Math Links for Week Ending July 14th, 2017

I have liked @Desmos' Polygraph from the get go. So it seems odd that it has taken so long for someone to take it offline. In this case it is @Mr_Stadel who has come up with a nice hack to do them online. And all it requires is some plastic sleeves and whiteboard markers. He's done Lines and Parabolas so far. Why not add your own?

More tips from @Mr_Stadel on using Polygraphs in class. This time it's using the idea of a word bank to help students (and a list of "taboo" words that students cannot use). The idea is to help students use more academic language while using Polygraphs.

And Finally from @Mr_Stadel's quest to maximize the use of Polygraph, he introduces the idea of a PolyGraph "Word Jar". Watch the video below and then follow the link for more info on how to use it.
