Bring the real world into your classroom with this activity. The students will be given some real world information about the elk population in the Great Smoky National Park. They will then be given a scenario where they have to track the growth of the elk herd. Once the students have a table, they will create a graph to visually see their data. They will determine if their data is linear, exponential, or quadratic by figuring out a regression for each and seeing what works the best. The students will defend why they picked the regression they did and then use the equation to answer a question. To incorporate some critical thinking, the students will be asked to describe a scenario that would create the other two types of regression not used.
