Mathematical Processes 
Work meets standard of excellence 
Work meets standard of proficiency 
Work meets acceptable standard 
Work does not yet meet acceptable standard 
Communication 
Uses effective and specific mathematical language and conventions to enhance communication about line symmetry and rotation symmetry, and about designs 
Uses appropriate and correct mathematical language and conventions to support communication about line symmetry and rotation symmetry, and about designs 
Uses mathematical language and conventions to partially support communication about line symmetry and rotation symmetry, and about designs 
Uses mathematical and nonmathematical language and conventions incorrectly and/or inconsistently, which interferes with communication about line symmetry and rotation symmetry, and about designs 
Connections 
Makes insightful connections between pictures/designs and symmetry 
Makes meaningful connections between pictures/designs and symmetry 
Makes simple connections between pictures/designs and symmetry 
Makes minimal or weak connections between pictures/designs and symmetry 
Visualization 
Uses a visual representation to demonstrate a thorough understanding of line symmetry and rotation symmetry

Uses a visual representation meaningfully to demonstrate a reasonable understanding of line symmetry and rotation symmetry

Uses a visual representation simply to demonstrate a basic understanding of line symmetry and rotation symmetry

Uses a visual representation poorly to demonstrate an incomplete understanding of line symmetry and rotation symmetry
