Mark out an area to play the game and explain the boundaries of the game to the group.
Choose two ‘catchers’ who stand on either side of the marked area and work together to try and roll the ball and hit people below the knee.
Anyone who is hit with the ball then joins the ‘catchers’ to again work together to catch others.
A tip to make sure that you don’t always have the same people left at the end is to play the game until there are two left and they then they become the ‘catchers’ for the next round.
