Starter Pack

Hi! This blog is over ten years old and has hosted 1,500 posts during its first ten years. Let me pull out some highlights.

I taught high school math for six years and shared much of my curriculum online. My most popular lessons included Graphing Stories, Stacking Cups, Will It Hit The Hoop?, and The Feltron Project. I created a style of real-world lesson plan called Three-Act Math, which a bunch of educators enjoy and a bunch of educators find totally weird. (The former group has a website clubhouse with 30,000 members.) I was very skeptical about the value of homework and I assessed students using a process that is known as Standards-Based Grading.

During my last year in the classroom, two events transformed my career. First, I was laid off from classroom teaching. Second, I gave a talk about math education that went online and has been viewed a couple of million times. (You can watch other talks I’ve given also.) Those events put me on a path to a) speak publicly about instructional change in math education in forty-nine states and four continents, and b) earn a doctorate studying with some of the best math education researchers around.

I now work for a math edtech startup called Desmos where we try to help students learn math and love learning math. I have opinions about math education technology, most of which are pessimistic, though occasionally I’m exuberant about its possibilities.
