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.1. Grade Level Indicator: Characteristics and Properties: Identify, describe and model intersecting, parallel and perpendicular lines and line segments; e.g., use straws or other material to model lines.
GSS.5. Grade Level Indicator: Spatial Relationships: Describe points, lines and planes, and identify models in the environment.
GSS.B. Describe and identify points, lines and planes in the environment.
GSS.C. Describe and identify intersecting, parallel and perpendicular lines or segments in the environment.
GSS.D. Identify and draw right, obtuse, acute and straight angles.
