Can't remember if I've told y'all about the very cool Math training I went through last year. Very intense. I learned a lot. I spent at least 3 hours a month all year learning about 2nd grade math. Best part: the class was split into 2 equal shares - mathematical thinking and fostering math talk. For real, it has changed me, as both a teacher and a mathematician. Example: I now always calculate tip in my head. (Really and truly, I was one of those folks who used the tip calculator on my phone... Not proud of it, just sayin.') Another example, I never ever tell kiddos they "can't" take a larger number away from a smaller number. Everyone know why? Because a few years later, they'll be expected to learn about negative numbers!! We'll be discouraging their mathematical thinking before it even begins. Now I say, "If you subtract a larger number from a smaller number, you'll have to work with a negative number, and you won't...
