Closure You may wish to bring the class back together for a discussion of the findings. Once the students have been allowed to share what they found, summarize the results of the lesson. This lesson can be rearranged in several ways. The team who claims the fewest needed pairs goes first. If a team guesses wrong the other team gets to try, after seeing one more pair.
Teams alternate turns until one guesses correctly.
This game can be played in about 10 minutes per pair of teams, making it time consuming if the entire class is to have a turn. After these discussions and activities, students will have an intuitive understanding of functions and will have seen many examples of linear functions. The next lesson More Complicated Functions will introduce students more general linear functions. The Shodor Education Foundation, Inc.
