Halloween Math and Other Tricks and Treats
Halloween seems to get bigger every year. While I’m saddened to see the free-range trick-or-treating of my childhood wane, I still love the imagination with which so many young people (and their parents!) embrace the season.

Listening, Math, and Mathematical Questions

NRICH: Welcome to the Home of Rich Mathematics!

One of my students sent me the website for NRICH—the home of rich mathematics and I was hooked. NRICH is associated with the University of Cambridge and … Continue reading
Hamilton, Schoolhouse Rock, What’s Next?
This week I saw two very different musicals. Well, to be honest, I saw all of one and parts of another. I was one of millions who have had the opportunity to see the PBS documentary on Hamilton, the Broadway smash musical that combines hip hop and history to tell the story of Alexander Hamilton, … Continue reading
It’s October: Time for Creative Spookiness!
Every year I tell myself I’m going to post spooky October suggestions in time for teachers to actually use them–and this year, finally, I’m going to do it.
