Players walk around the room. The facilitator calls 'Stop!' followed by three numbers. The first number indicates how many players must form a group. The second number is how many hands the group must have touching the floor. The third is how many feet.
For example: '4 - 2 - 3' means groups of four with two hands and three feet on the ground. The group must figure out how to arrange themselves to meet the requirement.
This is a physical, creative problem-solving warm-up that gets everyone laughing.
