Two teams compete against each other across the court. Depending on class size the amount of "gatorskin" balls you might want to use. For a class of 60 students maybe 15 balls. The Objective of the game is to throw the gatorskin balls at the ball that hangs from the bag on the rope. I put clothes pins on the rope on each side. When the slider touches the clothes pin that teams scores a point. Dont forget to slide it back yo the middle after each score.
