Many professional associations have put together their own set of resources on the Common Core, typically from a pro-implementation stance. (View them with a critical eye, of course.) Here is a list of some of the more prominent collections.
Common Core State Standards Initiative Official site
The Common Core State Standards Initiative website provides comprehensive access to the standards themselves and state-level policy information. Download or view PDFs of the English Language Arts Standards (and Mathematics Standards too of course.) They maintain an interactive map of which states have adopted the standards and various FAQ documents About the standards.
ASCD's Common Core Resources
ASCD has developed a Common Core resource page and hosts meetings and webinars. ASCD has a twice-monthly, topic-based newsletter, Core Connection, that you can subscribe to by filling out a brief survey. And there's a hashtag to follow on Twitter at #ASCDcore.
Hunt Institute's videos on Common Core
The Hunt Institute's YouTube channel has lots of short videos, primarily featuring David Coleman and Sue Pimental, explaining aspects of CCSS. Several of the more writing-relevant are here in the LCC community. On the YouTube page you will find dozens more as well as to Spanish translations. They also offer a Video Vignette User Guide (PDF), which helps break down the content of the videos.
The Teaching Channel videos
The Teaching Channel also offers an even wider selection of videos about the Common Core, from broad overviews to lesson ideas for specific standards. We have included a piece by Kevin Hodgson where he analyzed one of their videos on Ted-Ed. Touche'.
Achieving the Common Core
David Coleman and Sue Pimental, two leaders of the ELA standards-writing team, have formed a non-profit organization to support standards-based education reform. They have a CCSS resource page called Achieving the Common Core with PPTs, fact sheets, side-by-side comparisons of the CCSS and other benchmarks, videos, and lesson plans. They have a "On the Road to Implementation" guide and have developed a Common Core Comparison Tool to support states as they compare their existing standards with the CCSS.
American Association of School Librarians (AASL) Standards for the 21st-Century Learner Lesson Plan Database
The American Association of School Librarians (AASL) Standards for the 21st-Century Learner Lesson Plan Database was designed to support school librarians and educators more broadly in teaching the skills associated with the AASL Standards for the 21st-Century Learner. Lessons in the Lesson Plan Database are reviewed by AASL and are aligned with AASL's Standards for the 21st-Century Learner and are crosswalked with the Common Core Standards.
