Every year I need a refresher on synthetic division. I don't know what it is about the method, but for the life of me I can never remember what goes where and what to do next. Once I see it, it's so simple (facepalm), but by the time the topic comes up the next year, I definitely need that refresher.
Today I made a cheat sheet to give to our students tomorrow as we get ready for a polynomials quiz on Thursday and mid-year review next week. Really, the sheet is as much for me as it is for them:) It's a half-sheet so I papercut the sheet in half and hole punch for the kids to put in their notebooks. You can download it from the "Freebies!" section of the sidebar if your kids need a reminder too!
I also recently made a reference sheet for graphing rational functions that you can download for free here.
