A handmade set


One of my favorite mathematical minds (nickname: the Vegan Math Pup, daughter of the Vegan Math Beagle) was inspired to make her own Which One Doesn’t Belong? set.

As a teacher, I am most rewarded when I see evidence that I have helped to shape the way students see the world. This is much more rewarding to me than mastery of procedures, or recall of facts. New lenses on the world tend to stay with us longer, and have more subtle but deeper and longer-term impact.

When a five-year old spontaneously starts drawing sets of shape with contrasting characteristics, I know I’ve gotten into her head. (And she into mine, if we’re being totally honest…I documented her precise work on the definition of a sandwich a couple years back.)
