Utah Core Standards
UT.5.G. GEOMETRY (5.G)
Graph points on the coordinate plane to solve real-world and mathematical problems in quadrant one (Standards 5.G.1–2). Classify two-dimensional figures into categories based on their properties. (Standards 5.G.3–4).
5.G.3. Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and all squares are rectangles, so all squares have four right angles.
5.G.4. Classify two-dimensional figures in a hierarchy based on properties.
