This year, I've decided to designate a separate crate for each class period. These crates are for students to store their notebooks in (if they wish). And, each student has a file folder to hold graded work.
This is building off of last year's organization system. Last year, each prep (Alg 1, Alg 2, and Trig) had a file cabinet drawer to store notebooks in. Graded papers were stored in 3 crates. This worked fine, but I decided I wanted to reclaim my file cabinet for my own storage!
Having a separate crate for each period makes it easier and faster for students to find their notebooks!
I printed the labels two to a page, laminated them, and cut them in half.
I've uploaded the files here in case you want to make your own crate labels. For the editable Publisher file, you'll need to download this font: HVD Comic Serif Pro.
