Mathematical Processes 
Work meets standard of excellence 
Work meets standard of proficiency 
Work meets acceptable standard 
Work does not yet meet acceptable standard 
Problem Solving 
• develops a thorough plan for solving the problem • chooses an efficient and effective strategy: may demonstrate creativity and innovation in designing castles 
• develops a workable plan for solving the problem • chooses an appropriate and workable strategy to design castles 
• develops a basic plan for solving the problem • chooses a simplistic and/or routine strategy to design castles 
• develops a minimal and/or flawed plan for solving the problem • chooses an inappropriate or unworkable strategy to design castles 
Visualization 
• uses insightful visual representations to show an array 
• uses meaningful visual representations to show an array 
• uses simple visual representations to show an array 
• uses unclear visual representations to show an array 
Connections 
• makes insightful connections between division, multiplication, and arrays 
• makes meaningful connections between division, multiplication, and arrays 
• makes simple connections between division, multiplication, and arrays 
• makes minimal or weak connections between division, multiplication, and arrays 
Mental Mathematics and Estimation 
• demonstrates computational fluency that is efficient and flexible 
• demonstrates computational fluency that is workable and understood 
• demonstrates computational fluency that is routine and familiar 
• has difficulty in demonstrating computational fluency and must work through procedures
