Introduction

Duration: 10 - 15 minutes

This stage aims to introduce students to the concept of volume in a contextualized manner, sparking their interest through practical examples and curiosities. By relating the theme to real-life situations and the job market, students can perceive the relevance of the content they will learn and feel more motivated to participate in the proposed activities.

Contextualization

Volume calculation is essential in various situations in our daily lives, such as when we need to fill a swimming pool with water, package products, or even construct houses and buildings. Understanding how to measure the volume of solid objects allows us to do this more efficiently and accurately, ensuring that resources are used appropriately.

Curiosities and Market Connection

Did you know that the concept of volume is widely used in civil construction to calculate the amount of necessary materials, such as concrete and bricks? In interior design, calculating the volume of furniture and spaces helps optimize the use of available space. Additionally, engineers use volume calculations to design structures and ensure they are safe and functional.

Initial Activity

Propose the following provoking question to the students: 'How many 1 cm³ cubes would fit inside a shoebox?' Then, show a short video (2 - 3 minutes) that explains the concept of volume and demonstrates practical applications, such as building a swimming pool or packing products in a factory.

Development

Duration: 60 - 65 minutes

This stage aims to consolidate the students' understanding of volume calculation of rectangular prisms through practical activities and fixation exercises. The construction of the rectangular prism provides a hands-on experience, while problem-solving promotes the application of theoretical knowledge in practical situations.

Covered Topics

1. Definition of volume
2. Volume of a rectangular prism
3. Volume calculation using unit cubes
4. Practical applications of volume calculation

Reflections on the Theme

Guide students to reflect on the importance of understanding the volume of objects in everyday life. Ask them how knowledge about volume can be useful in their lives and in different professions. Encourage them to think of practical examples, such as product packaging, civil construction, and interior design.

Mini Challenge

Maker Challenge: Building a Rectangular Prism

Students will be divided into groups and given materials such as building blocks (e.g., LEGO), cardboard boxes, or wooden cubes to build a rectangular prism. The challenge is to calculate the volume of the constructed prism using unit cubes.

Instructions

1. Divide the class into groups of 4 to 5 students.
2. Distribute the building materials to each group.
3. Explain that each group must build a rectangular prism using the provided materials.
4. After construction, each group must calculate the volume of the prism by counting how many unit cubes fit inside the structure.
5. Groups should record their calculations and present the results to the class.

Objective: Develop practical building and volume calculation skills, promoting group collaboration and the application of learned concepts in a practical activity.

Duration: 35 - 40 minutes

Evaluation Exercises

1. Calculate the volume of a rectangular prism with dimensions 5 cm x 3 cm x 2 cm.
2. A water tank is shaped like a rectangular prism with dimensions 10 m x 4 m x 2 m. What is the volume of water it can hold?
3. If a box has a volume of 60 cm³ and its dimensions are 5 cm x 3 cm, what is the height of the box?
4. Draw a rectangular prism with dimensions of your choice and calculate its volume.

Conclusion
