This is a great game that kids love. It is a good warm-up to start the class with. The game can be played with two or more players.
To keep it simple we’ll introduce it as having two players on the court…
One player on each side of the net. One of them starts the point with a “drop and hit”.
Once the ball goes over the net, and bounces in the court, the player has to run to the ball and keep it bouncing with their racquet by either tapping it up or down (players are not allowed to catch the ball by hand). At any moment they could hit the ball back over the net. Once they hit the ball back, that player must then keep the ball bouncing in the same manner and hit it back as soon as he is ready.
The first bounce of the ball, once it goes over the net, has to be inside the lines.
Score: The other player receives a point when a player rolls the ball.
The goal is to keep the ball bouncing and avoid rolling it on their respective side of the court.
Once a point is played (the ball rolled), the player on whose side the ball rolled will start the next point with another “drop and hit”.

Note: The game promotes good racquet control, footwork, and tracking the ball and, if played many times, eventually the kids will start rallying by hitting the ball over the net after one bounce.
