I just stumbled upon Cool Stuff for Nerdy Teachers.
(They had me at “nerdy.”)
You can find some very cool, free PDF versions of charts, visuals, posters, organizers, and strategies for your classroom.
If you don’t have time to make these kinds of things (who does?) or you don’t believe in reinventing the wheel, look here first.
The only thing you’ll need is color ink for your printer and it’s recommended you laminate these 8 1/2 x 11 pages.
It looks like you can also purchase an editable format for $10 if you’d like to tweak it.
The posters are colorful, visually pleasing, cover the K-12 spectrum in many subject areas, and, for me….give me great ideas of things I’d like to make!
