I love these write and wipe pockets I purchase recently. They are plastic pockets that you can insert worksheets in. You can write on the pockets using the provided dry erase markers. There's even a holder for the marker attached. I used to use heavy duty sheet protectors for this type of work but find these so much better. These pockets come in handy for those worksheets that I foresee my student having to do more than once. It saves me paper and time!
