Then you can play all the games you did as a child, "Duck, Duck, Goose." You form a circle and one or two players go around the circle tapping the children and you lightly on the head saying, "Duck". When they say "Goose" that person has to jump up and chase them clockwise around the circle until one of them is able to get back to the space left by the goose and sit down. If the goose tags the duck, then the duck is still it.
Tag. Freeze tag. Musical freeze tag.
