Yep, Apple just announced a new iPhone ... the iPhone 7. It will be in their stores on September 16, 2016. What will their record sales be like this time? How many iPhones will they sell?

In this activity kids explore past iPhone launch sales data and predict how many iPhone 7's will be sold during the opening weekend in 2016.

Younger students can investigate the data through a bar graph, while older students can use a scatter plot and even use equations to model sales growth.

**Technology**: Students can model the data with linear, quadratic or exponential models at this interactive Desmos graph or this Desmos Graphing Activity the data and sliders are all set to go. Let your students rough out their models & predictions as they work through the activity.
