I like to really dig into an topic as pervasive Common Core. Thankfully, so does the Brookings Institute. While this article certainly takes a stance that Common Core is politically motivated, it is well researched and pulls together a great deal of information that would take most of us months of reading to get through.
Who exactly is responsible for Common Core? I wanted to know this to understand what the research and thought process behind some of these standards was. Thankfully, there are lists of the standards work groups complete with their credentials.
Jam packed with research exploring common questions about Common Core. This resource is great because you can dive into the whole thing for a thorough examination of the standards or you can go to individual sections that address questions you have about it.
