2-D faces on 3-D shapes

Mathematics · Geometry · conceptual

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

What mastery looks like

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

Check your understanding

Can 2-D faces on 3-D shapes 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?
