Reflection: Staircase of Complexity Modeling Population Growth - Section 1: Opening


Students really struggled with the Warm Up activity in this lesson. In hindsight, I would have spent more time at the start of class reviewing arithmetic and geometric means prior to giving them the next task.  We ended up taking a majority of class time for the warm up, but I still think it is time well spent. The task that follows, Growing, Growing, Gone, is a more complicated problem because the intervals between the population data is set at 20 years. I think that with a fuller understanding of the warm up problem, students will experience greater success on the main task.

Modeling Population Growth

Unit 7: Functions
Lesson 10 of 11

Objective: SWBAT use their understanding of linear and exponential growth patterns to model the growth of a population.

Big Idea: What will the United States population be in the year 2030? Students use linear and exponential growth models to make predictions and argue about which model is the best fit for the data.
