Iphone 5
This is only part of the infographic published and copywrited by AVALAUNCH MEDIA. We’ve left off the solution of this graphic so that your class can come to their own range of iPhone5 costs. To see the full graphic go here.
When you look at the infographic what do you see? What does it make you think? What do you wonder?
You might have heard that you can get an iPhone 5 for as little as a couple hundred bucks, but is that all it really costs? What is the real cost of an iPhone 5? If I want to upgrade from my non-smart phone to the iPhone 5, how much will it cost me? Which iPhone 5 should I get? Which provider offers the best long term value?

Here are some additional activity ideas:
8.EE.8 T-Mobile recently started charging $580 for the iPhone 5. For service you get unlimited talk and text and they charge $50 a month for 500 megabytes, 2 gigabytes is $60 or unlimited use is $70 a month. How do these deals compare to those of Verizon, AT&T and Sprint (consider comparing for 1 year, 2 years or more than 2 years)? This could be an interesting way to explore or intro systems of equations.
7.SP.8 Using just the data in the infographic how many different ways can I purchase (capacity and contract or no contract) and sign up for service (plans from three different companies) with an iPhone 5? 6 x 7 = 42
8.F and HS.F We just learned from the prior example that in the infographic alone there are 42 different ways to buy and have service for an iPhone 5. Have students randomly pick anyone of them to graph. Students should graph the cost of the phone and their plan over 12 months. The cost of the phone is the y-intercept and the monthly cost of the plan is the slope. Have kids hold off on revealing which combination phone/plan they graphed. Have other students or the entire class figure out which combinations are modeled in each graph. This can be done in groups, a gallery walk or sharing at the ELMO. This offers a relevant context for linear relationships.
HSF-LE Want to get into exponential models? It has been said that the iPhone keeps about 63% of its value after a year. If that rate of depreciation continues over the life of the iPhone find the value of the 64 GB iPhone 5 after 1, 2, 3 and 4 years. According to your model when will the phone be worthless?
