Make Your Own[edit]

It's amazing how much some of the suppliers charge for dot game paper. I don't know about you, but I think that 66¢ for a sheet of paper that's going to be used for one math problem is a bit high. Just print your own from one of the PDFs below. You could even laminate a sheet and use it with dry erase markers.
