Intro to the Quadratic Formula

The first time a kid sees the Quadratic Formula, panic sets in. It's so long! What is that weird +- sign? Can't I please just factor?? I made this green poster on cardstock to hang on our math word wall. The white letters I made with white out to emphasize where we have to add our A, B and C values.

 Free Quadratic Formula Warm-up Template

This is the template I created this year for the Quadratic Formula. after becoming obsessed with warm up templates. On the front board, I shine the slide below. Students then copy the given equation onto their template and solve with using the Quadratic Formula. 

You can get the template and Powerpoint slides in the sidebar "Freebies" section. You can also check out this post for more free Algebra and Algebra 2 warm up templates

Quadratic Formula Pennant

This Quadratic Formula pennant is a fun way to assess student understanding of the Quadratic Formula while also decorating your classroom with math. 

Here is a "skeleton" (I need a better word for this) Quadratic Formula that you can paste into worksheets if your students need more help. I eventually pull this skeleton away but find that it is really needed at first. 

We summarized our Quadratic Formula understanding wit this paper chain activity. All of the problems can be factored, but I find that my students all choose to use the formula. 

Quadratic Equations Chain Activity

We then move onto solving quadratics with the graphing calculator, which you can read about here
