Friday Fave for February 15

The Friday Fave loves words.

The best words are the ones that mean exactly what you want to say.

And Polygraph is one of the best tools the Fave knows for helping students develop things that they want to say about mathematical objects such as parabolas, functions, and hexagons.

This week, Twitter gave us glimpses into two classrooms where students were developing things to say that they’ll soon have words to express. Press “Play” to witness the sights and joyful sounds of the early stages of math vocabulary development.

Polygraph comes in many flavors, including algebra, geometry, and even numbers. In each case, Polygraph builds a context for powerful mathematical words, which is what makes it this week’s Friday Fave.
