RE: Who are we?
Yes, this arithmetic was awful and "see" and "say" was ridiculous although I managed to miss it and I think it's gone from our system now. Some teaches just refused to teach it. I also have a pet peeve about elementary school math being taught by arts graduates that never liked math.
When I first heard the phrase "common core" I thought it had something to do with common curriculums between states. We had done something similar between school boards in Ontario just because people are mobile, and when you move from one area to another, the systems shouldn't be completely different.
As long as a student has an internet connection, they can learn for free from the Khan Academy and they will learn properly but they still won't pass that test.
I have a friend whose son flunked a question on a physics test because he knew too much for his schooling level. I disagreed with that too.
