In our kids' 5th grade class (EM) they were never taught how to simplify fraction-multiplication problems by factoring across the two fractions (our kids already knew how before the year began.)

I love how SM assumes you know how to do that.

Auntie Ann, damn straight. I've had to teach fraction "canceling" to several kids now. Thanks for the reminder; I should work with my after-school tutees on this ...
