Anchor Standard:
Grade Specific Standard:
G.1 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
Information Technology Standard:
Clarifying Objectives:
Distinguish between defining and non-defining attributes and build and draw shapes to possess defining attributes
