About this free Competition Math course

Competition Math is a free training program for aspiring mathletes preparing for contests like the AMC 8, AMC 10, AIME, and MATHCOUNTS. It covers the advanced problem-solving techniques in number theory, algebra, geometry, and combinatorics that school math often skips, and builds the speed and creativity contest problems demand.

Each of the 15 weekly lessons mixes concept tutorials, contest-style practice problems, and competition strategies for recognizing patterns and avoiding common traps. The course was built by STEM for Others volunteers who have competed in these contests themselves, and it's designed to give you the skills and confidence to move up the ranks.

Who this course is for

The course is for students in grades 5 through 9 who enjoy math and want a challenge, whether they're preparing for a first contest or aiming to raise their AMC 8 score. You should be comfortable with pre-algebra. Strong younger students are welcome too.

Course outline

  • Week 1: What is competition math? An overview of the major contests, scoring, and problem-solving strategies.
  • Weeks 2-4: Algebra and number sense. Equations, fractions and ratios, and number sets and sequences.
  • Weeks 5-9: Geometry. Area and perimeter, types of triangles, triangle similarity, angles, and circles and quadrilaterals.
  • Weeks 10-12: Probability and counting. Probability, Venn and tree diagrams, and counting techniques and their applications.
  • Weeks 13-15: Number theory. Prime and composite numbers, GCD and LCM, and prime factorization techniques.

What you'll learn

  • Solve contest-style problems across algebra, geometry, counting, and number theory
  • Use counting principles, Venn diagrams, and tree diagrams to solve probability problems
  • Apply triangle similarity and angle relationships to geometry problems
  • Use prime factorization, GCD, and LCM to crack number theory problems
  • Manage time and choose strategies under contest conditions

How long it takes

Expect about 20 hours across 15 weeks, around 80 minutes per lesson. For the best results, add timed practice with past AMC 8 or MATHCOUNTS problems each week.
