I want to get an iPhone8 and maybe change my service plan. Which of the above plans should I choose?
Student pick one plan and consider the cost of the phone and plan over time. They make tables, graphs and equations. Consider allowing students to begin playing with the task without much initial instruction. Guide them with good questioning and teach after they have had time to grapple with these questions and construct new ideas.With our activity students select a plan and complete their graphs. Consider posting the graphs up on the wall (or over a document camera). Have the rest of the class identify which cell phone deal matches their graph. Finally students compare paying for the phone up front or with installment payments using T-Mobile, Verizon, Boost, Sprint or Consumer Cellular. Which will be the best deal in the long and short run?
