Math Links for Week Ending Oct. 11th, 2019

Featured Links
Hey, it's Global Math Week. That means it's time to get your kids to explode some dots. You still have time to get your class hooked up. The great thing about exploding dots is that it is appropriate all age groups. It's got a low floor and the math can go way into grade 12 polynomials. Check out the intro video from @JamesTanton and then sign up your class at the Exploding Dots website below.

Opinion Links
As someone who has provided PD for teachers for many years I totally know that sometimes that PD falls flat. And everyone has an opinion on what PD they don't like but often don't have ideas about how to make it better. In this post @MarkChubb3 has some insight about what good PD could look like.

This kind of math floors me. Just when I think I have a sense of the magnitude of 1 billion, something like this comes along and blows me away. pic.twitter.com/m7hJmSPjrM
