OH.GSS. Geometry and Spatial Sense: Students identify, classify, compare and analyze characteristics, properties and relationships of one-, two- and three-dimensional geometric figures and objects. Students use spatial reasoning, properties of geometric objects, and transformations to analyze mathematical situations and solve problems.
GSS.4. Grade Level Indicator: Transformations and Symmetry: Draw lines of symmetry to verify symmetrical two-dimensional shapes.
GSS.H. Identify and describe line and rotational symmetry in two-dimensional shapes and designs.
