I would adapt this for play therapy, for sure! Fun, easy, quick and invites child involvement on many levels! This would be a great activity for an indoor recess. The children could make the ring and decide what the game rules are.
Spelling "Leadership" by grade level in the cafeteria. This is an incentive for each grade level to work together to earn a letter by following the rules and procedures. Once they spell leadership, they earn an extra recess.
