Use these teacher-recommended mathematical gems at random moments in your classroom.

Here’s a collection of videos recommended by colleagues across the globe.

Some pieces are short and make for excellent classroom starters. Some are longer for the odd ten- or fifteen- moments of class time. Some are longer still for full class activity.

#### DAY 7 OF GLOBAL MATH WEEK: A Square Root of Two cartoon from BEN ORLIN (introduced by James).

The inimitable Ben Orlin selected this gem of a cartoon for us to share for Global Math Week. He had this to say about it : “Irrational numbers are bottomlessly weird. Sometimes I think I’ve gotten used to their strangeness, and I like it when a thought experiment like this one (delivering mail to the square root of 2) can shake me out of my complacency and remind me again of how unfathomable they are.”
