Right!
And actually, this happened to me during graduate school, regarding
what it means to multiply one fraction by another fraction. This is a
concept that I never understood until Dr. Evelyn Neufeld walked my
class through doing it with base ten blocks. I was sold.

who

Marilyn Burns and Bill Martin and many, many others have teased out
common
strategies which will help us learn; it's up to us to use them in a
sensible
way. We don't get to leave our brains at the door. Right, Renee?
