Plus one volleyball begins like a regular game of volleyball. The receiving team must play the ball twice on their side before returning it over the net. Now the serving team must play the ball three times before returning it over the net. Now the receiving team passes it at least four times. Play continues in this fashion with each side passing it amonst themselves one more time than the last. In this game, only the serving team is allowed to score a point. This is a great activity to really focus on controlled passing and on not just trying to get the ball over the net to score a point.
