**Reason with shapes and their attributes **

**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.

**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. **Possible Activities:**
