  1. I just wanted to say thank you for all the content you’ve posted here. I have been using your materials to guide my geometry classroom this year and I love it. I have learned a lot from you and my students are thinking more this year than any year I have taught geometry prior! I appreciate your work.

    1. Wow thank you for the kind words, Alyssa! I really appreciate it! I’m very happy to hear that the site has been useful and your students are doing well. That’s great news!
