2 or more carpet squares (remnants)
Lay two pieces of carpet a few inches apart on the floor. With your child, take turns jumping from one carpet square to the other. Keep increasing the distance between the squares. With older children, have them measure the increasing distance between the carpet squares and chart it, along with the jumping results.
This activity provides a wonderful opportunity for imaginative play. You and your child can pretend that the distance between the two carpet squares is a river or any other liquid your child might not want to fall into.
