Description

This lesson focuses mainly on 3.NF.A.3--understanding that the size of a fractional part is related to the size of the whole. Students use pattern blocks to explore different-sized wholes, and recognize what happens to the size of a fractional part as the whole changes. Core Actions 1 and 3 are strongly present in this lesson.
