    I chose the Charge It problem. I did not read to the end and made the same assumptions that students would make. I like the idea of using this to model a piecewise function as my students have typically had trouble with these. I anticipated that the students would solve this using a table and looking for the average rate of change, by estimating that it is close to 1% per minute, by making a linear graph and then by solving a proportion. It took me a while to think of the different ways that students would do it since as a math teacher, I tend to jump right to the “mathiest” way!
