Shoebox lid & craft sticks- these are wide ones, and low temp glue gun. Endless fun and all you need is a shoe box lid and Popsicle sticks! Build a marble run or "Plinko" with all kinds of different creative designs via Frugal Fun For Boys
You will need thick straws (thin ones work too), small sheets of paper. Using straw players will need to suck the paper sheets and transfer them from one pile to another. Whoever does this first WINS the game.
Numbered Photo Puzzles - why make a mess when you can just use your Xyron machine? Run the photo through the Xyron, flip it over and lay the popsicle sticks on the sticky side, then cut apart (or use an exacto knife if parents are helping)!
