This skittle activity has students conduct two experiments that show the differences in linear and exponential tables, graphs, and rules. Each person needs a mini bag of skittles (another option: buy a bulk bag and put about 40 skittles into ziplock bags or cups). Each partner follows the direction on the handout then trades their data with their partner. Partner 1 should have an exponential set of data since they are taking away roughly half of their skittles each time. Partner 2 should have a linear set of data since they are taking away 1 or 2 skittles at a time. Students are able to see the differences in the linear and exponential data sets and graphs. After they graph their data, this activity has students estimate a rule and then do regression in their calculator to obtain an exact rule. Students love eating the skittles!
