Topic 11: Geometry Week 21-23 Domains: Geometry 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. Knowledge Targets “I Can” Statements Standard Interpretations Identify and define rhombuses, rectangles, I can compare and classify shapes based on In second grade, students identify and draw triangles, quadrilaterals, pentagons, and hexagons. Third graders and squares as examples of quadrilaterals their attributes. build on this experience and further investigate based on their attributes quadrilaterals (technology may be used during this exploration). Students recognize shapes that are and are not quadrilaterals by examining the properties of the geometric figures.
