Sorting and classifying 3D shapes

Children's understanding of the properties of shapes is developed from being able to recognise differences and similarities between shapes. Matching activities such as deciding whether a shape will fit in a space of a given shape or into a construction are an initial step along this road.

This can be further developed through sorting activities. Such sorting activities then lead towards the development of an understanding of different classifications of shapes. Sorting and classifying tasks can be set using junk 3D shapes (i.e. 'real world' shapes) or sets of 3D shapes designed specifically for mathematics such as Poleidoblocs.
