Why this why now
This unit allows pupils to explore 2-D shapes, composing and constructing shapes in different ways. Pupils are introduced to the concept of parallel and perpendicular sides as properties of shapes. Using different grids, including geoboards, draw triangles and quadrilaterals with given properties. In the unit, pupils have opportunities to rehearse and use the language of 2-shapes and their properties. This unit prepares them for work with other polygons and work on perimeter in the future.
Prior knowledge requirements
- Recall number facts and sequences
- Use place value understanding
- Apply basic operations in context

Parallel and perpendicular sides in polygons
In this unit pupils will investigate ways to compose and decompose polygons. They will investigate quadrilaterals with and without parallel and perpendicular sides.
