day of school. love this idea! You can put students in groups and have them come up w/ a structure w/ 100 cups. Would be interesting to see what they come up with! *I can't get the song "Red Solo Cup" out of my head after seeing this pin!
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 coloured pen each, use one grid and the player who cannot complete the last array is the loser.
