KS1 & KS2 maths curriculum

This unit revisits the properties of 2D and 3D shapes and ideas of area and perimeter. Pupils use their knowledge and understanding to reason about shapes including 2D nets of 3D shapes and the relationship between side lengths and both area and perimeter. They revisit the idea that shapes with the same area can have a different perimeter and vice versa. This prepares them for calculating the are and perimeter of other shapes in the future.

1. Use knowledge of shape properties to sketch and identify shapes
2. Use knowledge of shape properties to draw shapes accurately using rulers and protractors
3. 3D shapes can be composed from 2D nets
4. The same 3D shapes can be composed from different 2D nets
5. When a 2D shape is decomposed and the parts rearranged, the areas remains the same
6. Any parallelogram can be decomposed and the parts rearranged to form a rectangular parallelogram
7. Two congruent triangles can be arranged to compose a parallelogram
8. Shapes with the same areas can have different perimeters and vice versa
9. Reason about shapes using the relationship between side lengths and area and perimeter
10. Reason about compound shapes using the relationship between side lengths and area and perimeter
