A game I played with Friends children all so at a after school sceme.

You need 5 toys or sweets (only if child or children parents agee) I used little toys.
Hide them in places before the children come the child or children are allowed to go.
When they come tell them your lost 5 things and need there help in finding them.
Send them off to find the toys or sweets.
See how long it take them.
