I use 3 prong plastic folders as homework folders. I make a big deal at the beginning of the year about how "expensive" they are and make the kiddos promise they will take great care of them. The majority of the kid had the same folder at the end of the year (looking very worn). I use labels to label each pocket and a plastic sleeve for the monthly calendar which is used to record math homework. Click on the pictures to get a copy of each.
