Cluster 3: Stories with Addition and Subtraction

The focus of the work with addition and subtraction in third grade is to build on the conceptual understanding developed in second grade and to develop procedural fluency within 1000. Work with NC.3.OA.8 begins in this cluster as students have now had experiences with multiplication and can begin to think about two-step word problems with addition and subtraction and some simple multiplication. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
