Hey, all, I'm just back from a week in Wyoming. It is beautiful there! I'm catching up on some of these posts and am wondering what Modular Arithmetic is? Curious, could you write out an example of what you mean by "long division algorithm as a computational thinking exercise"?

By the way, I'm feeling pretty good about the decision to go with the private school. Now to just sort out some details and scheduling issues (and money, of course!).
