Good Morning America

I was on Good Morning America yesterday, one third of a segment called “The Art of Beating Long Lines.”

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. So what we should be doing, as math educators, is teaching our kids how the math applies in situations like this, so shows like Good Morning America can report on even bigger and better things. I thought the piece was interesting, but unnecessary to anyone who already understands these ideas. If we can help create a culture of people who can use math, maybe it’ll stop being this mysterious thing that only dorks can figure out.

  2. Yeah, and my pick. Here, I was assigned a line — the one right next to the express line — which isn’t exactly how it works under normal conditions but I didn’t feel like protesting the scientific rigor of a cute weekend puff piece.

  3. Congrats. Puff piece or not, great to see your work being valued and underlying something far beyond the classroom.


    Not sure of the math, but it strikes me that you might be the first edu-blogger break-out star.

    First Google, then “GMA”. Just a matter of time before you grab a 7-fig Twitter-inspired sitcom deal.

    Then TMZ followin’ you every where.


    P.S. Will there be a special Dan-on-location-at-the-mall Christmas rush follow-up special?

    If so, I’m willing to come write some holiday haikus in the lane next to you if it’ll add some additional value to the segment.

  4. I know it was a puff piece, but I still thought it was great to see math in everyday situations. BTW, you are WAY tall!! She looks like she represents the lollipop kids standing next to you.

  5. Although I rarely come by here any more, and I never watch GMA, I saw that show and knew immediately that it was you. I told my husband, who was watching, that I had read your blog, that you had photographed the arched bridge at Mount Hermon and that you are very, very smart. Good piece.
