How can you tell they’ve got it: 3-D shapes (age 9+)?

If they’ve got it, you’ll see things like: Identify a cuboid from its net; Name the 3-D shape shown in an isometric drawing; Match 2-D representations to the correct 3-D shape. Or just try it together: If you show your child a flat architect's sketch of a box or a pyramid, can they tell you the name of the 3-D shape it represents?

3-D shapes (age 9+)

Your child can name a solid shape from a flat drawing of it, like telling a box from a pyramid on a plan.

In curriculum terms
