Proportions & Ratios: Lesson Planning (Part A)
In this clip, Linda Fisher, Carolyn Dobson, and Hillary Lewis-Wolfsen
discuss the idea of "re-engagement" and what they hope the fifth grade students and observing teachers will get out of the demonstration lesson on proportions and ratios.
To prepare, they picked out some interesting work on the task "Candies," a fifth grade assessment, to show teachers a variety of strategies and models used by students to make sense of the problem as well as to present common misconceptions.
