This is a great cooperative activity. The object of this activity is to see how large a rainbow 2 players can make without missing a return catch. Two players begin by standing approximately 6' apart. Player A launches the GrabBall towards player B to start play. If each player is successful in catching the ball, a full rainbow is created and both partners take one giant step backwards as the continue to launch and catch.
Players continue until the rainbow becomes bigger, as long as no misses occur.
If one of the players misses, both players must take one giant step closer to each other. Line player pairs along the gym and watch a number of rainbows develop. Later, have players try tossing 2 GrabBalls at a time. This is a more challenging cooperative activity for students. Three players line up about 10' between each other.
