Set up an area with a dividing line splitting the area into two. The line can be on the ground or up in the air like a tennis/volleyball net. The class is split into two teams with one team on one side being the "catchers" and the other on the other side being the "throwers". The throwers start with all the items on their side and must throw the items over the division line for the catchers to catch. If an item is caught then it is carried over and placed in a hoop on the side. If an item is dropped then it is thrown back to be tried again. The game finishes when all items are in the hoop.
Change the height of the division line to change difficulty. Adjust the size of the area of play to change difficulty. Change the type of item used for throwing to make the game easier or harder. Create more teams of less people.
