For this game you will need some balloons!
Each child has a balloon and upon instruction they throw the balloon into the air and catch the balloon on the part of the body shouted out by the coach, e.g. head, knee, tummy, etc.
Progress this to children patting the balloon around the grid, when the coach shouts a body part they need to grab their balloon and balance it on that body part. The last child to do so loses a life (everyone starts with 10). The winner is the child/children with the most lives left at the end.
