3-D shapes
Recognise and name common 3-D shapes (cubes, cuboids, pyramids, spheres, cylinders, cones)
What a learner can do afterwards
- Name a cube, sphere, cylinder, and cone when shown them
- Identify 3-D shapes in the environment (e.g. a tin is a cylinder)
- Recognise a cuboid and a pyramid among a set of solid shapes
The lesson
A 3-D shape is not flat. You can hold it and turn it around. It has sides, corners, or curves you can touch.
A dice is a cube. It has six flat, square sides that look the same. A ball is a sphere. It is round all over, with no corners at all.
There are six 3-D shapes to know. They are cube, cuboid, pyramid, sphere, cylinder, and cone. A cuboid looks like a cube, but longer. Think of a cereal box or a shoe box. A pyramid has a flat bottom. It comes to one point at the top.
Try the roll test. A ball and a tin can roll easily. A box cannot roll, because it has flat sides and corners. A cone can roll in a curvy circle.
Six shapes to spot: cube, cuboid, pyramid, sphere, cylinder, and cone.
