Every shape is unique in itself, but many share similar attributes. In this lesson, students will put shapes into groups and their partner will guess why those shapes belong in a group together.

Learning Objectives

(Math.Content.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 that do not belong to any of these subcategories.
