Which cell phone plan is the best for me?
In this lesson, students are given a scenario that requires them to create a linear equation, complete a table and graph the function. The problem presented to the students is as follows: I am sorry to inform you, but your parents have decided to take you off their cell phone plan. Three cell phone plans are provided to different groups in the class. Students are to work in small groups to create their equation, after which they move to larger groups to construct a poster to present to the class. After working in large groups the class will come together and discuss all three cell phone equations and compare. Finally, students will individually decided which cell phone company fits their lifestyle and justify their conclusion. In this activity students will model with mathematics and create linear equations through an interactive activity that appeals to their age group.
