Prime Factor Math Circle


Welcome to Prime Factor Math Circle (Seattle, Eastside).

Prime Factor Math Circle is an extracurricular math program for elementary and middle-school students. In our classes, students develop creative thinking and problem-solving skills, as well as learn the principles of logic and math reasoning. Our curriculum includes interesting and educational math topics that generally lie beyond school curriculum.

Prime Factor Math Circle students meet weekly in a small-class setting. A circle session consists of an hour and a half of interactive teaching, mathematical discussion and problem-solving. The problems and discussion topics are selected to stimulate students' creative abilities and to develop their problem exploration skills and mathematical reasoning. Some of the class time (especially in circles with younger students) is devoted to mathematical contests and tournaments.

2014-2015 Prime Factor Math Circles and Programming Classes

Junior Circle 1 (grades 3-4):

In this circle, we spend a lot of time working on challenging problems, mastering useful problem solving techniques, and learning math concepts and ideas through theoretical discussions and hands-on experience.

Junior Circle 2 (grades 4-5):

in this class, we use the same principals and approaches as in Junior 1 circle. We explore a wide variety of new and exciting math topics, while building up on the ideas and knowledge that comes from Junior 1 class. We emphasize topics that encourage mathematical inquiry and develop logical and problem-solving abilities.

Junior Circle 3 (grades 5-6):

This circle is devoted to more advanced math concepts and more challenging problems than Circle 2. It is about both hands-on problem solving and building a solid foundation for our middle school program. While working on a variety of math enrichment topics and problem solving techniques, the students will be exposed to all elements of mathematical inquiry: creative exploration, rigorous proof, and clear explanation.

Math Circle First Year (grades 6-7):

For students who want to know more about the world of extracurricular mathematics. Potential students should be ready to explore, learn, and work on challenging problems. This class is open to Junior Circle graduates and to new students.

Math Circle Second Year (grades 6-8):

For students of grades 6-8 who are familiar with the First Year topics or are ready to put in extra work of catching up with our First Year program.

Math Circle Third Year (grades 7-9):

For students of grades 7-9 who are familiar with the Second Year topics.

Math Circle Fourth Year / AMC 10 prep (grades 8-10):

The curriculum of this circle includes two components. The first one is the “extracurricular math” component - proofs and math reasoning. The second one is AMC 10 preparation - learning advanced school math.
(AMC is the most prominent US middle and high school math competition. AMC competitions reward deeper understanding and proficiency in advanced school math – algebra, geometry, and other topics.)
