1.1 Solids and Nets

This lesson

This lesson is about Solids

Learning objectives

I can recognise a cube, cuboid, prism, pyramid, cylinder and cone.

What shapes do you recognise?

All solids!

Solids

A solid is a 3D shape

Do you recognise these shapes?

Drag the name to the right shape. 

Pyramid

cylinder

cone

Cube

Sphere

Prism

Cuboid

Faces

Every solid has faces.

There are two kinds of faces

• flat faces
• curved faces

drag the solids to the right box. 

Only flat faces

only curved faces

flat and curved faces

Vertex and edge

Solids with flat faces have:

• faces
• edges
• faces

Vertex, edge and face

• Vertices are named with a capital letter.
• An edge connects 2 vertices and is named with the letters of the vertices (alfabetical order)
• The edges form a face
• The face is named by the vertices of the faces: start in left bottom corner and then anti-clockwise. 

dotted line: the edge can not be seen from you standpoint 

flat and curved faces

a cylinder has two flat faces and one curved face.
