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
