Mimicking rules for integer operations does not help students become doers of Real Math, and frankly doesn't often stick in their long term memory. In this episode Pam and Kim walk through a Problem String that helps students develop an intuitive understanding of integer addition!
Talking Points:

• Exploring the beach as a context
• Equations and number lines in context
• Carefully chosen numbers to avoid distracting cognitive load
• Subtraction symbol or adding a negative? Parentheses or not?
• Let students grapple, then support and help make sense of ambiguity
