Standard

Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

Student Language:

• "I can understand and tell about the parts that make different shapes unique."
• "I can build and draw shapes that have certain parts."
