Reply To: Lesson 5-6: Question

[Karynn Faivre]

At the beginning of this past year, I started with a lesson on proportions/ratios and wanted it to lead into a lesson about writing an equation of a line. I had students plot 2 points using desmos graphing calculator. Then their partner tried to write an equation that connected those two points. Reflecting on that lesson, I should have pivoted to many more lessons that require proportional reasoning, but I would do a much better job of connecting to different representations. I also realized that students could easily extend to given whole numbers but did not have equal success with decimals as in your defrosting problem. Much more time should have been spent helping students develop their number sense.
