Reason with shapes and their attributes  Cluster 1 

Standard 3.G.1: Understand
that shapes in diﬀerent categories (e.g., rhombuses, rectangles, and
others) may share attributes (e.g., having four sides), and that the
shared attributes can deﬁne a larger category (e.g., quadrilaterals). Recognize
rhombuses, rectangles, and squares as examples of quadrilaterals, and
draw examples of quadrilaterals that do not belong to any of these
subcategories.

Standard 3.G.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.
