After starting the ice cubes melting, we made rainbow crayons. I've seen this idea in quite a few places lately but can't recall where. Grandma Judy gave us a box of old crayons and we peeled the paper off, broke them into pieces and then mixed them in a cupcake pan. Fun!
For a bit of math practice the girls did some Hundred Board Puzzles and then we did a bit of graphing using the cupcake die and graphing sheet from 2TeachingMommies
