Not much that's good. As a math teacher- I had to "unteach" about 9 years of fractions and common core taught wrong by elementary school teachers. so frustrating. I brought in a bunch of change (this was an algebra class), and we played customer and cashier one day. taught them how to count back change correctly without a calculator. crazy what they don't know these days. On the other hand, that also means the new generation won't be coming for our jobs any time soon, now don't it?
