This is a lesson that I learned in Algebra for All Year 1, to teach exponential functions. I used this in my Algebra I classroom. The concept is modeled after the theme of the movie, Pay It Forward. Students really enjoyed this activity and I use it in the section to introduce exponential functions. There is another attachment that goes with this lesson. If you choose to use this activity, please comment, I would love to hear your feedback! Thanks!
Thanks for the lesson. I plan to use it in the future with my algebra students. I made a few minor changes, because of time allowance. I still plan to teach the lesson over 5 days. I added some real-life applications with compound interest and bacteria growth. The science and economics departments usually teach these concepts around the same time. I think a little cross curricular teaching will help the students master the concept of exponential growth.
I would love to use this lesson as an intro to exponential functions. This is my first year teaching this concept so please send me the other attachment! I really like what is here so far and plan to use it.
I use his as an intro to exponentials. I really wish there was a site like this one when I was a first year teacher. If you have a lesson idea that you like make sure you share it with the rest of our community:)
