These are links to what is called "mini-offices". We like to use them especially because we have no wall space to hang posters!
I plan on making a few this year for ds. Of course some of the examples here are for much younger children but the concept is the same. Pasting info needed throughout the school day on folders to have right in front of the student for easy access. I think in public school they use them for privacy too, but we don't need that in our homeschool.
When I get one made I'll add a photo here.
