Giving children chance to 'play around' with two-dimensional shapes gives them the freedom to explore spatial properties for themselves, thereby developing their understanding in a meaningful way. These activities offer contexts in which children can engage in this 'play'.

Age 5 to 7

Challenge Level

Can you sort these triangles into three different families and explain how you did it?

Age 5 to 7

Challenge Level

Vincent and Tara are making triangles with the class construction set. They have a pile of strips of different lengths. How many different triangles can they make?

Age 5 to 11

Challenge Level

This activity focuses on similarities and differences between shapes.

Age 7 to 11

Challenge Level

How would you move the bands on the pegboard to alter these shapes?

Age 7 to 11

Challenge Level

This practical problem challenges you to make quadrilaterals with a loop of string. You'll need some friends to help!

Age 7 to 14

Challenge Level

This task requires learners to explain and help others, asking and answering questions.

Age 3 to 11

This series of three articles discusses the development of geometric thinking.
