2D and 3D objects: sides, vertices and symmetry

This guide provides a sequence of small steps for exploring shape, from recognising 2D shapes and 3D objects through to making patterns with shapes and objects. Note in this resource objects are often referred to as 3D shapes. It is advised to use the terminology 'objects' when talking about 3D and not 3D shapes as suggested in this resources.
