I'm Dan and this is my blog. I'm a former high school math teacher and current head of teaching at Desmos. He / him. More here.


  1. Thanks for pointing him out. I’m loving what he has to say.

    Also greatly enjoyed all your posts from the conference. I teach elementary school but I’m amazed at what I can take away from reading your blog.

  2. Thanks again, Dan. Although I think if you’d actually seen the calc lesson you might have tempered your use of the term “showing off.”

    It was fun, but MAN was I nervous!!
