Contextualization

Introduction

Sharing, or dividing equally, is a fundamental concept in Mathematics that aims to distribute a number or a set of things equitably. That is, each participant or group should receive an equal amount. This principle relates to the concept of division, one of the four major pillars of Mathematics (addition, subtraction, multiplication, and division).

Although the concept of sharing may seem simple, in practice, it becomes an important skill that requires practice and understanding. Knowing how to share objects fairly is a useful skill for solving everyday problems and also preparing for more advanced studies in mathematics.

It is important to understand that sharing is not just about numbers, but also about equity and justice. When we share something equally, we are practicing the idea that each person is entitled to an equal share. It is more than mathematics; it is a matter of social justice.

The importance of sharing in the real world

The skill of sharing is very relevant in our daily lives, whether in sharing household tasks, distributing resources in a work team, or even dividing profits of a company among shareholders. Furthermore, the concept of sharing is the basis for understanding fractions and for performing calculations related to percentages, areas, volumes, etc.

Another example of applying the concept of sharing in the real world is in gastronomy. When preparing a recipe, it is common to need to divide ingredients equally for the recipe to turn out well. Additionally, when serving a dessert, such as a cake, for example, it is necessary to divide it into equal parts for all guests.

Practical Activity - "Cake Sharing Party"

Project Objective

To familiarize students with the concept of sharing, or dividing equally, through a playful and collaborative practical activity.

Detailed Project Description

Students will be divided into groups of 3 to 5 people. Each group will receive a "cake" (it can be a flat figure of a cake or a three-dimensional object like a sponge in the shape of a cake) and the task will be to divide the cake into equal parts, based on the number of members in each group.

It is important to emphasize that this activity does not involve the use of real food to avoid waste and ensure the safety of the students. The idea is to focus on dividing equally and not on the making or consumption of the cake itself.

Required Materials

1. A cake figure (paper, sponge, EVA, etc.) for each group.
2. Pencils and ruler to make markings on the "cake".
3. Blunt scissors to "cut" the cake.
4. Paper and pen for notes.

Detailed Step-by-Step

1. Divide the class into groups of 3 to 5 students.
2. Provide each group with a cake figure and the necessary materials.
3. Explain the activity: each group will have to divide the cake into equal parts, based on the number of members in their group. For example, if the group has 4 students, they must divide the cake into 4 equal parts.
4. The students should make markings on the "cake" with the pencil, decide how to cut it, and then make the "cut" using the scissors.
5. In the end, each group must present their cake divided into equal parts and explain how they arrived at the result.

Project Deliverables

1. The cake divided into equal parts.
2. A written report of the project by the group containing four main topics: Introduction, Development, Conclusions, and Bibliography used.

In the Introduction, students should contextualize the theme of sharing, its relevance in the real world, and the objective of this project.

In the Development, the group should explain the theory of sharing and division, detail the activity they carried out, the methodology used, and finally present and discuss the results obtained.

The Conclusions should summarize the main points of the project, explain the learnings obtained, and draw conclusions about the project.

The Bibliography should contain references to the resources used in the project, such as textbooks, websites, videos, etc.

Furthermore, teachers should emphasize the development of socio-emotional skills such as time management, communication, problem-solving, creative thinking, and proactivity.
