Connections 
• demonstrates a sophisticated ability to transfer knowledge and skills to new contexts 
• demonstrates a consistent ability to transfer knowledge and skills to new contexts 
• demonstrates some ability to transfer knowledge and skills to new contexts 
• demonstrates a limited ability to transfer knowledge and skills to new contexts 
Visualization 
• uses visual representations insightfully to foster/demonstrate a thorough understanding 
• uses visual representations meaningfully to foster/demonstrate a reasonable understanding 
• uses visual representations simply to foster/demonstrate a basic understanding 
• uses visual representations poorly to foster/demonstrate an incomplete understanding 
Communication 
• uses effective and specific mathematical language, symbols, and conventions to enhance communication
• provides a precise and insightful explanation of mathematical concepts and/or procedures 
• uses appropriate and correct mathematical language, symbols, and conventions to support communication
• provides a clear and logical explanation of mathematical concepts and/or procedures 
• uses mathematical language, symbols, and conventions to partially support communication
• provides a partially clear explanation of mathematical concepts and/or procedures 
• uses mathematical and nonmathematical language and conventions incorrectly and/or inconsistently that interfere with communication • provides a vague and/or inaccurate explanation of mathematical concepts and/or procedures
