If you have a child or teen who needs a little reminder of PEMDAS from his Dear Aunt Sally, I have some links to free order of operations posters and cheat sheets that you can use.
These freebies print on 8 1/2″ x 11″ paper and can be hung up on bulletin boards, walls, or doors. Some are color and some are black and white. Use them until your math learner becomes confident with the order of operations and then take them down.
Order of Operations Posters
Sanchez Class: This is a link to a PDF poster of my dear Aunt Sally and her tips for doing order of operations.
Math Equals Love: Make your own PEMDAS and GEMDAS posters with the printables on this site.
Go Teach This: There is a Order of Operations Poster that costs $0 on this site.
Peoria Public Schools: This is a link to a 64-page math cheat sheet printable that has the order of operations on pages 16 and 17.
I hope these order of operations posters and cheat sheets helped your math learner. If you know of anyone else who could use this list of freebies, please, encourage them to join the Membership Area here.
