I have found that many students show up to my high school math class without something to write with. I have found that teachers use different methods in dealing with this situation. Some teachers sells students a writing utensil, while others take collateral to use one of theirs, some teachers just let the kids sit there if another student does not have a utensil that can be borrowed. I am not sure how to deal with this appropriately. I find that trying to track down my pencils by the end of the period that were borrowed when you are teaching bell to bell can be difficult. Any suggestions?
