[quote=indigo] I've been looking for sources, can you point me to where you find these standards?[quote]

You may be interested in this document in particular "Designing High School Mathematics Courses Based on the Common Core State Standards"

It outlines four pathways, two of which are compacted to allow for the study of calculus or other college-level mathematics courses in high school. Ultimately, what will affect what our kids can do is not determined so much by the Common Core Standards as they are by how individual school districts implement them. I'm going to keep a careful eye on what my DD (11, grade 6, taking Algebra I next year) is learning in her classes and supplement as necessary.
