Shape capacity

Kids work in pairs. Make a shape that has been built up e.g. the triangle in this picture. Use Mrs Murray’s blocks, lego, duplo etc. Ideas could be rectangles, squares or even try a hexagon with the blocks.

Create two different shapes, or join with another group. Your job is to now work out which shape holds the most amount? 

Materials they could use: unifix, tennis balls, anything in the room that is the same size.
