Team Dodgeball is a dodgeball game where you play on teams.  Each team
starts out by throwing from the half court line.  When a player gets hit
or someone catches the ball he has thrown, he is OUT!  Have a designated
area on the side that the players go to, because they are OUT until a new
game begins. Then the teacher blows the whistle and calles the three
point line.  When there are only a few players left in the game the
teacher then calles another line that is closer than the three point
line.  I have the loosing team run one lap and then a new game starts. 
If the teams start out uneven, then the teacher can let the weaker team
go to the three point line and keep the other team at the half court line
until the numbers even up
