Dear Math Circle Friends,

We are excited to invite you to our March meeting facilitated by our very own TMTC member, Rich Redner.  With a topic of KENKEN puzzles, we have a fun, fun evening in store for all!!   Please join us at 6:00 pm for dinner, immediately followed by our problem solving session.  As always, there is no charge and you are invited to bring a colleague! 

Date:               Thursday, March 2
Time:               6:00 - 8:00 P.M.
Place:             The University of Tulsa, Keplinger Hall, Room 3160 (Upstairs on west wing of building)
Facilitator:     Rich Redner, TU Math Faculty and TMTC member
Title:               CAN you KENKEN?

Bio: Rich Redner earned a bachelor’s degree in math and physics from Guilford College in 1974. He was awarded a master’s in 1976 and a Ph.D. degree in 1977, both from the University of Houston.  After completing his degree, Rich Redner spent two years at the Johnson Space Center as a National Research Council Associate performing research in pattern recognition applied to remote sensing. 

Dr. Redner has been at The University of Tulsa since 1980 and is currently Professor of Mathematics and Associate Dean of Research and Graduate Studies.  He notes that the job of Associate Dean is a great job. He gets to admit master’s and doctoral students and graduate them.  He also gets to award research funding and with teaching and research assistantships. The assistantships help fund their graduate degrees and give them experience in their field.
He enjoys reading science fiction, fantasy and a good vampire story from time to time.  He fought his first judo match at the age of 35 and played judo for 15 years.  He retired with the rank of Yondan, which is a fourth degree black belt.  Now he enjoys walking and has a daily goal of walking 10,000 steps a day.  He lives with his wife of 45 years in Tulsa, Oklahoma.

TMTC Meetings 2016-2017 Academic Year


The Tulsa Math Teachers' Circle usually meets on the first Thursday of selected months during the school year. After a light meal, a topic in mathematics is explored through problem solving and discovery. TMTC is beginning its fourth year, building upon the successful past years' programs and summer immersion workshopos. Mathematics Educators and Professionals at all levels are wlecome and encouraged to attend. There is no cost to you, so come and enjoy!



The mission of the national Math Teachers’ Circle (MTC) program, developed at the American Institute of Mathematics (AIM), is to establish the foundation for a culture of problem solving among middle school math teachers in the U.S. By fostering the confidence to tackle open-ended math problems, middle school teachers become better equipped to initiate more student-centered, inquiry-based pedagogies in their classrooms.


“Math Circles are a form of education outreach and enrichment through which mathematicians and mathematical scientists share their passion with K-12 teachers and students. The Math Circle landscape includes two types of programs that can operate standing alone or in coordination: Math Students’ Circles and Math Teachers’ Circles. Math Circles bring K-12 students or K-12 mathematics teachers together with mathematically sophisticated leaders in an informal setting, to work on interesting problems or topics in mathematics. The Math Circles combine significant content with a setting that encourages a sense of discovery and excitement about mathematics through problem solving and interactive exploration. Ideal problems are low-threshold, high-ceiling; they offer a variety of entry points and can be approached with minimal mathematical background, but lead to deep mathematical concepts and can be connected to advanced mathematics.”

TMTC was the first math circle in Oklahoma with its inception in October, 2013.  TMTC now averages 35 teachers at monthly evening meetings on a school night.  TGMC, the first girls’ math circle in Oklahoma, is now in its third year and averages 25 middle school girls on weekly evening meetings that run for six week stretches three times per year. Math Circles are thriving in Tulsa!


The Tulsa Math Teachers’ Circle hosted its’ inaugural meeting in October, 2013.
The program was formed:

  1. To engage middle school math teachers in mathematical problem solving and involve them in an ongoing dialogue about math with students, colleagues, and professional mathematicians; and

  2. To provide guidance, materials, and resources to middle school math teachers that will enable them to promote open-ended problem solving as a way of learning, thinking about, and practicing mathematics in their classrooms.
