2008-2009 Contest Dates:

The AMC 8 is a 25 question, 40 minute multiple choice examination in middle school mathematics designed to promote the development and enhancement of problem solving skills.
The examination provides an opportunity to apply the concepts taught at the junior high level to problems which not only range from easy to difficult but also cover a wide range of applications.
Many problems are designed to challenge students and to offer problem solving experiences beyond those provided in most junior high school mathematics classes.
Calculators are not allowed starting in 2008. High scoring students are invited to participate in the AMC 10.
A special purpose of the AMC 8 is to demonstrate the broad range of topics available for the junior high school mathematics curriculum. This is done by competencies.
The AMC 8 has the potential to increase the perceptions of the importance of problem solving activities in the mathematics curriculum by stimulating these activities both preceding and following the examination —specifically by studying the solutions manual.
Additional purposes of the AMC 8 are to promote excitement, enthusiasm and positive attitudes towards mathematics and to stimulate interest in continuing the study of mathematics beyond the minimum required for high school graduation.
Developmentally, junior high school students are at a point where attitudes toward school and learning, and perceptions of themselves as learners of mathematics are solidified.
It is important that they be provided opportunities that foster the development of positive attitudes towards mathematics and positive perceptions of themselves as learners of mathematics. The AMC 8 provides one such opportunity.
We encourage all students in grades 6, 7 and 8 to participate in the AMC 8. All USA, USA embassy, Canadian and foreign school students in grade 8 or below are eligible to participate.
AMC 8 Intramural Awards
* A Certificate of Distinction is given to all students who receive a perfect score.
* An AMC 8 Winner Pin is given to the student(s) in each school with the highest score.
* The top three students for each school section will receive respectively a gold, silver, or bronze Certificate for Outstanding Achievement.
* An AMC 8 Honor Roll Certificate is given to all high scoring students.
* An AMC 8 Merit Certificate is given to high scoring students who are in 6th grade or below.
The members of the Committee on the American Mathematics Competitions (CAMC) are dedicated to the goal of strengthening the mathematical capabilities of our nation's youth.
The CAMC believes that one way to meet this goal is to identify, recognize and reward excellence in mathematics through a series of national contests called the American Mathematics Competitions.
The AMC include: the American Mathematics Contest 8 (AMC 8) (formerly the American Junior High School Mathematics Examination) for students in grades 8 and below, begun in 1985; the American Mathematics Contest 10 (AMC 10), for students in grades 10 and below, new in 2000; the American Mathematics Contest 12 (AMC 12) (formerly the American High School Mathematics Examination) for students in grades 12 and below, begun in 1950; the American Invitational Mathematics Examination (AIME), begun in 1983; and the USA Mathematical Olympiad (USAMO), begun in 1972.
On Thursday, May 11, 1950 the first Mathematical Contest, sponsored by the New York Metropolitan Section of the Mathematical Association of America (MAA) took place.
It was given in 238 schools to 6,000 students in the New York area only. Today the contest is taken in every state and around the world. It is translated into braille, French, Spanish and Chinese, and has evolved into a series of five contests.
1950-2009
The
American
Mathematics
Competitions
Help us celebrate 60 years of the
American Mathematics Competitions
by registering your school to participate in the 60th annual
American Mathematics Contest 12
and the 10th annual American Mathematics
Contest 10. The AMC 10 is
designed for 9th and 10th grade students, and the AMC 12 is designed for 11th and 12th grade students.
Participation & Eligibility
Both AMC 10 and AMC 12 are 25-question, 75-minute multiple-choice contests administered in your school by you or a designated teacher. The AMC 12 covers the high school mathematics curriculum, excluding calculus.
The AMC 10 covers subject matter normally associated with grades 9 and 10. To challenge students at all grade levels, and with varying mathematical skills, the problems range from fairly easy to extremely
difficult. Approximately 12 questions are common to both contests. Students may not use
calculators on the contests.
AMC 12 Eligibility – A student in a program leading to a high school diploma, and under 19.5 years of age on the day of the contest.
AMC 10 Eligibility – A student in a program leading to a high school diploma, under 17.5 years of age on the day of the contest, and not
enrolled in grades 11 or 12 or equivalent.
Home schools must indicate the site of the exam (not the student’s home) and the name of the proctor (not a parent) and attach this information to the registration form. Please call
the AMC office for details.
PURPOSE
The Mathematical Association of America wants to increase interest in mathematics and to develop problem solving through a friendly,
and fun, competition. We believe that one way to meet this goal is to identify, recognize, and reward excellence in mathematics through a series of national contests.
