This 14-sided big foam dice is SO MUCH FUN!  Each side of the dice has a different variation to play.  Every few rounds, have a player roll the dice, and whatever variation is facing up when the dice stops is the rule for the next few rounds of play!  It could be no jumping, catch and toss, no spiking, weak hand only, etc.!  This really simple tool mixes up the game play to engage students even more!
