Find a partner with blue eyes. Find a partner with pigtails. Find a partner wearing a green shirt or whatever way you choose for the players to find partners. Have each team grab a 12-inch beach ball. Each team finds a place on the court away from the others or an area that you designate. Both players practice hitting forehand and backhand groundstokes to each other with the beach ball. The students love to play this game. I introduce beach ball groundstrokes only after I have taught the children alternating groundstrokes. They learn how to get their bodies turned and follow through more quickly than with any other game I know.
