Make Your Own Whiteboard Tables. In the spring of 2015 I received brand new square tables for my classroom and turned the tops into whiteboard tables. It was a game-changer that I stole from Reuben Hoffman. Early iteration of my 10 tables. 8221; questions from students. That can be cut to size.

Earlier this week, as part of a larger workshop on mathematics and technology, I gave an introduction to Twitter as a digital collaboration playground for educators.

Teaching, math, teaching math. The first was this ignite talk. On mathematical structure that has helped me to learn an enormous amount about that practice standard, and have continued working on since then. The second interesting moment happened after PCMI.

I dropped everything and moved to New York to teach Math. I already mentioned it in my blog post from TMC15 Friday. So I wrote to Lisa Henry.
