Math = Love: Free Classroom Posters

Free Classroom Posters

Since I started teaching high school math in 2012, one of my absolute favorite things to do has been to create posters to decorate my classroom with each year. I've created this special page on my blog to house all of these posters in one easy to find place. I have made them free for you to download and use in your own classroom as a way to say thank you to the thousands of people I've stolen teaching ideas from on the internet. For each poster, I have tried to provide both a PDF copy and an editable copy.  The PDF copy preserves my font choices, but you cannot edit it. If you download the editable copy, the fonts will change unless you have fonts I used installed on your computer. Almost all of the fonts I use can be downloaded from Font Squirrel.  

I teach secondary math (with a smattering of science along the way), but I hope teachers of other subjects and grade levels should be able to find some useful posters as well for their classrooms.  

The majority of these posters are made to print on letter sized paper. I often print these on colored cardstock and laminate for extra durability.  This lets me reuse the same posters from year to year. Occasionally, I design posters to be printed on 11 x 17 cardstock (affiliate link) or as 18 x 24 engineering prints which you can order from an office supply store like Staples. Though, if you look at my classroom pictures, you will realize that nothing tends to stay in the same spot. And, plenty of other posters get rotated in and out.  

I've tried to include pictures of these posters in my classroom, but if you want to see my classroom as a whole I will share those links, too.

  1. These are awesome! Thank you for sharing.

  2. Thanks so much for sharing all of these!

    1. You're very welcome, Nina! Hope you're able to find something to use!

  3. Thanks for sharing. I especially like the bulletin board with titles "Math makes wonders" and "Live. Math. Love" but the link does not work. Do you happen to have a link that works or the posters themselves?

  4. I am so excited to make use of your signs!!! I was feeling like what I had saved from my teaching (pre-children of my own) was so outdated and old looking!!! Thank you for sharing and saving me so much time!!!

  5. Unreal! Exactly what I was looking for. Thank you, thank you, thank you!

  6. Oh my gosh, I want all of these! Why do I not have enough wall space for all of these??

    1. Yes! We just need to invent classrooms with infinite wall space!

  7. Where were you 25 years ago? Or someone like you? I taught and homeschooled and it was when there was nothing available in our cattle country area. I would put up school stuff still if I could justify it! An old-time teacher who still loves it!

  8. Thank you for sharing all of these mam Hagan

    1. I just noticed that the Perfect Squares poster for 9 has 12 squares on it! Just wanted to let you know! I love all of your stuff. Thanks for sharing.

    2. And that's why they look like rectangles. Great discussion right there!

  9. Thank you so much. I've been wanting to improve the signage in my classroom for years. I'm pretty critical when people make signs (bad fonts, poor spacing) but yours are really top-notch. Thanks again!

  10. This makes decorating my classroom so much easier! Thank you!

  11. I do not get the clock arrows. Please explain! Thanks for all you do.

  12. I. Love. This. ALL OF THIS.

  13. Thank you for sharing these ideas. We love them in our school.

  14. Thank you for being generous and allowing us access to your hard work!

  15. Very nice Posters, thank you. But isnt it a Little bit too much stuff for the students? It might distract your pupils, what is your opinion about this thought?

  16. These are so great. I am going to use some this year in my classroom. Thank you for making my job easier!! Thank you for sharing them and allowing us to download and use your AWESOME ideas.

  18. I am a first year teacher and I have printed just about every resource from this page I think!!!! My FAVORITE is the welcome sign written with graphs. I have it above my whiteboard and it makes me so excited for my students to come into class and see it. Thanks for everything, much appreciated!

  19. This is my second year teaching HS math- 1st year teaching all day math at 4 different special ed. levels. These resources are the point it's 8:55 pm on a stormy Saturday and I almost want to make the five minute drive to my class to print them all out and hang them tonight. THANK YOU

  20. Since I've received so much help from you, I think that I should share how I have altered what I call the tower of operations. The left side has the word expressions spelled out from top to bottom, and the word equations spelled out from bottom to top. This really helped my algebra I students understand the basic principles/differences between simplifying an expression, and solving an equation. Here's my link:

    Thanks for all you've done for math teachers everywhere!
