Cluster 6: Exploring parts and wholes with joining and separating

In this cluster, students determine the amount in a set either by counting, counting on/counting back, subitizing, or
using other number relationships. Students continue to explore part-part-whole relationships to see that we can solve joining and separating word problems. Students’ work in this Cluster making connections between composing/decomposing 10 and solving story problems will lay the foundation for their work with teen numbers in Cluster 7. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
