In the fall of 2015 I am teaching sections 3 (at 11:00 MWF) and 5 (at 2:00 MWF),
both in Fretwell 128. 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 cost.
thrilled to be invited to lecture
and talk with students and teachers in Bogor, Indonesia in April 2014.

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. In
2014, I worked at MathWorks

RL Moore Legacy conference in Denver, CO. entitled Teaching
PIE to Ten Year Olds. I also recommend MathPath,
and Awesome Math.
might be helpful to parents seeking more information. PROMYS for teachers
is another program I highly recommend. There is also a program for
budding computer scientists run by Wolfram. I do not know much about Mathematica Summer Camp,
but it looks interesting. Also, I'd like my readers to know about a new
venture called Proof
School in San Francisco.
In November 2014 I enjoyed spending a week on the Navajo Nation working
with Navajo children and teachers.
In September 2014 I was
given the opportunity to welcome the delegates to the CCSS Math Summit sponsored by NC Ready for Success.
My remarks are here.
the summer of 2015 I plan to work at Punahou
School in Honolulu from June 15 to July 17, and then at Epsilon Camp at
Washington University in St Louis from July 26 until August 9.
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.
- I'm happy yo report that I have just started in April 2015 to lead my second Charlotte Teacher Institute seminar in Fundamental Mathematics.
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.

- My daughter Ashley
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 Baker Reiter. I'm
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
is a professor of Economics at Michigan State University. I
