Key Graphing is owned and operated by John and Sandee Key. Sandee is a Mathematics teacher who needed an easier and less expensive way to graph. Therefore, she invented the Static Cling Grids. The business is located in Brown Summit, NC and has been in operation for three years. Key Graphing currently produces three different grids, the coordinate plane, the first quadrant, and the unit circle. Coming soon will be the new Static Cling Maps.
