Maths

Make shapes by joining two polygons in different ways

Investigate different ways of decomposing a polygon

Draw polygons on isometric paper

Construct quadrilaterals with and without parallel and perpendicular sides

Identifying parallel lines

Make and draw triangles on circular geoboards

Make and draw quadrilaterals on circular geoboards

Draw shapes with given properties

Draw shapes with given properties on a range of geometric grids

In this unit pupils will investigate ways to compose and decompose polygons. They will investigate quadrilaterals with and without parallel and perpendicular sides. In the future unit pupil will learn perimeter as the distance around the edge of a 2D shape. They will learn perimeter is measured in units of length found by counting units and by calculating by adding the side lengths of a 2D shape.

In the prior unit pupils rotated two lines around a fixed point to make different sized angles. They identified vertices. In this unit pupils will investigate ways to compose and decompose polygons. They will investigate quadrilaterals with and without parallel and perpendicular sides.

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

Parallel and perpendicular sides in polygons
