This book American 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.
- Math 1120, Business Calculus
In the fall of 2017 I am teaching sections 004 (at 12:30 MWF) and 002
(at 3:30-4:45 MW), in Fretwell 128 and Fretwell 124 respectively. To get directly to canvas, click here. Two other websites I recommend for students in
this course are listed below. In case you're having trouble,
example, with the Chain Rule or max-min problems, watch a video at Kahn Academy
at no cost. Also, try JMT's utube.
Furthermore, I recommend Education
Portal which has lots of videos. One
of the best online books is Herb Gross' Calculus
in Everyday Life. It is available at no

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
thrilled to be invited to visit Sichuan University in Chengdu, China
from Oct. 8 until Oct 18, 2016. I enjoyed working with high school and
undergraduate math students and my host Dr.
I visited Dr. Zou again in Julne and July, 2016. We are very nearly
finished writing American

which we hope will be available in July 2017.

Academic Center is especially memorible. The list of activities we
discussed is here.

proud and excited to have worked during the summer of 2010 at the
Academy for Mathematics, Science, Arts and Technology, AMSAT,
in Bangalore, India and I hope to do it again.
enjoyed conducting seminars for the Davidson Institute
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.
- In the summer of 2017 I worked with Isil Nal at Momentum Learning
during the second and third weeks of June. The topics include
Combinatorics and Number Theory. Then I worked with my
daughter Ashley Ahlin at her summer camp Play Math teaching a course called Exotic Arithmetic. Then in late July I worked at MathPath and once again at Epsilon Camp. For parents of 8 to 12 year olds, I hope you will also check out the new CAMP&! in Arkansas.
excited to report a new website for problems. Problem-Attic
has 80,000 questions for students in grades 3 through 12, many of
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.

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
Klamkin, Leon Bankoff,
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

I'm married to a
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
Ahlin who received her PhD. at University of Chicago in
working in the area of Geometric Algebra. She lives in East Lansing,
Michigan where her husband Chris
