two small balls
Have children line up. Mark off a start line, and a finish line. You can use masking tape, or a rope. Place a small ball between the first child?s knees. When you say ?Start!? have the first child walk to the finish line and back while keeping the ball between his knees. If he drops the ball, have him pick it up and keep going. When he gets back to the start, have him pass the ball to the next child. Do the same thing till all the kids have gone through. If you have lots of children, you can have two teams and make it a race!
