- Understand the structure/behavior of exponential functions in relation to linear functions. (Linear functions/arithmetic sequences change by a common difference. Exponential functions/geometric sequences change by a common ratio.)
- Understand the characteristics of exponential graphs and tables, including how these characteristics appear in equations.

The bundle opens with a modeling task that builds on students’ understanding of linear growth and uses that understanding—along with a playful context—to launch into an informal exploration of exponential growth. The emphasis here is on tables and graphs.

Having seen exponential functions, possibly for the first time, students now have an opportunity in Polygraph: Exponentials to sharpen their understanding of the visual similarities and differences of linear and exponential functions.
