. The two persons in the pair place their hands down with the palms facing the surface of the paper sheet; student 1 uses his/her right hand, and student 2 uses his/her left hand.  They join the tips of the thumbs and the forefingers of the left hand of one of the pair with the tips of their thumbs and forefingers and outline the shape of the triangle between the fingers. After that, they can draw eyes, a nose, a mouth and whatever they want to, in order to design a personal symbol of their relationship.

Objectives

Students will:

  • Improve their measuring capabilities.

  • Understand that the diversity of human footprints is related with the diversity of the human body.

Preparation

Materials

Paper (A4) and markers

Ruler (to measure footprints)

Measuring tape (to measure the height of the student)

Introduction

Human footprints are more than just traces left behind in the ground. They are a symbol of our existence and interaction with the world. From ancient times to the present, footprints have represented our journey, movement, and impact on the environment. In a literal sense, they are physical marks that record our presence, whether on a sandy beach, muddy path, or snowy terrain. 

On a broader scale, human footprints also represent our "footprint" on the planet. This includes our contributions to climate change, deforestation, and biodiversity loss, as well as the cultural and historical traces we leave in art, architecture, and innovation. Understanding human footprints, in both their physical and metaphorical forms, helps us reflect on our relationship with nature, the consequences of our actions, and the paths we carve for future generations.

This is a mathematics and science interdisciplinary activity because it connects measurement with the human body.

4 senpowerInterdisciplinary lessons / Dinosaur locomotion
Developed by IPSantarem - Bento Cavadas e Nelson Mestrinho
Grade 3
Duration 2h30
Energizers senpower     45 - The dinosaur energizer

Ask each student to think of their favourite dinosaur and be ready to share it with the class. Then, organize the students in a straight line, standing side by side. Now, each student should imitate the dinosaur movement following these steps:

  1. One by one, each student will announce their favourite dinosaur.

  2. After announcing, the student will move across the room, imitating the locomotion of their chosen dinosaur (e.g., stomping like a T-Rex, flying like a Pterodactyl, or lumbering like a Brachiosaurus).

  3. The rest of the students will observe carefully the different movements.

After everyone has had a turn, gather the students for a brief discussion. Ask them to share what they noticed about the different types of dinosaur movements. Discuss how the structure and size of each dinosaur might have influenced its way of moving.

As an alternative:

If the school has a large enough sandpit, a short activity could be organised to make students realise the relationship between the way humans move and the marks registered on the ground. This activity would consist of asking students to freely produce footprints in the sand as a result of walking (A) or running (B) (Figure 3). 

Figure 3. Walking and running footprints.

The aim of this exploration would be to realise that the higher the speed of movement, the further apart the footprints tend to be arranged on the track, as well as more aligned (B), as opposed to walking, where consecutive footprints tend to be closer together and more side by side (A).

Some engaging questions are:

  • What happens to our footprints when we walk slowly? Do they get closer or further apart?

  • And when we start running, does the distance between our footprints increase or decrease?

At this stage the teacher can organise a more structured demonstration, with a chosen student, to compare the two situations.

Relaxing Exercises senpower     40 - Guided fantasy with dinosaurs

Close your eyes and take a deep breath in. Slowly exhale and feel your body relax. Imagine that you are in a lush, green prehistoric landscape filled with tall trees, colourful plants, and the distant sounds of gentle dinosaur calls.

In your mind, picture a gentle, friendly dinosaur, like a Brachiosaurus or a Triceratops, peacefully grazing or moving through the landscape.

Notice the dinosaur’s size, shape, and the way it moves slowly and gracefully. Imagine the texture of its skin and the calm look in its eyes. Relax the most during this exercise.

Objectives

Students will:

  • (Science) Identify plants and animals that are endangered or even extinct, investigating the reasons that led to this situation.

  • (Mathematics) Measure lengths using appropriate measuring instruments, expressing measurements in metres and centimetres, represented using decimals.

  • (Science and mathematics) Understand how mathematics can be mobilized to identify characteristics of dinosaurs

Preparation

Materials

Dinosaur (theropod) footprints (Appendix 1)

Equipment

Laptop and projector or interactive board

Preparation for the lesson

  1. The teacher should create a dinosaur footprint track before the lesson. The track can be made up of 6 to 8 (or more) footprints. Consecutive footprints must be at the same distance from each other, as shown in the diagram below (Figure 1).

Figure 1. Dinosaur footprint track.


If you prefer to organize the activity in an indoor setting, like a corridor, a hall or a porch, you can use footprints printed on paper (see annex I). As an outdoor alternative, you can adapt the footprint by turning it into to a template and use it to draw them on the ground.

  1. The foot length, pace length and stride length must be identifiable in order to be measured by the students on the track (Figure 2). 

Figure 2. Foot length, pace length and stride length.

For a footprint length which is between 22 and 24 cm (don’t exceed 25 cm), you can use a stride length of about 2,50 m.

Introduction

Dinosaurs are among the main focuses of young students’ conceptual interest. Studying dinosaur footprints and tracks can raise their awareness of ancient animals and the causes of their extinction. Although the approach to the study of dinosaur tracks proposed in this work is simple, it must be done with great rigor, bearing in mind that measuring correctly the footprints is a must.

Part I | Dinosaur extinction

Start the lesson asking students what they know about dinosaur extinction.

Ask them to explore the following online pages:

Then, ask students to identify if their initial ideas are similar to the reason for dinosaur extinction proposed by science. To promote discussion, the teacher can ask students some of the following questions: 

  • How long have dinosaurs been extinct?

  • Which is the man cause proposed for dinosaur extinction?

  • How do you think the world changed after the dinosaurs went extinct?

  • Why is it important for us to learn about dinosaur extinction? Why?

  • How do you think the extinction of dinosaurs affected other animals and plants?

  • If dinosaurs were still alive today, how do you think our world would be different?

  • Do you think it's possible that another mass extinction might happen? Why or why not?

Part II | Dinosaur size and dynamics

Step 1: Get to know the footprint track - Appendix 1

Students are taken to the site where the footprint tracks were created. They are told that the trackway is a record of dinosaur's activity in the distant past and that we can extract information from it about the dinosaur's characteristics and behaviour. The simulated track is similar to real tracks that can be found around the world (Figure 4).

C:\Users\Bento\AppData\Local\Microsoft\Windows\INetCache\Content.Word\Pegadas de vale de Meios_1.jpg

Figure 4. Dinosaur footprint in Alcanede, Portugal.

The tridactyl footprints indicate that they were produced by a theropod dinosaur. 

At this stage it makes sense to ask the students what additional information this track can provide. What characteristics of the track can be measured?

For example, the length of the footprint, which gives us information about the size of the animal, can be measured.

Students are asked to organise themselves in pairs to measure and record the length of the footprint. Here are some aspects to take into consideration by the teacher:

  • All the footprints should be the same length, considering that they come from the same individual (invariance).

  • Students should carefully measure the length of the footprint, consisting of the distance between the heel and the end of the big toe, as shown in the diagram below (Figure 5). 

Figure 5. Foot length.

Students can use a ruler to measure, as it is a short length. They can also use a tape measure, which they will need later to measure the other parameters of the track.

  • Measurements taken by different students may vary slightly. The measurement process, being rigorous, is never exact, due to errors arising from different factors that cannot be eliminated, for example he limitations of the measuring instrument or the operator himself. The teacher should supervise the implementation of the measurement process done by the students to ensure rigour but should also allow each group to work with their own measurement if they don't vary too much (the difference should not exceed 1 cm). These differences, and what will result from them, can be explored didactically during the final discussion at the end of the activity.

  • The length of the footprint can be recorded using different levels of accuracy, ranging from a measurement to the nearest centimetre or millimetre, expressed in metres (standard unit) or centimetres, using integers or decimals. For example, the length of a footprint 23 cm and 5 mm long can be represented as 23.5 cm, or 0.235 m or 235 mm.

After measuring and recording the foot length, the working pairs should recognise two other parameters of the track, namely the pace length and the stride length, according to the following diagram (Figure 6)

Figure 6. Foot length, pace length and stride length.

Students are also required to measure and record these two elements of track data. The pace length should be understood as the distance between two consecutive footprints, measured from heel to heel; stride length as the distance between two consecutive footsteps of the same foot, also measured between two corresponding points (as before, for example, from heel to heel).

Again, it’s important to realise that: 

  • The pace length is approximately, but not exactly, half the size of the stride length. 

  • The stride length, which is related to the pace length, is an indicator of how fast the dinosaur was moving – The longer the stride, the faster it moved.

  • The considerations outlined above for the foot length are equally valid now for the pace length and the stride length.


Step 2: Interpreting the data to understand size and type of locomotion

At this stage of the work, students will have the opportunity to obtain simple but relevant additional information about the theropod dinosaur from the data collected, just by using simple mathematical models.

The size of the footprint gives us an idea of the size of the dinosaur that produced it. An important parameter is the size of the leg, usually referred to as the hip height, is an indicator of the size of the dinosaur (Figure 7)

Figure 7. Hip height (H).

For a small theropod (with a foot length of less than 25 cm), the hip height can be estimated by multiplying the footprint length by 4.5. Students must now multiply their measurement for the foot length by 4.5 to determine the hip height of the dinosaur. 

Stride length tells us whether the dinosaur moved faster or more slowly: the longer the stride, the faster it moved. However, this is relative, depending on the size of the leg, which in this context we call hip height. This means that a certain stride length could mean faster displacement for a dinosaur with shorter legs, or a slower locomotion for a dinosaur with longer legs. For this reason, discovering the type of dinosaur locomotion responsible for the trackway involves assessing the stride length in relation to the hip height. So, students must divide the value of the stride length (measured on the track) by the hip height (determined in the previous step). If this ratio is found to be:

  • Less than 2, then the dinosaur was walking

  • Greater than 2.9, then the dinosaur was running

  • Is between 2 and 2.9 (including this values), then the dinosaur was trotting.

In this case, as a reference with a stride length of 250 cm, for a footprint of 24 cm, the hip height would be:

Hip height=4,5 × foot lenght=4,5×24=108 cm

After obtaining this value, the students can use a tape measure to represent what this dinosaur's hip height would be and imagine how tall the dinosaur was.

Then, they should calculate the dinosaur locomotion, as in the following example:

Dinosaur locomotion=Stride length : Hip height= 250 : 108=2.3 (Dinosaur was trotting)

To carry out the division, the teacher can authorise students, if considered appropriate, to use a calculator or, alternatively, engage in “pencil and paper” calculation (algorithm) or use any other calculation strategies, according to the level of the students. It is not important to achieve an exact result, but only an approximation that allows the ratio to be compared with the reference values provided (2 and 2.9).
