When I was a kid, I was notorious for losing pencils (elementary school). I remember in 2nd grade, my mom would send a sealed envelope with pencils in it. The teacher would keep it in her desk and I would have to ask for a pencil at the start of the day and turn it back into her at the end of the day (we didn't' change classes in 2nd grade). When it got too dilapidated to use, etc, I got a new one. That poor teacher!!
