This worksheet is designed to replace a lecture on the topic of exponential decay. For them to be successful with this activity, each group will need a set of 100 pennies: at each step, they flip the pennies in bulk, and remove all of the heads. Because they know that about half of the pennies will be removed each time, they get a good idea of what a decaying exponential really looks like.
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
