The circle have a ball which is thrown from the Brownie in the centre to one on the outside and back again. Each time it is thrown and caught by both girls a point is scored - keep going round the circle counting but start at one again if the ball is dropped.
Meanwhile, the other group run around the circle one at a time until all the Brownies have had a go (pass a beanbag as a baton) and they shout stop when the last one returns to the back of the queue.
Swap the groups over and see which group scores the most points with the ball.
