Area is a circle or square, some players with a ball and some without. The coach gives instructions on what kind of group to form, and players must follow the instruction. For example, "Four players, two balls!"
The goal is to be able to form groups quickly; each task can also be given a time limit (e.g., 30s).
Make it harder: More complex instructions, e.g., "Group with eight feet and two balls. Two hands on the ground!"
Quality factors
Observation, problem-solving, group formation, speed
Key questions
Was grouping successful, did anyone get left out, was the tempo maintained?
