## Reflection: Discourse and Questioning Two Methods, One Equation: Finding the Boundary Line - Section 3: Discussion + Closing

There is a good opportunity here to get students talking to each other and building on each other's reasoning.  One goal of the discussion section might be to get a student who prefers one method of graphing inequalities to try and explain the other method.  Anytime we have multiple solution paths in a problem, we have an opportunity to generate student discourse in the classroom. I might do that by asking students to repeat or rephrase what another student said or ask someone to add on to another person's thinking.

## Big Idea: Hey, how did you find that line? Students examine two different ways to find the equations of boundary lines and work to understand why they are equivalent.
