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

14. My stepdaughter switched to a new school in the 2nd grade

when we became a family. In her old school she had barely squeaked through, graduating first grade by the skin of her teeth. Her reading and math scores were abysmal.

The new school she entered had just become the pilot school in the Riverside district for the new Common Core curriculum (they call it Core Knowledge here) and everyone was excited to try it out.

By the end of the second grade she had made tremendous improvements in her academic achievements, had become a voracious reader, learned to actually enjoy math, and had developed a genuine interest in learning about anything and everything. She's now a fourth grader and has accumulated more AR points (a point score awarded for reading and passing tests on books, each of which is rated for grade level) than the entire 1st, 2nd, 3rd, 4th, and 5th grades put together! She regales me daily with information about Chinese dynasties or whatever else her class is learning about.

Common Core may have issues and may not work for everyone, and may be saddled with ideological baggage to which I am not privy, but from a sheer learning perspective it seems to have been an enormous boon for my little girl.
