This is what I do. I usually get the yellow poly 3 prong folders, but they can get expensive, so I decided this year to get regular one cent folders from Staples. I got two sets so in January the kids will get new folders. They wont be as nice as the poly folders, but they'll be cheaper! I print on shipping labels "B.E.E. Book - Bring Everything Everyday!" with cute bee clip art and stick it on the front. On the inside I have address labels that say LEFT at home and Bring RIGHT back on the pockets with hand print clip art. Then in the prongs I put a sheet protector. At the beginning of the year in first grade it held a page with an alphabet chart and then a little later in the year a sheet with all our word wall words. I wonder if gluing a ziplock bag to the inside of the "bring right back" side of a pocket folder would work instead of having a pencil case. I wonder if all that makes sense!
