Order of Operations Posters

Download a free printable order of operations poster set for your math classroom. Each section of the poster easily prints on colorful letter-sized paper to create an eye-catching display.

One of the first decorations that I hung up in my high school math classroom after waiting an agonizing 10 days for the new wax to dry was this order of operations poster set and my grouping symbols poster which I always hang next to the order of operations.

Different Methods of Teaching the Order of Operations

PEMDAS? GEMDAS? GEMA? GEMS?

It doesn’t matter which acronym you choose to use to teach the order of operations, you should be able to modify these order of operations posters to work for you and your classroom!

The file for these order of operations posters contains all of the letters you would need for PEMDAS, GEMDAS, GEMA, or GEMS. The file for these posters includes the letters P, E, M, D, A, S, and G.

I’ve decided to make the transition from PEMDAS to GEMDAS.  In the past, I’ve always thought that I should just use PEMDAS because that’s what my students have been taught in the past.  

Please Excuse My Dear Aunt Sally is pretty ingrained in my students’ brains.  The actual order of operations and what it means is less ingrained.

After making my grouping symbols poster, I started toying with the idea of using G for “Grouping Symbols” instead of P for “Parentheses.”  I decided to go for it and use GEMDAS.  

Even if my students still think PEMDAS when they think order of operations, I hope that I can really emphasize the different grouping symbols that can be used this year.  (And, if you still want to do PEMDAS, I included a “P” at the end of the file, too!)

Printing and Prepping these Order of Operations Posters

I printed my order of operations title poster on 11 x 17 cardstock. This size of cardstock is my go-to for making posters for my classroom because it allows me to make my font just a bit bigger which allows students to see it from across the classroom.

I also used the same 11 x 17 cardstock to print my grouping symbols poster.

I printed the letters in GEMDAS on colorful astrobrights paper. I ran each page through the laminator and assembled them on the door of my classroom.
