Quadratic Functions Foldable

I've been meaning to share this foldable for a couple weeks now, but I finally decided to do it now because I was just on Pinterest and noticed that someone had pinned a picture that I had posted of my students using it.

Quadratics are always such a difficult concept for my students. I think part of it is that they "hate graphing" before we even get started and then the fact that there are three different forms of a quadratic function helps to confuse them even more. I wanted a foldable that would be helpful in organizing all of this information.

We were working on graphing quadratics with standard form, vertex form, and intercept form (which I've also heard as factored form) before Thanksgiving. We worked on this foldable the day we came back from Thanksgiving which was a nice review, but also a nice lead in for writing quadratic functions.

Here is the closed foldable. It is meant to go in their notebooks vertically like this. Then they can pull out each section as they need it, like so...

For each form, I included how to find the axis of symmetry, the vertex, any other miscellaneous information (x- and y- intercepts) and a sketch of an arbitrary graph with the important information from that form.








And here is the file for the foldable:







The fonts in the pictures are a little bit different because I used some dafont.com fonts which wouldn't work on a computer that doesn't have those fonts downloaded. If you want fun fonts just head over to dafont.com and be prepared to spend hours downloading fun fonts...or maybe that's just me?

Basically for all of my foldables the "thick" lines are for cutting, the dotted lines are for folding and the "regular" lines are just used to separate sections.

I called it a "springy" foldable when I was naming the file, but then while we were working on it in class I told them to fold the strips like an accordion and I liked that better...so accordion quadratic foldable it is! Enjoy!!

  1. I'm loving the accordion fold! This is a new foldable format to me, and I'm excited to find a way to fit this into my interactive notebooks this semester. Thanks so much for sharing!

  3. Thanks, just what I was looking for. I needed a foldable idea for our quadratic graphing unit. We start graphing next week and I was coming up blank. Thanks for sharing.

  5. I'm a high school math teacher as well. And looking for math ideas one blog brought me to another and another and I ended here. I really find your ideas supportive and useful. I haven't been on my blog in for while, and forgot how to follow another blog. (Lame, I know..) How can I follow this blog? I really want to.
    That's it.. Thank you!

    1. Meredith,

      Thanks for stopping by and for your interets in following. I just added a bar on the side where you can follow the blog by email. I'm pretty sure if you use google reader or something else similar then you can just copy and paste the url into your reader to follow. I hope this helps!

    1. Hi Joy,

      Are you using a mobile device or tablet to view the page? I'm guessing yes because you should be able to see the file right on the page, where you can download, print and share it. Here is the url for the document on box.com https://www.box.com/shared/q2a2n2x675sh977n8rjo

      Thanks for stopping by :)

  7. This was exactly what I was looking for! I wanted to review the different forms of quadratics with my honors precalculus class, and this foldable did just that! Thank you so much for sharing!
