This activity investigates how you might make squares and pentominoes from Polydron.
Make a cube out of straws and have a go at this practical challenge.
How can you put five cereal packets together to make different shapes if you must put them face-to-face?
Erick (Sciennes Primary School, Edinburgh) sent in this solution:
This collection of solutions from Moorfield Junior School shows how the layers can be placed in different orders, or the whole cube turned upside-down, or described from different angles.
Kelly and Josephine showed their solution in another, rather clever way. They used letters, but we have used coloured squares to help you see how this net would show all the little cubes when it was folded into a cube.
