Elementary Mathematics Common Core Crosswalks

Look for this document produced by the USOE to help teachers transition to the common core.  It is written from the vantage point of the old Utah Core, and adds interpretation and changes to help teachers be better prepared for the transition at hand:

• Black – Similar to 2007 Utah Math Core

• Green – New

• Red – Moved to another grade

• Blue – Concept is no longer in the elementary core
