# Clip 6/6: Post Lesson - Part 3

## Overview

One of the facilitators asks the question: How would you build on these ideas or observations? Where would you go next instructionally? Teachers discuss the question in pairs and then share ideas with the group.

## Teacher Commentary

COACH LINDA FISHER: Teachers raised many issues, such as the idea that rates have primarily been used for interest or tax and how the ratio of boys: girls notation is so similar to rate. Observers also talked about how it seemed natural for students to go from a small rate to a larger rate. This makes me think about how I can pose or design a question where it is more convenient to go from large to small or use a unit rate. What question would be more useful to hold the numerator constant? I also like the idea of trying to introduce some rates that don't involve time such as cost per gumball.
