We need your "Ensure", Gatorade and milk caps!

My math students and I need caps for math activities. The Ensure caps have a metal piece that help to teach all sorts of math things, from prime factorization to finding LCD of rational expressions in algebra. You don't need to take out the metal piece... I'm getting pretty good at that. ;-)  The Gatorade and milk caps come in different colors and hold magnets well for board lessons.

When you have some caps saved up, please drop them off at my office, I can pick them up (colleagues and students) or I will provide an address if you need one.

Our math students and I thank you! I will soon post a little lesson on how to use the caps to find the GCF and LCM of a pair of numbers. Later on I will post a lesson on finding LCD of rational expressions. Fun, huh? Thank you so much for your help!
