We've launched thousands of new peer-reviewed practice problems that rigorously cover the new US Common Core State Standards for Mathematics and can be used in your classroom today.
40+ states in the US have adopted the rigorous new standards that will change the way math is taught for 44 million students across the country.
Many of the teachers we’ve spoken to have been anticipating a big change and lots of uncertainty.
Our expert team of 15 teachers, tutors and professors have meticulously unpacked individual standards to build new problem sets designed entirely to test knowledge of standards on a deep level.
While we are still working towards full coverage of all standards and all grades, we are adding the new practice problems as they are created, so teachers always have the latest resources available.
We are also working on organizing our math content by grade level, in addition to our traditional subject-level view. This is also a work in progress, and will be complete by the end of the 2013–14 school year.
Enjoy exploring our new content!
See how each standard maps to Khan Academy problems, with complete coverage by summer 2014.
