After the success of using a quadratic formula template in my quadratic formula foldable, I decided to create a quadratic formula dry erase template for my students to use throughout the rest of the quadratics unit.

My first attempt at creating a quadratic formula dry erase template was rather simple. I created these to help my students organize their work while working through our Quadratic Formula Question Stack Activity.

The cards I use are hand-written because I made them last year before I had a computer template, so I don’t have a set to share. Sorry! (But, you can learn more about Question Stacks here.)

We slid them into these dry erase pockets to make them erasable and reusable.

If you don’t have a classroom set of dry erase pockets, you could also use heavy duty sheet protectors. But, I highly recommend investing in a classroom set of the pockets since they are so much more durable.

**MATH = LOVE RECOMMENDS…**

I cannot imagine teaching math without my dry erase pockets! They instantly make any activity more engaging and save me countless hours at the copy machine since I can use the same class sets of copies year after year.

Here are my current go-to recommendations:

The kids insisted we get out the red/yellow/green cups so they could indicate when their group was having trouble.

The thing that I liked the best from this was that when a group was having problems, it was super easy for me to figure out if they had even set up their problem correctly since that’s where I find most errors occur when working with the quadratic formula.

I tweeted a picture from this lesson, and John Golden suggested using different shapes for a, b, and c.

Of course, I had to pretty-up my dry erase template for the future, so I created two versions.

Version 1: Regular Rectangles

Version 2: Different Shapes
