Play with empty cans, stacks and flip.
Use cans with rounded edge (hazard of injury!)
Clean them and remove labels.
When the doses have fallen, rebuild.
Can be repeated as often as possible.
Collect several doses in one tub.
Prepare a narrow board on which are painted as help for younger children, circles in diameter of tin cans.
Show the children how the cans could be stacked on the board and then let them try for themselves.
With a ball, the can wall can be thrown over.
Creative development is encouraged.
