Introduction

Duration: 10 to 15 minutes

The purpose of this stage of the lesson plan is to introduce students to the concept of volume of rectangular prisms, ensuring they understand the importance and practical application of this knowledge. By defining the main objectives, the intention is to provide a clear and focused overview of what will be learned, establishing a solid foundation for the development of the skills necessary to calculate volumes and solve related problems.

Context

Start the lesson by explaining to students that volume is a measure that determines the amount of space occupied by an object. Use everyday examples to make the concept more tangible. For instance, show a shoebox and ask the students how much space is inside it. Explain that this 'space' can be measured and is what we call volume. Use a larger and a smaller box to illustrate that although the shape is the same, the volume is different.

Curiosities

Did you know that the concept of volume is widely used in various professions? For example, architects and engineers need to calculate the volume of spaces to determine how much material will be needed for a construction. Additionally, in our day-to-day lives, when we buy a bottle of soda, we are dealing with volume, as the liquid occupies a certain space within the bottle. Even when cooking, when we measure ingredients, we are dealing with the volume of liquids or solids!

Development

Duration: 40 to 50 minutes

The purpose of this stage of the lesson plan is to deepen students' knowledge about calculating the volume of rectangular blocks, providing them with a clear and practical understanding of this concept's application. By addressing specific topics, solving problems, and discussing practical examples, students will be able to apply the volume formula in real situations, consolidating their understanding and mathematical skills.

Covered Topics

1. Definition of Volume: Explain that volume is the amount of space occupied by a three-dimensional object. In particular, for a rectangular block, the volume can be calculated by multiplying the length, width, and height of the block. 2. Formula to Calculate Volume of Rectangular Blocks: Show the formula V = Length x Width x Height. Detail each component of the formula, explaining that 'V' represents volume, 'Length' is the measure of the base, 'Width' is the measure of depth, and 'Height' is the measure of the height of the block. 3. Practical Examples: Present practical examples and solve them on the whiteboard. For example, calculate the volume of a shoebox with 30 cm of length, 20 cm of width, and 10 cm of height. Solve the problem step by step, showing the multiplication of the measurements. 4. Conversion of Units: Discuss the importance of using consistent units when calculating volume. Explain how to convert between different units of measurement, such as cubic centimeters to cubic meters. 5. Applications of Volume Calculation: Highlight how volume calculation is used in various everyday situations and professions. For example, how engineers calculate the volume of concrete needed to build a foundation.

Classroom Questions

1. Calculate the volume of a rectangular block with 12 cm of length, 7 cm of width, and 5 cm of height. 2. A box has 50 cm of length, 30 cm of width, and 20 cm of height. What is the volume of this box? 3. If a bottle has the shape of a rectangular block with 10 cm of length, 5 cm of width, and 25 cm of height, what is the volume of the bottle?

Questions Discussion

Duration: 20 to 25 minutes

The purpose of this stage of the lesson plan is to review and reinforce students' understanding of calculating the volume of rectangular blocks. By discussing the answers to the presented questions and engaging students in additional reflections, it will be possible to consolidate learning, clarify doubts, and promote a deeper and more applied understanding of the concept of volume.

Discussion

• 📝 Discussion of Resolved Questions:

• Question 1: Calculate the volume of a rectangular block with 12 cm of length, 7 cm of width, and 5 cm of height.

• Explanation: Use the formula V = Length x Width x Height.

• Length = 12 cm

• Width = 7 cm

• Height = 5 cm

• Calculation: V = 12 cm x 7 cm x 5 cm = 420 cm³

• Question 2: A box has 50 cm of length, 30 cm of width, and 20 cm of height. What is the volume of this box?

• Explanation: Use the formula V = Length x Width x Height.

• Length = 50 cm

• Width = 30 cm

• Height = 20 cm

• Calculation: V = 50 cm x 30 cm x 20 cm = 30,000 cm³

• Question 3: If a bottle has the shape of a rectangular block with 10 cm of length, 5 cm of width, and 25 cm of height, what is the volume of the bottle?

• Explanation: Use the formula V = Length x Width x Height.

• Length = 10 cm

• Width = 5 cm

• Height = 25 cm

• Calculation: V = 10 cm x 5 cm x 25 cm = 1,250 cm³
