Attached is an activity on choosing the best cell phone plan. Students are required to make a cost chart for each plan, find a mathematical equation for each plan and graph each plan on a coordinate grid. In addition, students will describe which plan is best for their group and then describe which plan is best for other people (depending on how many minutes per month an individual uses).
This activity works best for students arranged in small groups of 2 or 3 students. The answer to what cell phone plan is “best” can vary (depending on minutes). I like that students must justify which plan is best, and I am hoping that not all groups will choose the same plan as the “best.”
I haven’t run this activity yet, but once I do, I will add to this discussion to describe how students did.
Students will be required to display their chart & graph on flip chart paper and present their findings to the class. I feel that students will have multiple solution strategies while explaining their justification of which plan to choose.
Please provide feedback if you try this activity in your class as well.
