NOTE 2: We originally began using only whole numbers as a starting point, but students then wanted to branch out further. Could we extend this question to include integers?!
I say no-way but ask him to tell me more after class. If he's right, I promise him an extra five points on the next quiz. Slide and Divide always works. So how does it work, why does it work, and what made it stop working. We begin with an easy example:.
