Method: Scouts are scattered throughout the room.
The leader says, "Form fives" (or fours, or threes, or twos).
Scouts have to get into groups of whatever size is announced.
Those who don't get into a group of the correct size are out of the game.
Could be used for large groups at a Camporee.
Or use the next game to call the numbers.
Also when a group is reduced from 5 to 4 and a person is expelled stop and do a reflection, ask the expelled person how they felt and why?
