To finish this lesson, the instructor randomly calls on a student to come to the front of the class and show her work on the projector. Students then say whether or not they agree with their peer's answer. As a follow up to the work they've done in class, the instructor asks students to do a "think, pair, share" and talk about which method of graphing linear equations was easiest for them. Finally, students are provided with an exit sheet containing an exercise they must complete and return to their team folder before leaving.
