This is my graph template that I use for Calendar Math. I put cloth on the wall to make a makeshift bulletin board and then use masking tape to make the grid. This is a quick and easy way to turn any bulletin board into a large graph. I usually take a picture of the graph. At the end of the year, it is fun to see the variety of graphs we’ve made.
One day when I have a magnetic board, I will turn that into a large graph by adding colored tape for the grid.
