📐 Part 1: Understanding Nets

1. What is a net? Circle the best definition:

A 3D shape with flat faces

A 2D pattern that folds to make a 3D shape

A tool for catching fish

The outside surface of a prism

2. Which of these are prisms? Check all that apply:

Rectangular prism (cuboid)

Triangular prism

Sphere

Pentagonal prism

Cone

3. Fill in the blanks about prisms:

A prism has two __________ faces that are the same shape and size. These are connected by __________ faces. The edges where faces meet are called __________.

🔍 Part 2: Analysing Prism Faces

4. Complete the table about prism faces:

Rectangular Prism: _____ rectangular faces, _____ total faces

Triangular Prism: _____ triangular faces, _____ rectangular faces, _____ total faces

Hexagonal Prism: _____ hexagonal faces, _____ rectangular faces, _____ total faces

5. Match each prism with the correct number of faces:

1. Triangular Prism

2. Rectangular Prism

3. Pentagonal Prism

4. Octagonal Prism

A. 6 faces

B. 5 faces

C. 7 faces

D. 10 faces

✏️ Part 3: Drawing Nets

6. Draw a net for a rectangular prism (cuboid) with dimensions 4cm × 3cm × 2cm. Use the grid below and label each face with its dimensions:

7. Draw a net for a triangular prism. The triangular faces should be right-angled triangles:

8. Explain how you know your net will fold correctly into a prism:

🔧 Part 4: Net Construction Planning

9. Before cutting and folding your net, what should you check? Check all that apply:

All faces are the correct shape

Measurements are accurate

Faces are connected properly

You have the right number of faces

The net uses bright colours

10. List three real-world examples where nets are used in packaging or design:

11. What mathematical vocabulary have you learned about nets and prisms? Write at least 5 terms and their meanings:

🎯 Part 5: Problem Solving

12. A company needs to design a box (rectangular prism) that holds exactly 24 cubic centimetres. If the base is 4cm × 3cm, what height should the box be?

13. Challenge: Can you draw a different net for the same rectangular prism from question 6? Explain why multiple nets are possible for the same prism:

14. Reflection: What was the most challenging part about working with nets today, and how did you overcome it?
