How can we bridge from proportional reasoning to functional reasoning? In this episode Pam and Kim talk through a Problem String that moves students from proportional reasoning into linear functions.
Talking Points:
- Building Proportions Problem String
- Thinking about "between" and "within" relationships in a ratio table
- Slope, rate of change, similar triangles, equivalence: all figure-out-able
- Ratios and proportional reasoning to functional reasoning
- Slope is a ratio
