Students compare cell phone plans by analyzing tables, graphs, and equations in this sample lesson. Tools are available and useful to students during their analysis, and provide opportunities to make sense of the different rate plans.

Students are also encouraged to share their thinking with their classmates, and report their findings to the class.
