  • Assessment Anchor - M03.C-G.1 Reason with shapes and their attributes.
    • Anchor Descriptor - M03.C-G.1.1 Analyze characteristics of polygons.
      • Eligible Content - M03.C-G.1.1.1 Explain that shapes in different categories may share attributes and that the shared attributes can define a larger category. Example 1: A rhombus and a rectangle are both quadrilaterals since they both have exactly four sides. Example 2: A triangle and a pentagon are both polygons since they are both multi-sided plane figures.

        • Alternate Eligible Content - M03.C-G.1.1.1a Identify similarities between two polygons.
          Alternate Eligible Content is designed for students assessed using the PA Alternate System of Assessment (PASA). Essentialized Example resources assist teachers in designing instruction that reduces content complexity while maintaining alignment to academic standards.
      • Eligible Content - M03.C-G.1.1.2 Recognize rhombi, rectangles, and squares as examples of quadrilaterals and/or draw examples of quadrilaterals that do not belong to any of these subcategories.
