Give your class a concrete example of exponential growth and decay using this hands-on activity. These Algebra II lessons allow for the exploration of exponential growth and decay models, as well as the discovery of the patterns of each. Exponential sequences are also compared to linear sequences by identifying repeated addition, or multiplication.
