Free AMC 8 learning, built around thinking
Don't memorize the trick. See why it works.
Mathinking teaches competition math the way a good tutor would: try something, notice the structure, make the reason visible, and then use the idea on a real problem.
How a Mathinking lesson works
The explanation comes after you have something to notice.
Instead of opening with a formula, lessons are built around the moment where the idea becomes useful—then they keep going until you can use it yourself.
- 01Try
Start with a problem before the idea is named.
- 02Notice
Use a visual, animation, or counterexample to expose the structure.
- 03Name
Only then compress the pattern into a reusable mathematical idea.
- 04Transfer
Recognize the same idea in a new setting, often inside an AMC problem.
- 05Practice
Use the idea independently until it starts to stick.

All 50 lessons are on Learn. You can follow the curriculum or jump directly to the idea you need.
Fractions, rates, percent change, averages, graphs, and the number sense everything else leans on.
Variables, equations, systems, functions, lines, sequences, exponents, and roots.
Divisibility, primes, factors, remainders, cycles, digits, and bases.
Systematic counting, casework, combinations, paths, sets, and probability.
Angles, triangles, area, similarity, circles, transformations, solids, and nets.
Work backwards, eliminate possibilities, track invariants, and force guaranteed outcomes.
Not sure where to start?
Start from the problem you're actually having.
What's new
Mathinking is no longer just a problem browser.
50 guided lessons. Foundations through problem-solving strategy are available from Learn.
Practice has its own home. Filter the AMC bank by skill and difficulty without mixing it into the lesson catalog.
Real problems stay connected. Lessons use AMC questions, written reasoning, and animated explanations when they genuinely help teach the idea.
