This week’s Friday Fave is
There are many versions, and we recently upgraded them to include our Classroom Conversations tools.
Polygraph is a game in which one partner selects a mathematical object, and the other asks yes/no questions in an effort to narrow the selections down to the first partner’s selection.
It’s a fabulous way to start your school year, or your next unit. Draw out student ideas before there is an expectation of specialized vocabulary, and in doing so, you’ll create the need for that vocabulary in the lessons to come.
Advanced algebra, college algebra, and precalculus students will be challenged by Polygraph: Rational Functions (and so will their teachers, for that matter!)
In the Fave’s experience, the majority of Polygraph sessions result in the teacher gaining new insights into their students’ mathematical minds. And that’s pretty high on the list of priorities at the beginning of the school year!
So go play Polygraph with your students. We’ll see you next Friday.
