The game takes place in a court area, with half of the class at one end, and the remainder inside the court fielding. You need 1 tennis ball, but can use bat or tennis racket.

The hitting team take it in turns to hit the ball and run up to end of court and return if it is safe to do so without getting caught. The hitting team receives one home run when the child has run up to the end line and back. Children can stay on end line if they like and come back when safe. However, you can only have a maximum of 5 children on the end line; when there's 5 on the end line ALL of them must run back!

Children go out by being caught out or being touched by a fielder who has the ball in the contact hand.

The fielding team can pass the ball in front of the child who is running, on the way to the end line. Once on the end line, the runner can stay or come straight back.

When three children are out, everyone is out and the hitting / fielding teams swap over.
