|The pencil holder (the sides are magnetic).|
This pencil cycle has worked it's way into my expectations - I don't get concerned when all of the pencils disappear, because I know that eventually my stock will be replenished. The highest record for adopted pencils was 6 living in the pencil holder, at the moment we are on 3. A new addition was found on the floor this morning. I haven't had to buy a single pencil this year so far.
We do find the occasional eraser, but that is much rarer. There is a general catch-all lost property box that houses the miscellaneous items that are left here. I'm not a monster, if a stationary item has a name then we return it. The only other item that is left behind as much as pencils is homework diaries. The homework diaries are used by my young students to record their logins and passwords for our educational websites - they leave them behind often just out of sheer forgetfulness when being fetched by parents in a rush.
