Common Core and Math

Check out the tree below to get an idea of how the middle school math content in the Common Core fits together for 7th and 8th grade. Clusters of standards are indented once, while the standards themselves are indented twice.

Click on one of the blue links to see problems and exercises related to a cluster or standard, often broken out by the specific skills that standard encompasses. If there’s no link for a standard, that means Opus doesn’t have any problems for it yet. New content appears all of the time, so if you don’t find what you want, please check back soon—or drop us a note by clicking “Contact Us” in the bottom right, and we’ll get right back to you. You can also upload Word documents or PDFs to put your own problems in the bank.
