Congratulations to the students I coach at Ligon Middle School on their second straight state MATHCOUNTS title.  Keep the trophy at Ligon!

MATHCOUNTS is the nation's premier middle school math competition.  Due to copyright restrictions, I can no longer post additional materials other than what is available on their site.  Below are links to materials provided on the MATHCOUNTS site, as well as lessons that are helpful preparation for the competition.

Ordering Materials is easy, and coaches starting programs can usually find funding.  If you are interested in starting a MATHCOUNTS program at your school (in North Carolina), there is usually funding available.  Contact John Goebel (goebel@ncssm.edu) for information about available funding for a MATHCOUNTS team at your school.

I was asked to remove my MATHCOUNTS materials from this site, but the Coaches Corner at Minnesota MATHCOUNTS has a ton of old competitions that can be used for practice.

Unfortunately, many (most) of the worksheets below do not have keys.  Because these are the materials I use to teach my classes, I do not post keys (and, because I don't have electronic keys made yet).  I hope to have a book finished by the end of summer which will include the majority of problems on this site with keys and some full solutions, along with more explanations on the math involved which often get left out of the worksheets and transparencies I produce (at which point I will need to start writing new problems for my students).

Ten Essential short practice sets for MATHCOUNTS:  Counting, Probability, Statistics (Mean, Median, Mode), Patterns, Pythagorean Theorem, Area, Three-Dimensional Geometry, Proportions/Ratios/Percents, Algebraic Equations, and Number Theory (Factoring).  Need answers?  These problems are tough!  The key is here.  Updated 12/31/2008

Number Theory:  Primes, Divisibility, Factoring, Factoring 'Tricks', Factorials, Different Bases, Units Digits.  (52 pages)  Updated January 28, 2009.

Draft Counting unit.  Mostly Completed now.  (42 pages) 
Updated 2/26/08.

Draft Probability unit.  Mostly complete, but could use some revisions.  Updated 4/26/09.

Number Sense Worksheets 1 2 3 4 5 6 7 8 9 10 as used by (4 time National MathCounts champion coach) Jeff Boyd's top flight math program in Texas.  Keys HERE.  Perhaps these are the reason why Bobby Shen knew LCM(14,15,16) before I read the question.

MathCounts Toolbox:  From MATHCOUNTS, this is a very good list of things that every student should know.

27 Problems and full solutions which illustrate a number of important tricks used in middle-grades math competitions by Keone Hon.

A nice practice set from Matthew Crawford, AoPS author and founder of Mist Academy who has helped train many of the country's best young math students.

Much more to come.  Visit here often as this is the page I will be working on most in the coming months.
