My husband is a PhD candidate @Harvard SEAS and he sent this to me after years of joking that as the kids started to learn math he would teach me as well, starting over with basic arithmetic. This NYTimes contributor beat him to the punch. He is two blog entries in to teaching math. The exercises and resources mentioned would be invaluable to homeschoolers, I think!
I am already learning a lot. For the first time odd number addition equaling perfect squares makes sense!
