Interesting topics and intriguing problems will be explored in a friendly setting, providing ample challenges for high school students of varying levels. The topics include number theory, algebra, geometry, combinatorics, and more. The courses also address subtle mathematical ideas, including the nature and construction of proofs. Problem posing and problem solving are emphasized throughout.

In the descriptions of our circles given below, we mention the age and grade level of the student, but this is less important than mathematical preparation: there are high school juniors and sometimes seniors in our Math Circle A, enjoying mathematics right alongside freshmen and sophomores, as well as younger students who are ready for the challenges of our Math Circles B and C. If in doubt, please ask, and we'll be happy to offer guidance on choosing the right level class.

Where: | NYU Courant Institute, 251 Mercer St (map). Room 202. |

Instructor:
| Larry Zimmerman. |

In response to students’ requests, NYMC offers a four-part AMC course this fall; three sessions in December, and a follow-up session before the AMC is administered in February. Priority will be given to high school students whose schools do not offer the AMC contest. (NYMC will help participants find a place to take the AMC.)

While NYMC does not focus on competitions, some competitions are a source of beautiful, intriguing problems, and provide exposure to a variety of interesting mathematics. The American Mathematics Contest (AMC) is such a contest. What started as a local competition sponsored by the Mathematical Association of America (MAA) in 1950 has become the premier mathematics competition of America--reaching up to 400,000 students today. It is a 25 question, 75 minute multiple choice competition that covers a broad spectrum of high school topics.

A selection of problems from AMC 10 and AMC 12 will motivate the study of deeper mathematical topics and introduce interested students to this competition’s hidden mathematical gems. Check these links for some past AMC problems.

Please read the information pages at AMC 10 and AMC 12 to learn about the contests before applying for this course.
