Triangles and quadrilaterals card sort

This card sort is designed as a cooperative activity which can be used to develop mathematical vocabulary or as a plenary on the subject.

This resource contains ten shapes (including the broader categories of triangle and quadrilateral), with names, images and descriptions for children to match. These could be given out as a complete sheet for children to cut up, sort and stick into books or pre-cut, laminated and sorted into envelopes for children to be able to sort and re-use them.

Objectives:

• compare and classify geometric shapes, including quadrilateral and triangles based on their properties and sizes.
