Objectives (5 - 7 minutes)

1. Understand the concept of sharing and equal parts: Teach students what it means to divide something into equal parts. This involves the idea that each part has the same value and that, when all parts are put together, the whole is obtained again.
2. Apply the concept of sharing in practical situations: Provide students with the opportunity to apply this concept in everyday situations. This may include dividing objects, food, or tasks among a group of people.
3. Develop problem-solving skills: Promote critical thinking and problem-solving through activities that require the application of the sharing concept. This includes the ability to identify and solve problems, make predictions, justify solutions, and reflect on the problem-solving process.

Introduction (10 - 15 minutes)

1. Review of previous contents - The teacher starts the lesson by reviewing two fundamental concepts for understanding sharing: the concept of "whole" and "parts". He can use visual examples, such as a whole pizza (the "whole") and pizza slices (the "parts"), or a box of pencils (the "whole") and individual pencils (the "parts"). The teacher can ask the students how many parts they see and if all parts have the same value.

2. Problem Situation 1 - The teacher proposes the following situation: "Imagine you have 12 candies and want to divide them equally among your 3 friends. How would you do that?" Students are encouraged to think about the solution to the problem.

3. Problem Situation 2 - The teacher presents a new situation: "Now imagine you have 10 cookies and want to divide them equally between you and your brother. How would you do that?" Students are once again challenged to think about the solution.

4. Contextualization - The teacher explains that sharing is an important skill in everyday life. He can cite examples such as sharing toys, household chores, food in a family meal, among others. He can also mention that sharing is used in many professions, such as in a bakery that needs to divide a cake into equal slices, or in a store that needs to distribute a batch of products among the shelves.

5. Introduction of the theme - The teacher introduces the concept of sharing and equal parts, explaining that when we divide a whole into equal parts, each part has the same value. He can use a visual example, such as a chocolate bar, to demonstrate that when the bar is divided into equal parts, each piece is the same size and has the same value.

Development (20 - 25 minutes)

The teacher can choose one or more of the following practical activities to develop the concept of sharing and equal parts. The activities are designed to be playful and engaging, encouraging active student participation and the development of problem-solving skills.

1. "Treasure Sharing" Game (10 - 15 minutes)

   • The teacher distributes a box with "treasures" (for example, seashells, colored stones, buttons, etc.) among the student groups.
   • Each group must then divide the "treasures" equally among its members.
   • The goal is for all group members to have the same number of "treasures".
   • Students are encouraged to think of different ways to share and discuss in the group what the best strategy is.
   • At the end, students should present to the class how they solved the problem and if everyone got the same amount of "treasures".

2. "Snack Sharing" Activity (10 - 15 minutes)

   • The teacher divides the class into small groups and distributes a box with "snacks" (for example, cookies, grapes, carrot sticks, etc.) to each group.
   • The task for students is to divide the "snacks" equally among the group members.
   • The teacher can propose different quantities of "snacks" for each group, challenging them to think of different ways to share.
   • At the end, students are encouraged to share their strategies and discuss if all parts received the same amount of "snacks".

3. "Time Sharing" Activity (10 - 15 minutes)

   • The teacher proposes a situation: "You have 20 minutes to play a game. How would you divide this time among all group members?"
   • Students are challenged to think of different ways to divide the time equally and discuss what the best strategy is.
   • The teacher encourages students to consider the opinion of all group members in decision-making and to reflect on the importance of cooperation and mutual respect in sharing.

These activities allow students to apply the concept of sharing in a practical and playful way, promoting understanding and internalization of the concept.

Feedback (10 - 12 minutes)

1. Group Discussion (5 - 6 minutes)

   • The teacher gathers all students in a circle and starts a group discussion. Each group is invited to share the solutions and strategies they found during the activities.
   • The teacher encourages students to explain their choices and reflect on what they learned from the activity. He should ask guiding questions to stimulate the discussion, such as: "Why did you choose this sharing strategy?" or "What did you find most challenging in the sharing activity?".
   • During the discussion, the teacher makes connections between the strategies used by different groups, reinforcing the concept that there are several ways to divide something equally.

2. Individual Reflection (3 - 4 minutes)

   • After the group discussion, the teacher proposes a moment of individual reflection. He asks two simple questions for students to silently think about for a minute.
   • The first question is: "What did you learn today about sharing and what does it mean to you?"
   • The second question is: "How can you use what you learned today about sharing in your everyday life?"

3. Sharing Reflections (2 - 3 minutes)

   • The teacher invites some students to share their reflections with the class. This can be done voluntarily or through random selection.
   • During this moment, the teacher validates the students' reflections, reinforcing the importance of what was learned and encouraging them to apply this knowledge in their daily lives.

This feedback is essential to consolidate students' learning. The group discussion allows students to learn from each other, while individual reflection promotes self-awareness and critical thinking. Additionally, sharing reflections helps transfer learning from the classroom to students' daily lives.

Conclusion (3 - 5 minutes)

1. Lesson Summary - The teacher should summarize the main points covered during the lesson. He can review the concept of sharing and equal parts, emphasizing that when we divide a whole into equal parts, each part has the same value. Additionally, he can recap the sharing strategies discussed during the practical activities.

2. Connection between Theory and Practice - The teacher should highlight how the lesson connected theory (the concept of sharing) with practice (the sharing activities carried out). He can mention that through the activities, students were able to apply the concept of sharing in everyday situations, thus developing a deeper understanding of the concept.

3. Suggestion of Additional Materials - The teacher can suggest some extra materials for students who wish to deepen their understanding of the subject. This may include children's books that address sharing, interactive online games involving sharing, or educational videos on the topic.

4. Importance of the Subject - Finally, the teacher should emphasize the importance of the subject for students' daily lives. He can mention that sharing is an essential skill for social interaction, as it allows us to share resources fairly. Additionally, he can highlight that the concept of sharing is used in various areas, from mathematics and science to arts and physical education.

This concluding moment is crucial to reinforce the lesson's learning and to encourage students to continue exploring the subject on their own. Furthermore, by connecting theory with practice and emphasizing the importance of the subject, the teacher helps students understand the relevance of what they have learned.
