With so many models, what role do equations play? In this episode, Kim takes Pam through a Problem String that can only be modeled with equations and shares why.

Talking Points:

• Fibonacci Day
• Utilizing choice is a mathematical behavior
• Differentiating instruction through strategies
• Swapping, not a major strategy, but a fun one
• Models vs. Strategies
• Equations as models for equivalance strategies
