Eight children each had a cube made from modelling clay. They cut them into four pieces which were all exactly the same shape and size. Whose pieces are the same? Can you decide who made each set?

Here are shadows of some 3D shapes. What shapes could have made them?

Can you split each of the shapes below in half so that the two parts are exactly the same?

What does the overlap of these two shapes look like? Try picturing it in your head and then use some cut-out shapes to test your prediction.

How many balls of modelling clay and how many straws does it take to make these skeleton shapes?

A hundred square has been printed on both sides of a piece of paper. What is on the back of 100? 58? 23? 19?

I've made some cubes and some cubes with holes in. This challenge invites you to explore the difference in the number of small cubes I've used. Can you see any patterns?

An activity centred around observations of dots and how we visualise number arrangement patterns.

A task which depends on members of the group working collaboratively to reach a single goal.

Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a square.
