I found this great organizing tip on Pinterst - Teacher know best!!! I have already done one like this for my READ 180 documents - now to get the rest of the room done!!
Don't waste time sifting through piles of worksheets - save yourself the
headache and create a “master book,” a tool that organizes all your
papers and keeps them all in one place. Tackle your mound of papers by
sorting through each one, tossing what you don't need and keeping one
copy of every important worksheet. Place them in a 3-ring binder with
dividers for each month.
