Euler AMC and Galois MATHCOUNTS

The Colorado Math Circle will be offering weekly afterschool problem-solving sessions on Zoom every Thursday, 4:15-5:30 pm. These sessions are for advanced middle and high school students who wish to improve their mathematical problem-solving skills.

We expect to have three groups:

  • Euler AMC Advanced: focusing on AMC 12, AIME, and ARML level problems
  • Euler AMC: focusing on AMC 10 level problems
  • Galois MathCounts: focusing on state level MathCounts problems

FAQ

What are Colorado Math Circle meetings like?
They vary. Often a speaker will give a math talk on a specific topic. Past Euler Group topics have included generating functions, cyclotomic polynomials, dynamical systems, synchronization, graph theory, computability theory, knot theory, and olympiad inequalities. Past Galois Group topics have included parity, golden ratio, Pascal's triangle, Catalan numbers, recursion, and knot theory.

At most meetings we have time for group problem solving. The problems may require a numerical answer or may require a proof. (The word "proof" sounds intimidating but it just means you need to show that something is true.)

During problem solving sessions, students are free to collaborate with other students. We encourage students to present solutions at the board. This is an excellent way to practice explaining mathematics to others.
