3.NF.A.1: Understand unit fractions, such as 1/*b*, as the quantity formed by 1 part when a whole is partitioned into *b* parts. Understand *a*/*b* as *a* parts, each of size 1/*b*.

3.G.A.2: Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. *For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.*
