Algebra 2 INB Pages - Exponential Functions, Exponent Rules, and Factoring

Unit 3 was a weird one for Algebra 2.  I wanted to cover exponential functions right after linear functions to see if teaching y=a+bx actually helped my students to graph y=a(b)^x.  I also needed to review exponent rules with my students before we could move onto quadratic functions, radical functions, or logarithmic functions.  And, I also needed to make sure that my students were solid on the distributive property, combining like terms, and factoring before we got any further into the semester.  So, I sort of combined all of these into a hodgepodge Unit 3.

Exponent Rules

Ms. Hagan's Book of Exponent Rules worked so well with my Algebra 1 students that I decided to try it out with my Algebra 2 students.

Introduction to Factoring Notes
If/when I ever do this again, I will type up the polynomials that are written in marker.  Students will have to cut them out and decide if they are the factored version or the distributed version.  Students will glue them in the appropriate places on the table and then come up with the corresponding version.

I used the same factoring graphic organizers with my Algebra 2 kiddos that I used with my Algebra 1 kids.  You can read more about my approach to factoring this year here.

We closed out the unit with an exponential growth and decay of skittles lab, but that will have to be another post for another day!

  2. Logistics question for you: do you fill out your INB page while students are completing theirs, or do you have it pre-filled in? And, do you have a document camera?

    1. I have a document camera. But, I usually only use it to demonstrate calculator keystrokes. I usually make a version of the graphic organizer or foldable that I fill out on the Smart Board. I write it as I ask the students to write it.

  4. I used X-puzzles to teach Algebra 1 factoring today. It was fantastic! Thank you for your ideas and your willingness to share them.

  5. Sooo, I used the difference of squares organizer today! And while I was at it, I used your example on it too, and I totally forgot to factor out the GCF (9) at the beginning!!! I'm terrible at remembering that (my biggest algebra weakness), but I love the whole set of factoring graphic organizers you shared. :)

    1. I have a tendency to forget that too in the midst of teaching! I need to do a better job of making my graphic organizers emphasize that.

  6. Love your blog! My students are loving the "slide, divide, bottoms up", thanks for your work. :)

  7. Hey Sarah,

    I'm hoping to use some of your notes pages, but I can't see the downloads for the PDF documents anymore. Can you help me out? I'm hoping to use the ones for factoring! Thanks!

    1. Sorry about that! Here's a searchable link of all my files. The site that hosts my files has been having issues. :( https://app.box.com/s/abl3ycndkyzb7jcujpdf

    1. I figured it out. You reduce the fractions and then do bottoms up. I have never seen this method before but really like using it. My students have also picked up on it quickly.
