Crackerball is an individual dodgeball game.  (Every man for himself)  I
use this game for 3rd grade and up.  The players are allowed to use the
entire floor.  When a player gets hit with the ball, or if someone
catches the ball he has thrown,he moves to the baselines or the
sidelines.  The people who are on the baseline and the sideline can throw
the ball and hit the players who are still in to get him OUT.  Therefore
you wind up with one ultimate winner.  If you have players who are
holding the ball too long the teacher says "1,2,3 CRACKERBALL!". If a
player gets caught holding onto the ball when crackerball is called then
that player is OUT.  I let the players tag other players with the ball,
but if the ball is taken away from the player who is trying to tag him
then it is void, and neither one of the players are out.  When the
teacher is counting  "1,2,3 CRACKERBALL"  other players should try and
knock the ball out of the way of the person who is trying to keep
position of it.  It is risky, but in order to keep the game flowing the
teacher sould encourage such action.
