Head and catch

Stolen from: A Network for Jewish Youth

Players stand in a circle with a leader in the middle. The leader throws the ball towards a young person and says either "catch" or "head." If the leader says "catch" they have to head the ball and if the leader says "head" they have to catch the ball. If anybody does it wrong they're out.

If you want to make it more difficult, tell the players to run round the circle after every go; it breaks their concentration.
