Math Circle at FAU

Spring 2025

Welcome to the home page of the Circle.

The main purpose of the circle is to have fun with mathematics while learning something in the process. We will be discussing and solving problems, having friendly competitions, playing mathematical games. Links to the material of previous sessions, as well as to other information will be provided below. While, as mentioned, the real purpose of this circle is to amplify the mathematical knowledge of students who like math, and do it in a fun way, we will also look at some AMC problems, and see how what was seen in the circle applies. We will be meeting on almost every other Saturday, beginning Saturday, January 11, 2025.

While the circle is originally thought of for middle school students, we will add a high school component if there is interest.

To keep this circle as useful as possible, it is important to have feedback from participants and parents and teachers of participants. Don't be shy, let us know what you think. What can we do to improve it? An occasional word of praise will keep us going strong, but constructive criticism can be more important.

It is important to emphasize what these circle meetings are NOT. They are not classes or lectures. Students are free to walk about and talk.

Beginning with this circle we will ask parents or guardians to register the students they plan to bring. Registration is free, but we want to have an idea of how many participants we will have. I should also mention that we will in general assume that students are coming to all sessions so that we can expand in session n what we started in session n-1. To get a real benefit from the circle, students should come regularly, not sporadically. Of course, all this is up to the students; they can come and leave whenever they please.

Source of the Problems: The majority of problems will come from very diverse sources, old AMC competitions, the Moscow Math Circle Problem book, historical sources (for example Fibonacci's Liber Abaci), etc. A few will be made up by us. Sources will not usually be credited but credits will be revealed upon request, if we know the source.

All meetings are from 2:30 to 4:00 p.m., on the Boca campus of FAU in PS 112.

 

We are asking parents or guardians to register their kids so that we have an idea of how many students we can expect. But we won't turn anybody away.
