- In July 2018 Tyler Erb of
Community House Middle and I will team up to offer two identical
one week courses, one July 9 to 13 and the other July 16 to 20, for
middle school students. I call the course Exotic Arithmetic.
It includes weird
bases, binomial coefficients, Catalan numbers
and place value problems. The course is aimed at talented students. The
cost of the course is $300. Each session is limited to 10 students. The
courses will meet at the Earthfare store, 12235 N Community House Rd,
Charlotte, NC from 9 to noon each weekday.
In July 2017 my problem
book with Y Z Zou and Jon Kane was published at World Publishing
Cooperation (Beijing) .
Mathematical Contests, A Guide to Success,
is designed for use by both American and Chinese
high school students. It consists of six parts
in four volumes, Basic Knowledge, Essays, Practice Problems, Past
Contest Problems (including MATHCOUNTS, ARML, Purple Comet, AMC8,
AMC10, AMC12, AIME, and several others. Here's a video
intro to the book. The KendallHunt version for the US and Europe is
ready. It's 720 pages, sells for $60 (8 cents per page, roughly). Order
it at KH.
- Math 1120, Business Calculus
In the fall of 2018 I am teaching sections 003 (at 10:10-11:00 MWF) and
(at 4:00-5:15 MW), in Fretwell 206 and Friday 142 respectively.

pleased to be invited to conduct a Family Friday session at the Museum
of Mathematics. The topic is Chameleon
Cubes. In addition, I presented Fusing Dots at the
Island Math Citrcle on Saturday, Oct. 8. I
am pleased to announce that during the spring semester 2017 I will be
working with the Talent Development office of the Charlotte Mecklenburg
Schools. In January 2017 I was asked to write four blogs for the
National Council of Teachers of Mathematics. The format is somewhat
restrictive so the originals had to be reduced in size. Here are the
four originals, Area

gig with the Tulsa Teachers Circle in June followed by a week of work
at my daughter's camp Play Math at Michigan State. I also plan to work
at Epsilon-China at Eurasia
University in Xi'an, China, July 29 to August 15.

occasions. Here's the link to the September 2011
seminar on KenKen. In April 2013 I conducted
Intermediate KenKen for DYS. I've posted the files we used in the same
place. I'm looking forward to hosting another seminar in Janaury, 2015
on KenKen and Modular Arithmetic.

them closely tied to the Common Core State Standards.
the UNCC contest problems are included. And it is
free. Also, I wholeheartedly recommend the new AMC Advantage at Edfinity.com. Its
designed to help AMC 10 and 12 students diagnose their weaker areas and
provide exercises to overcome those weaknesses.
October 11, 2012 I was presented the North Carolina Board of Governors'
Award for Public Service at the Board of Governors' meeting in Chapel
Hill. My remarks can be found here.

university held a reception on January 16. Here

Ahlin and I have agreed to co-edit the problems section of The Pi Mu Epsilon journal. In
November 2012, I had the great pleasure of learning about three of my
problem editor-predecessors, Murray
Dodge. All three are legends in the history of
mathematical problem solving. Here is an article
written by Leon Bankoff about editing problems, teaching ,
and learning mathematics. Your

wonderful woman Betty
proud that at the age of 56 she was awarded a PhD from the University
of South Carolina. She is retired now after a successful career
teaching mathematics and computer science at UNC Charlotte, Winthrop
University, University of Hawaii, Davidson College and Central Piedmont
Community College. Betty also taught at Clemson University and Richmond
College (London) during the years we spent in those places.
also proud of Betty's and my daughter Ashley Reiter
