achievethecore.org yet? It's an amazing website with SO MUCH stuff (for lack of a better word) all about the Common Core. There are checklists and sample problems and articles and advice for aligning textbooks & materials and even some really good videos about the shift to Common Core and classroom lesson videos. The picture above is from one of my favorite videos on the site, by Phil Daro, that really shows why other countries are passing the U.S. in math and why something needed to change.
If you're going to be teaching the Common Core Standards next year, you seriously need to check out this site. But come back to it often because there's so much there - I still discover something new every time I go back!
