American Mathematics Competitions (zt)
The mission of the MAA's American Mathematics Competitions is to increase interest in mathematics and to develop problem solving through a fun competition. Teachers and schools benefit from the chance to challenge students with interesting mathematical questions that are aligned with curriculum standards at all levels of difficulty. In addition, students gain the opportunity to learn and achieve through competition with students in their school and around the world.
■The AMC 8 is a 25-question multiple-choice contest for middle-school students in grades 8 and below. The material covered is the middle school mathematics curriculum. Topics include probability, estimation, percentages, spatial visualization, everyday applications and reading and interpreting graphs. The AMC 8 is for students in the sixth through eighth grade, although accelerated fourth and fifth graders can also take part. The AMC 8 is 25 questions in length and is multiple choice with no penalty for guessing. The contest takes only 40 minutes. A student's score is the number of problems correctly answered. The AMC 8 is administered in schools in November.
■The AMC 12 covers high school mathematics, and is for students in high school who are under 19.5 years of age. The AMC 10 covers mathematics normally associated with grades 9 and 10 and is for students under 17.5 years of age who are not enrolled in grades 11, 12 or equivalent. Both contests are given in a convenient 75-minute interval, is 25 questions in length, with approximately 12 questions in common to both contests. The AMC 10 and AMC 12 are administered in schools in February.
■The American Invitational Mathematics Examination (AIME) is a 3-hour integer answer contest. Students will qualify for the AIME and can participate in the AIME only they score 120 or above on finish in the top 2.5% of the AMC 10, or if a student scores 100 or above or finishes in the top 5% of the AMC 12. The AIME is administered in schools in March.
■The USAMO is a six question, two day, 9 hour essay/proof examination. The Junior Mathematical Olympiad or USAJMO contest better meets the level of young students. The USAJMO new contest bridges the computational solution process of the AIME and the proof orientation of the USAMO. Both are administered the last week of April. All problems can be solved with pre-calculus methods. Approximately 270 of the top scoring AMC 12 participants (based on a weighted average) are invited to take the USAMO. Approximately 230 of the top scoring AMC 10 participants (based on a weighted average) are invited to take the USAJMO. U.S. citizens and students legally residing in the United States and Canada (with qualifying scores) are eligible to take the USAMO and USAJMO.
