Pencils and pencil sharpening can be a source of noise, a source of wasting time as well as a frustration when a pencil cannot be found. I have put two boxes where students can get to them quickly. One is labeled "Borrow Box" and it is filled with sharpened old pencils or new. They are labeled with masking tape so we know they are borrowed. If a pencil is lost the students can quickly grab a sharpened pencil from the borrow box. The other box is labeled "Pencils for Sharpening". Students' unsharpened pencils will be sharpened at the end of the day by a person assigned to do so. Students can also use their reward money to buy a pencil from me for $1.00 (play money). This makes them want to be more responsbile for their pencil. I have found this to be rewarding in that no pencils are being sharpened during the day, not time is wasted, and it makes the student responsible for their "tools".
