AWESOME IDEA! Gallon Ziploc bags + Fancy Duck tape = An art quilt! Artwork slides in the back. You won't see where it says Ziploc because that is on the back side! Displays kids' artwork throughout the year.
Math tub idea: Get two ice trays from the dollar spot at Target, write 2-digit numbers on white labels for each hole, and kids toss a cube in each tray and add numbers together on recording sheet or whiteboard.
