Sing the polygon rules
Play the Polygon Song, then hold up shapes and ask "Polygon or not?" A circle? No, it's curved. A triangle? Yes, closed with straight sides. The song gives kids the rule, and the quick checks make them use it.
Why it works: words set to a repeating melody are easier to recall than the same words spoken (Wallace, 1994).
