The East Texas Math Teachers’ Circle provides teachers and math enthusiasts with opportunities to explore rich, open-ended mathematical questions as they develop and discuss problem-solving skills. This program is partially funded by the American Institute of Mathematics. Events are free and professional development (CPE and G/T) credits are available. For more information, contact Dr. Jane Long at

Schedule for fall 2021 and spring 2022

Remaining meeting topics and speakers TBA

Tuesday, September 21, 5:30 to 8:00 p.m.

Facilitator: Dr. Brittney Falahola

Title: "The Jug Band"

Description: "Using just a 5 pint jug and a 12 pint jub, measure 1 pint of water!" Is this possible with just these two jugs? What about a 7 pint jug and a 17 pint jug? Or a "p" pint jug and a "q" pint jug? Join us to investigate these questions together.

Tuesday, October 19, 5:30 to 8:00 p.m.

Facilitator: Dr. Nicholas Long

Facilitator: Dr. Clint Richardson

Tuesday, May 17, 5:30 to 8:00 p.m.

Our Math Teachers' Circle will hold hybrid meetings during the fall 2021 semester. You may opt to attend in person at the SFASU campus or online through Zoom. Dinner will be provided, at no cost, to face-to-face participants.

Please complete this form to register for meetings. You may register for one or more meetings, and you may return to fill out the form for another date at a later time. So that we may plan appropriately, we will send follow-up email communication a few days before each event. At that time, we will ask whether you plan to attend in-person or virtually. Meeting details such as parking and information on joining the virtual meeting will be shared at that time.

Spring 2022 registration will open in December 2021.

For more information, please contact Dr. Jane Long at

Feb. 9: "The Tower of Hanoi"
Led by: Dr. Brian Beavers

The Tower of Hanoi may seem like a simple mathematical puzzle, but it has many surprising connections. Studying its solution lets us revisit many common mathematical problem-solving techniques and old friends like Pascal’s triangle and Sierpinski’s gasket. We’ll look below the surface and find something for students of all levels!

March 16: CANCELED
Led by: Dr. Clint Richardson


April 13: "Looking at Functions and Graphs"
Led by: Dr. Tom Judson

What is the graph of a perfect golf shot? How do we plot graphs from pictures, words or tables? We will investigate some of these issues using materials from Shell Centre for Mathematical Education.

May 18: "Magic Squares"
Led by: Dr. Brittney Falahola

Around for over 2000 years, “magic squares” have been thought to have mystical properties – even helping astrologers in the 9th century determine horoscopes. But what is so special about a square filled with numbers? Come join our discussion to find out! (No background knowledge needed.)
