This year I am going to have my students keep a composition book for their warm-ups, and I would like to have them keep them in class so they are available when needed. I have a bookshelf already I plan on using. What would be a good way to organize the notebooks so students can find theirs easily? I already plan on having a specific place for each class. I don't want this to add any lost time to the beginning of class as students struggle to find theirs in the class's stack. I had one idea... Maybe letting them choose a unique decoration for the spine of the notebook? Like a sticker or something along those lines. Has anyone tried something similar? It's just a silly little thing to worry about, but I have shorter class periods so I feel like every minute is important.
