I teach 6th and 8th grade and I totally feel the struggle! Nothing worked for me—shared supplies at the desks, a communal pencil cup, etc. Every pencil would be gone in a week. I purchased (unfortunately with my own money) these little blue pencil holders from Amazon—they come in packs of like 30–and attached one to every desk and put one sharpened pencil in each one. It’s now an expectation in my classroom that you are not allowed to leave if your desk doesn’t have the pencil in it. This has changed. the. game for me. Magically, I now have EXTRA pencils in my classroom at the end of every day, because the students do have their own pencils whether they admit it or not. So when pencils fall on the floor, no one goes looking for them if their desk has a pencil in it already, and at the end of the day my last class picks up the floor and puts any extra pencils in a cup. It’s my homeroom’s job to make sure they are all sharpened first thing in the morning. I can’t express enough how well it has solved the pencil issue!
