Prime Factor Math Circle is an extracurricular math
program for elementary and middle-school students. In our circle, 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 often lie beyond the school
program.

Prime Factor Math Circle students meet weekly in a
small-class setting. The circle sessions consist of an hour and
a half of interactive teaching, mathematical discussion and problem-solving. The problems and
discussion topics are selected to stimulate the 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 competitions.

### 2013-2014 Prime Factor Math Circles

In the 2013–2014 school year, Prime Factor Math Circle will operate
circles of seven different levels:

#### Elementary School Circle 1 (grades 3-4):

In this circle, we will spend a lot of time working on problems
and getting to know math concepts and ideas through hands-on
experience.

#### Elementary School Circle 2 (grades 4-5):

For students
who like to ask questions and search for answers. Math is used
as a tool for developing logical and
problem-solving abilities.

#### Elementary School Circle 3 (grade 5):

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 Elementary School 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 (grades 8-10):

This circle is for students to are familiar with the Third Year topics.
