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!

Thank you for sharing this lesson! I remember reading the book several years ago.
How many of your students have seen the movie or read the book?
I would like to see a copy of the additional attachment.
I love intertwining a movie or video in a math class, it’s so unexpected. I have not seen “Pay It Forward”, but I am willing to try the lesson out with my students based on your success and students’ enjoyment. Is the book an “enjoyable” read? I would also like to see the additional attachment. Thank you for sharing.
I found a good website that has clips of movies with math in it. Here is the link for the Pay it Forward piece. Could I also get the attachment for this lesson. Great idea, can't wait to use it. Thanks

This site is great. If you are looking for some trig ideas, be sure to view the GI Joe clip about "spherical trig." Clip uses 3D projection to show angles being labeled with Greek letters. Again, great site!
Hi. Thanks for sharing. I haven't seen the movie, but I viewed the clip that Jeanine posted. This looks like a great opportunity to teach students about the value of doing good deeds for others while teaching them about exponents. This looks like a great lesson, and I would like to try it with my students. I would also like see the additional attachment.
Thanks for the lesson! I had to modify it just a bit for my special ed population by moving the book lecture to another day.
