A team version of dodgeball.
Use one or two large/ish (volleyball or football sized) balls. The softer the ball the slower it is and easier to dodge and better for young children. Older children often prefer playing with a faster, harder ball which requires more skill to dodge, such as a cheap football (UK football/soccer).
Divide into two teams. All players mix around the playing area. One team starts as the taggers. A player holding the ball may only take one step only in any direction and has the choice of either trying to tag an opposing team player or throwing to another member of his/her team. Control of throwing the ball changes to the opposing team when any throws to another team member are dropped/missed. Team with most tags wins.
