## Stacking Cups – Two Stacks

This is a 3-Act lesson. It involves systems of linear equations to model a physical situation. (This could be thought of an extension of the cup-stacking activity that has been around for some time. However, I think this lesson can be done without the original, one-stack lesson.) http://www.101qs.com/1897-stacking-cups–act-1#
