MAT-03.G
Narrative for the (G) Geometry DomainGrade 3 students analyze, compare, and classify two-dimensional shapes by their properties. They explicitly relate and combine these classifications. Because they have built a firm foundation of several shape categories, these categories can be the foundation for thinking about the relationships between classes. Students investigate, describe, and reason about decomposing and composing polygons to make other polygons. Problems such as finding all the possible different compositions of a set of shapes involve geometric problem solving and understanding of congruence and symmetry Students in Grade 3 also develop more competence in the composition and decomposition of rectangular regions, spatially structuring rectangular arrays. They count by the number of columns or rows, or use multiplication to determine the number of squares in the array. Calculation Method for DomainsDomains are larger groups of related standards. The Domain Grade is a calculation of all the related standards.

MAT-03.G.01MAT-03.G.01 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. Draw examples of quadrilaterals that do not belong to any of these subcategories. |
