Grade 1 · Unit 6: Shape

3D shapes

Solid shapes can roll, stack or slide.

Solid shapes

A football, a box and a tin are solid. They are 3D shapes. You can hold them in your hands.

Naming 3D shapes

A cube is like a dice. A sphere is like a ball. A cylinder is like a tin. A cone is like an ice-cream cone.

Faces

A flat surface on a 3D shape is a face. A cube has 6 faces. They are all squares. A cylinder has 2 flat faces that are circles, and one curved surface.

Roll, stack or slide?

Shapes with curved surfaces can roll. Shapes with flat faces can stack and slide. A cylinder can roll AND stack!

Flat faces of solids

Draw round a cube: you get a square. Draw round the end of a cylinder: you get a circle. A pyramid has triangle faces. You can build 3D shapes with clay and sticks.

What I learnt

• I can name cubes, cuboids, spheres, cylinders and cones.
• I can say which shapes roll and which stack.
