Algebra One Unit 7 Exponential Functions

Now we get into the fun stuff!  Applications....

I like to start off by considering a new type of function. A fun way to do this is with a skittles lab (or M&Ms) which I'll detail in my next blog post.

From there we define in a general way exponential functions and then compare linear and exponential functions. We look at the difference between growth & decay. Then we explore additional applications by looking at Half Life, Compounding Interest and Logistic Functions. Also we do some regression analysis of exponential data.

I'm not going to go into a lot of detail on these now as my student teacher covered these topics in 2014-2015 school year. But I will do an update in spring 2016 after I teach it and tweak all my ISN inserts.

For now, here are the inserts my wonderful student teacher used.









 Regression Analysis pages:
first a reminder of how to use the graphing calculator

 then an example:
 Other Applications:

Space was limited in this foldable so next year I'm thinking of creating two two page foldables for these four topics.


Here are some worksheets and lesson materials I used for these topics.

  1. This is great! I am a student teacher and I am looking for an interactive way to introduce exponential functions to 9th graders
