So what you're saying is that an individual teacher, dept. head, or possibly the administration/board, in your district has decided that they will only allow students to do math in a certain way? I remember my dad teaching me a certain way to do math problems 30 years ago and having to learn another way in school because that wasn't how the teacher wanted it done. CC does not dictate that students will do a math problem in only one way or that other ways are wrong. It encourages students to look at multiple angles of approach to solving problems. It's far from a perfect system, and I'm not here to say that it doesn't have it's share of problems, but the rabid opposition to it seems more partisan than reality driven.
