**3-D shapes - third and fourth class **

Content for third class

*The child should be enabled to*

- Identify, describe and classify 3-D shapes, including, cube, cuboid, cylinder, cone, sphere, triangular prism and pyramid?
- Explore, describe and compare the properties of 3-D shapes e.g. such things as
*number and shape of faces, number of edges and corners, ability to roll, slide or stack?* - Explore and describe the relationship of 3-D shapes with constituent 2-D shapes?

*Identify constituent 2-D shapes by observation and deconstruction and compile a table of results.* - Construct 3-D shapes.

*Trace around nets and cut out. Use straws or pipe cleaners*to create constructions. - Solve and complete practical tasks and problems involving 2-D and 3-D shapes.

Content for fourth class

*The child should be enabled to*

- Identify, describe and classify 3-D shapes, including cube, cuboid, cylinder, cone, sphere, triangular prism and pyramid?
- Establish and appreciate that when prisms are sliced through (in the same direction) each face is equal in shape and size.

*Keep work exploratory and simple e.g. use Plasticine, triangular prisms or suitable foods.* - Explore and describe the relationship of 3-D shapes with constituent 2-D shapes
- Construct 3-D shapes e.g.
*construct from 2-D shapes* - Solve and complete practical tasks and problems involving 2-D and 3-D shapes?

*Identify the use of 3-D shapes in the environment.*
