Teams of 4 try and throw the ball across a pitch as quickly as possible, not missing any players out.
The first team to throw the ball 10 times across the pitch is the winner.
Ensure players catch the ball safely, using both hands, before they turn to throw the ball on to the next player.
You can introduce a rule that going one way across the pitch players must throw underarm but in the other direction they must throw overarm.
This will check they're paying attention and also test both their throwing techniques.
