Janken Battle

Put 10 or more cards on the table or on the floor.  The kids line up in teams at either end of the cards.  When you say go, they move along the line saying the words out loud.  When they meet they do "rock, scissors, paper" and the winner stays where they are and the loser goes to the back of their team and the next team member starts from the beginning of the cards.  Continue until a team gets to the opposite end.
