What we are learning

Sort 2D and 3D shapes by their properties.

You will need: Pencil, 3D shape models or boxes and tins, Feely bag

Warm-up

Feely bag: reach in, describe a 3D shape without naming it, and let others guess.

12D or 3D?

Write 2D or 3D next to each shape.

2D or 3D?
cube
circle
sphere
triangle
cylinder
square
pyramid
rectangle

2Faces, edges, vertices

Use the models to count each one.

cube
cuboid

cone
square-based pyramid

3Match the object

Join each 3D shape to a real object.

  • sphere
  • cube
  • cylinder
  • cone
  • cuboid
  • a tin of beans
  • a party hat
  • a dice
  • a football
  • a cereal box

4Roll, stack, slide

Test each shape and tick what it can do.

cube

cylinder

cone

5Shapes inside shapes

Which 2D shapes can you see on the faces of each 3D shape?

  1. 1. cube →
  2. 2. cuboid →
  3. 3. cylinder →
  4. 4. square-based pyramid →

6Practise again

Read the clue and name the 3D shape.

  1. 1. 6 square faces
  2. 2. 2 circle faces and 1 curved face
  3. 3. 1 circle face and a point
  4. 4. 6 rectangle faces
  • I held the model while I answered.
  • I used the words face, edge and vertex.

7My sorting rule

Sort your shapes into two groups. Write your rule and which shapes went where.

8Take it home

Find three 3D shapes in your kitchen. Write the object and the shape name.

⭐ Challenge

Which 3D shape rolls AND stacks? Explain why using the words face and curved.

How did I do?

  • I can tell 2D from 3D.
  • I can count faces and edges.
  • I can make my own sorting rule.
  • I can name the 2D faces on a 3D shape.
