This is a very simple activity in which the group counts to twenty (or higher) with each player saying their number in turn. Each Cub has to listen to the previous numbers being said and only calls out a number once they are certain it is their turn and they are aware what numbers have already been said.  Start by going around the circle clockwise.  Once they get the idea, they need to count based on who you point to.  Hold a few practice rounds.  Hesitation or wrong number means you are out.  You move faster and faster as the game progresses until only one person is left.
