Work with your children to create an indoor obstacle course. You might include crawling under a table, jumping over something, somersaulting over pillows, climbing stairs, rolling sideways through the room, or dodging around chairs. After all players follow you around the obstacle course, time each player to see how long it takes them to get through the course - record their time on a piece of paper. After each player has tried the course, let everyone play again to see if they can better their time. If they enjoy playing, challenge the children to create their own obstacle course for their friends to try.
This activity builds the Developmental Assets of Commitment to Learning, Empowerment, Positive Identity, Positive Values, and Constructive Use of Time.
