A few details: We are also participating the ine larger workshop run by AIM. See their website for information.

What we are all about

The Chicago Math Teachers' Circle is intended to be an opportunity for math teachers to gather and solve problems together. Teachers of all grade levels are welcome. We are part of the national Math Teachers' Circle Network and share their goals and philosophy.

Our goal is to help teachers with the extremely difficult task of developing their students problem solving skills. But we do not focus too directly on what will be done in the classroom. Instead we simply give teachers the chance to solve interesting problems together. After all, how can you teach a skill that you don't practice? And besides, solving problems is great fun! If this sounds like something you would be interested in, please email "chicagomathteacherscircle@gmail.com" for more information. You can also take a look at this article in the math teachers circle magazine discussing what we do.
