Parts of a Set

This week we carried our practice subitizing small sets a bit further.  Given a set of four rocks, one child acted as the “teacher” and covered any number of rocks with their hand.  The second child, “student”, then deduced how many were hidden.  They used their knowledge of “four” and the visual clues showing how many were still uncovered.  Subitizing and working memory united to build on the children’s growing understanding of sets.
