I found a small gumball machine at the Dollar Tree. It's not the kind you can put a penny in, but it works! I wrote the numbers 1-100 (not all of them...I left a few out, just so the kids couldn't color all of them and say they were done. Ha!) on glass gems, also purchased at the Dollar Tree. The children color the number on their hundred chart that matches the number that came out of the gumball machine.
