You can find an up-to-date mapping of our content to the Common Core Standards here.
This is a work in progress, and we’re regularly creating new content to rigorously and comprehensively cover the Common Core Math Standards. Like the authors of the Common Core Standards, we believe that conceptual understanding, procedural fluency, and application are all critical and complementary components of an excellent math education.
As the Standards become more widely implemented, we want to make it easy for students, teachers, and parents to find the content they need on our site.
