I have always disliked filing cabinets, because the papers never stay straight, the folders break, and it just feels so unorganized. I came across this idea shared on Pinterest and decided to make some for myself (my classroom theme). This is an editable resource, so you may use whatever subjects/units you decide.
I have included a few:
Back To School
Heredity & Development
Side labels for easy location when on a book shelf.
Fonts Needed: Beyond the Mountains, Lego House
