I taught math and physics in an Indiana public high school for twenty years. I created GraphFree because I couldn’t find any other graphing program that did everything I thought math teachers needed. I used it often in my own teaching, and I wanted other teachers to benefit as well.
Now I’m a stay-at-home dad for two adorable young children, but I still like to keep this project alive for other teachers. During the quarantitne of 2020, I’ve given the site a major upgrade to make it more user friendly and add a few new features. And to be honest, I’m hoping the effort does bring in a little more money for the family. I want to keep it free, but any voluntary support you provide is greatly appreciated.
If you have any questions about the site, feel free to e-mail me at:
