I'm confused about "Common Core". Are we for it or against it?

10. As I understand it part of the problem is that the implementation is very vague.

Basically common core sets up a national scope and sequence, so ideally second graders should all be learning single digit multiplication and state history and reading from a set list of relatively easy chapter books. Which is great to the extent that if your family moves you kid probably should be doing something similar at her new school to her old one, and all third grade classes should be able to start in the same place.

But the problem is that there's really no explanation for what to do when things aren't ideal. If you've got two kids in that class who are behind on their math and three who don't read all that well and one who is an English learner who can't read in English at all, plus three kids who are gifted and bored to tears by the work at their supposed grade level, what do you do with all of them? As I understand it there's really no description at all in Common Core of HOW you're supposed to do deal with kids who aren't learning everything well at exactly the right time.
