Our first unit in Algebra 2 is an introduction to functions, function notation, domain and range, intercepts, maximums and minimums, intervals of increasing and decreasing, finding solutions, and transformations. My goal is to create a foundation which I can build off of once we start linear functions. I am also working hard to prove to my students that they are capable of doing Algebra 2 level work. Many of my students have extremely low confidence. We are also learning how to use the graphing calculator. This is the first experience any of my students have had with a graphing calculator, and I am working hard to make it a positive one.

So far, my Algebra 2 students are loving our interactive notebooks. They thank me on an (almost) daily basis for making Algebra 2 visual, fun, and easy. I have some students who are complaining right now that Algebra 2 is too easy. I told them that they just had to wait. Before they knew it, we would be exploring logarithms, exponentials, conic sections, and all kinds of other exciting mathematical relations. After going on and on about how excited I was about everything we were going to be learning and studying this year, one student asked, "Do you like math?" I was a bit taken aback by this question. Are there math teachers who don't like math? Of course, I like math. I love math! I eat, breath, and sleep math.

You'll notice that I love printing my foldables on colored paper. I think that notes taken on colored paper are just more memorable than notes taken on plain, white copy paper. My students often remember which page in their notebooks they need to reference by what color the foldable was printed on. The paper I use the most is Fireworx brand colored paper. It's available from Amazon, comes in loads of colors, and is priced very reasonably. Astrobrights paper makes for the prettiest, brightest foldables, but it's a bit more pricey. So, I save it for printing posters.

I LOVED the envelope template that Kathryn (iisanumber.blogspot.com) posted earlier this summer. I downsized her template to the exact size needed to fit the domain and range cards I linked to earlier.

The Cutest, Tiniest Envelope to Hold our Domain and Range Practice Cards |

Domain and Range Foldable (That sadly doesn't photograph well...) |

The foldable is made to perfectly hold our domain and range practice cards that are housed in the envelope. |

After doing many, many cards together, I had students find the domain and range of all 32 cards as homework. They had to write the domain and range in both interval and algebraic notation. (And, the discrete graphs had to have their domain written in set notation.) The next day, I gave them an answer key to use the check their work.

A lot of my students were terrified when I told them that we would be learning about inverses. By the end of the lesson, they were amazed that inverses were actually quite easy.
