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. more EW? seriously, someone of your intellectual acumen should read something a bit more esoteric.

    find a way to intergate EW in a lesson and, well, then you’ve got something.

  2. my kid is a t.a.. does that stand for teacher’s assistant or is it some new spelling of indentured servant?
    about the only thing she hasn’t asked him to do, yet, is wash her car

  3. I sent my TA a to-do list. It consisted of a link to this post. His response? “Haha”.

    Heavy sigh, how do you inspire that level of dedication? And in the rain, no less. I have so much to learn.
