Calendar: Great classroom organization tip! Put calendar numbers or words on large rings--everything flips. No more boxes/files to store extra numbers or words. Make a few blank cards on the rings too, so you can change things up when necessary.
MATH Area math game: Roll the dice and draw the area array on your own grid - first to fill it wins. Or 2 players choose a different colored pen each, use one grid and the player who cannot complete the last array is the loser.
