Discuss and compare 3D shapes

Maths

Recognise and sort polygons

Describe and name polygons, including triangles and quadrilaterals

Describe, name and sort polygons, including pentagons, hexagons and octagons

Lines of symmetry

Discuss and compare polygons

Investigate how polygons can be joined and folded to form 3D shapes

Describe and name 3D shapes

Describe and name 3d shapes – prisms and pyramids

Find different ways to sort 3D shapes

In this unit pupils will learn that polygons can be described, sorted, compared and named according to the number of sides and vertices. They will describe 3D shapes finding different ways to sort and compare them. In the future unit pupils will investigate different ways to compose and decompose a polygon. They will investigate quadrilaterals with and without parallel and perpendicular sides. 

In the prior unit pupils composed, copied, extended and developed repeating and radiating patterns. They explored, discussed, and compared 3D and 2D shapes. In this unit pupils will learn that polygons can be described, sorted, compared and named according to the number of sides and vertices. They will describe 3D shapes, finding different ways to sort and compare them.
