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! We are in the process of tentatively scheduling our fall meetings, and 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. Right now we are planning to have the September and October meetings outside, but we will move them online as the situation warrants. Know that we have your health in mind.


The game of Sprouts! Saturday September 12, 10AM-Noon, Pullen Park, Raleigh. With Dr. Kim Johnson.

What: a free workshop exploring the game of Sprouts.
Where: Pullen Park, Shelter 3 (at the top of the hill)—OUTSIDE.
When: Saturday September 12, 10AM-Noon
Who: Math teachers of all kinds: pre-service, K-12, university, retired, tutors, homeschool, and other interested parties.

Join us for a free socially distant workshop! We will start by playing the game of Sprouts and then analyze how the mathematics of the game works. Can you find a winning strategy? Can you predict who will win? Teachers will leave with a Desmos activity they can use with their students, as well as a chance to win prizes.  We will meet outside and follow all social distancing protocols.

We will be right next to the upper parking lot: Enter from Ashe Avenue, continue past the aquatic center, and parking will be on your right and left.  Make sure to check the website for updates to time and place. https://raleighnc.gov/places/pullen-park

Ranked Choice Voting. Saturday October 17, 10AM-Noon, Piney Woods Park, Durham.

What: A free workshop on Ranked Choice Voting. Led by Dr. Linda Green, UNC-Chapel Hill.
When: Saturday October 16, 10AM-12
Where: Piney Wood Park picnic shelter, Durham—OUTSIDE.
Who: Math teachers of all kinds: pre-service, K-12, university, retired, tutors, homeschool, and other interested parties.

Have you ever wondered whether the way we choose our elected officials is the best way? And what the other ways are?  We will talk about an alternative way to vote, Ranked Choice Voting, and its benefits and any pitfalls.  We will sample some Locopops and vote on our favorite flavors.  Teachers will leave with ideas for introducing different voting methods to their students.

We will be at the picnic shelter at Piney Wood Park in Durham, near the intersection of Fayetteville Rd. and I-40 just off of Woodcroft Parkway. https://www.dprplaymore.org/Facilities/Facility/Details/Piney-Wood-Park-56

Mathematical Modeling and Pooled Blood Testing, Saturday November 7, 10-11:30AM, Online!

What: A free online workshop about Pooled Blood Testing. Led by Maria Hernandez, recently at the North Carolina School for Science and Mathematics
When: November 7, 10-11:30 AM.
Where: Online Zoom meeting, more information to come!

Suppose you have 1000 samples given for testing a community for drug use or for Covid-19.  You could test them all individually, but that would be expensive.  So you decide to test them in pools.  How big should the pools be? How many tests do you expect to do?  These questions can be explored using techniques of math modeling. Teachers will leave with resources they can use for math modeling.

Register HERE: https://bit.ly/TMTCPooledTesting . Please register so that we know you are coming to the Zoom meeting and so that we can update you about any changes.


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!
