Anything With a Slick Surface Can Be a "Whiteboard"

One thing I have used in my classroom before is the clear paper protectors. Just slide in a sheet of white cardstock. You could put in a binder and even print out games like tic tac toe or bingo on the cardstock. Black dry erase markers wipe off best-sometimes red and green especially leave residue. An old dish towel works well to wipe them off. Don't leave dry erase marker on for too long or it is hard to clean off.

I like this idea, I play a lot of Sudoku and I can use the same book over and over again. Thanks.
