• 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.
