Before the activity, create two squares using cones -- one 30'x30' square and, outside of it, a larger 50'x50' square. Explain the activity to students, letting them know you will be focusing on how well they are throwing during the activity. Once you are done with the explanation, place the cage ball in the center of the small square. Divide students into four groups; each group stands evenly spaced along one side of the 50' square.

The interior of the large square is known as the "Danger Zone"; players are not permitted to enter this zone. Also, let students know that all play must cease when the teachers STOP signal is given.

Give four balls to four students on each side of the square. At your signal, players overhand throw balls at the earthball and make it roll across another side of the square, all while keeping the ball from rolling across their own line. If the earthball crosses over a side of the square, the ball is placed in the middle of the square and play begins again.

Balls outside the "Danger Zone" may be picked up and used by any team. Also, balls may only be thrown, and the earthball cannot be touched with the body.
