If you teach math, you might find a new guide to the common standards useful. Released today by the National Council of Teachers of Mathematics, the guide tries to build a bridge between its own math standards, which are widely used in schools across the country, and the math in the common standards. The new set, as you know from reading this space, has been adopted by 43 states and the District of Columbia, so lots of school folks are asking for guidance implementing them.
The NCTM's guide includes both a print version and an online interactive version.
Other resources compiled by the NCTM for the common-core standards have been gathered together on a special page on its website. They include a Power Point presentation on the standards, separate presentations divided up by grade span, and a report of a joint task force of mathematicians and math educators about what is needed to implement the new standards well.
