Standard Description of 3.G.A.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.
Standards preceding 3.G.A.1 are 2.G.A.1. Standards that are taught after students master 3.G.A.1 are 4.G.A.1. The Lumos Coherence map for 3.G.A.1 includes standards correlations, description and a list of apps, questions, videos, books and other resources related to 3.G.A.1
