2-D faces on 3-D shapes

CONCEPTUAL
Mathematics›Geometry|Ages 6—7|ID: mt_UooUHC_V7U

Identify 2-D shapes on the surface of 3-D shapes (e.g. a circle on a cylinder, a triangle on a pyramid)

Mastery Evidence

  • Point out a circular face on a cylinder or cone
  • Identify triangular faces on a pyramid
  • Recognise that the faces of 3-D shapes are 2-D shapes

Assessment Prompt

“Can [child] look at a 3-D shape and name the 2-D shapes on its faces — for example, saying a cylinder has circles on the ends and a rectangle wrapped round the side?”
