Give each kid three sticks. Each time a kid talks out of turn, take a stick away. Lose all three and talk out of turn again, get a red stick. Each red stick = lose 5 mins of recess (or whatever consequence you choose). Hmm.... Something to consider.
High five notes! Great idea! I will give more specifics to name greatness qualities...what is so great about them?? ex. "When you shared, you were being a kind friend!" or "You were focused on your work today!"
