Students will:

• Interpret real-world contexts involving positive and negative rational numbers
  
  
• Represent addition and subtraction on number lines (use with included or custom number line graphic)
  
  
• Rewrite subtraction as adding the opposite using additive inverses
  
  
• Apply commutative and associative properties to simplify expressions
  
  

Perfect for classroom practice, assessments, or targeted intervention!
