Classroom Teacher

I've been a full-time classroom teacher since 2007. I currently teach Math and Mathematical Art at John Burroughs School. I also run the JBS Math Circle, which meets irregularly to explore all aspects of the mathematical world from puzzles and riddles to art and mathematical games.

Previously I worked at Saint Ann's School in Brooklyn, where I was lucky enough to offer a number of original math courses like "Algebra 2: Functions and Abstract Algebra" and electives such as "The Complex Plane."

Also while at Saint Ann's, I cofounded a mathematical art program for grades 3-12 which included a high school seminar, a middle school elective, and an all-school mathematical art festival called MArTH Madness.

I was very fortunate to work in a wonderful department full of brilliant mathematicians, teachers, and artists, including Paul Lockhart, and my Math Munch coauthors, Justin Lanier and Anna Weltman.

Math Blogger

For many years, I've coauthored Math Munch, a site where anyone can find a curious and enticing thread to follow out into the mathematical internet.

For a couple of years I wrote a blog about math and school, called Lost in Recursion.  For the time being it can still be seen.

Independent Educator

In 2014, I founded Art of Math STL, so that I could share mathematics with kids outside of the math classroom.  In addition to private sessions, I run a math circle for 3rd and 4th graders at Reed Elementary.

For a while I taught classes at the very cool Brooklyn Brainery, and I sometimes dream of starting something like that in St. Louis.
