# Factoring Puzzle for Quadratic Trinomials

I’ve been a fan of this factoring puzzle for factoring quadratic trinomials since I worked through it at a Common Core workshop I attended (OGAP) in the summer of 2013.

Over the last couple of days, I have been going back through these resources that I originally blogged about and giving each resource its own individual page.

You might be interested in a few of these new pages like The Constant Chair Regression Activity or The No Fives Dice Activity for Modeling Exponential Decay.

It is my hope that this re-organization will make it easier for teachers to find much-needed resources when they are searching my blog.

I consider this factoring puzzle (page 20 of this PDF) to be my first exposure to open middle style problems.

I have always found it inspiring to look through the Resources for Algebra Blackline Masters shared online by the Public Schools of North Carolina.

Now that I am digitizing many of my activities that I used to do with laminated paper (and hope to be able to do so again in the future), I decided this was a prime candidate for digitizing.

## Digital Versions of Factoring Puzzle for Quadratic Trinomials

### Google Slides

I created a google slides version of this factoring quadratics puzzle.

### Desmos

Kathy Henderson turned this into a Desmos version, as well. Students use the drawing tools to fill in the missing boxes.

## Printable PDF Version of Factoring Puzzle

I know the original was already in PDF form, but I wanted to format the puzzle to look like the rest of my activities. Silly, I know.

## Puzzle Solutions

I intentionally do not make answers to the printable math puzzles I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.

However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.

If you are a teacher who is using these puzzles in your classroom, please send me an email at sarah@mathequalslove.net with information about what you teach and where you teach. I will be happy to forward an answer key to you.
