  2. Match to a 3D shape.
  3. Imagine folding.
  4. Check: no overlaps or gaps.

Key words: net, face, edge, vertex, prism, pyramid.

Worked examples

The first three practice questions from the lesson, with every step.

Question 1

Will this net fold to make a cube?

  1. Step 1: Look at the net
  2. Step 2: Imagine folding it up around one square.

Answer: Yes

Question 2

Will this net fold to make a cube?

  1. Step 1: Look at the net
  2. Step 2: Imagine folding it up around one square.

Answer: Yes

Question 3

Will this net fold to make a cube?

  1. Step 1: Look at the net
  2. Step 2: A 2 by 3 block can't fold into a cube - faces overlap.

Answer: No
