Order of Operations Posters (GEMDAS / PEMDAS)

Today I want to share my new order of operations posters with you. Yesterday, I was allowed back in my classroom for what feels like the first time in forever.  

They waxed the floors, and we had to wait ten whole days for the wax to dry.  For a teacher who lives for decorating her classroom, this was pure torture.

One of the first decorations I put up was my GEMDAS Order of Operations Posters and my Grouping Symbols poster. I printed the posters on 11 x 17 cardstock.

Order of Operations Posters GEMDAS Grouping Symbols

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!)

I hit the print command twice, and then the dialog box came up. Try that

This order of operations poster deigns are unique and I like the designs. You can order in online of various Adshel poster sizes in Australia for advertising any business event. These posters are also well known as billboard posters and used widely throughout the Australia.

I too teach a "G" for grouping symbols. And, I use "GEMA" because there are really only 4 steps in the order of operations. Every year I have to reteach this because students always want to think that there are 6 steps-do all the multiplication and then go back and do all the division and then the same for add and subtract. I use the saying "Grandma Eats More Apples."

Do you know GERMDAS? It incorporates radicals at the exponent level (since they're just fractional exponents)
