The Triangle Math Teachers’ Circle welcomes anybody interested in the teaching profession, at any level, with an interest in learning and practicing the pedagogical approaches of math circles aimed at the development of creative problem-solving skills through interactive and fun activities. Join our mailing list here.

 The initiative is hosted by the Department of Mathematics at North Carolina State University and is supported by a grant from the American Institute of Mathematics. The Teachers’ circle collaborates with the Chapel Hill Math Circle for K-12 students and is a member organization of the Math Teachers’ Circle Network and the North Carolina Network of Math Teachers’ Circles.

Math Teachers! In scheduling our fall meetings we are excited to experience the joy of discovering mathematics together this year! Please know that we will follow all state and national guidelines for social distancing. We will have some meetings online and some meetings outside as the evolving situation warrants. Know that we have your health in mind!

The birth of non-Euclidean Geometry

Online: Saturday January 23, 3-4:30, via zoom.

I have traversed this bottomless night, which extinguished all light
and joy of my life. I entreat you, leave the science of parallel
alone”, wrote a Hungarian mathematician Farkas Bolyai to his son
János, horrified at the thought that his son is attracted by the
problem of parallels. János was not deterred, however, and discovered,
simultaneously with Lobachevski, a consistent geometry in which the
Euclidean parallel postulate does not hold. We will zoom through the
path of mathematical thought that took over 2000 years, noticing which
results from a high school geometry text-book do not rely on the
parallel postulate, and which are altered completely in hyperbolic
geometry. No background beyond K-12 geometry is required (and do not
worry if it is not fresh in your mind). We will so some hands-on
experiments with free software:

Chameleon Island

Online: Saturday February, 3-4:30, via zoom.

What: A free online workshop playing with Chameleon Island
When: February 20, 3-4:30 PM.
Where: Online Zoom meeting, more information to come!

The Julia Robinson Math Festival folks are coming to lead a workshop on Chameleon Island for our group! Expect lots of fun puzzles and interesting mathematics, a way to rekindle joy in discovering and playing with mathematics. There will also be ideas about how to lead your students in discovering mathematics, along with the web application: https://www.jrmf.org/digitalapps/chameleon-island

Get more information about what the Julia Robinson Math Festival is doing in this time of no festivals: they have weekly webinars, training, and social events. https://www.jrmf.org/

The national Math Teachers’ Circle Network workshop is over, but you can still see the workshops!

The week of July 13 to 17 the Math Teachers’ Circle Network held a week of online free workshops for teachers. The theme was the joy of mathematical discovery, and we played with math with James Tanton, Maria Droujkova, Scott Kim, Joshua Zucker and others. Find the videos of the workshop here!

Enjoy Math, while staying at home!

Unfortunately our planned Spring 2020 meetings had to be put on hold due to COVID 19 pandemic. We wish you all to stay healthy and well during these difficult times. We hope that these free online resourses from AIM Math Communities will help you continue enjoying and learning mathematics. Take care!
