What does Prep cover for Math Olympiads (MOEMS)?

Math Olympiads (MOEMS). Each Level has its own chapter map, practice rounds, sealed practice exams with every answer and worked solution at the end, and a published gate to the next Level.

When is the next Math Olympiads (MOEMS) date?

Nov 9, 2026 – Mar 29, 2027 · MOEMS Contest 1 · Nov 9–30, 2026 (5 contests, Nov–Mar). Always check the organizer's site before registering.

What Math Olympiads (MOEMS) covers

MOEMS rewards resourceful thinking over memorized formulas. This map organizes the problem set into five domains — arithmetic and number, fractions and algebra, word problems and logic, counting and patterns, and geometry — each laddering from a single technique toward the full domain.

Unit questions open after sign-in with a Series pass. Each child's first round is free, with its summary.

Arithmetic & Number Foundations
Fast, clever computation and the divisibility structure of the whole numbers.
3 units
- Clever Computation & Mental Math — Regrouping sums, smart multiplication, squares, and powers to compute without a calculator.
- Number Sense: Factors & Multiples — Factors, common factors, multiples, divisors, and the digits that build a number.
- Primes, Remainders & Divisibility — Primes and prime factors, GCF and LCM, remainders, digit sums, and cyclic units digits.
Fractions, Ratios & Algebra
Proportional reasoning and the first steps toward solving with unknowns.
2 units
- Fractions, Ratios & Percents — Comparing and combining parts of a whole through fractions, ratios, and percents.
- Algebra & Equations — Setting up and solving equations, including linear relationships, for an unknown.
Word Problems & Logic

A sample question from Math Olympiads (MOEMS)

A pipe fills a tank in 12 minutes. What fraction of the tank does it fill in one minute?

Answer: $\dfrac{1}{12}$

Worked solution

In 12 minutes it fills 1 whole tank.
In 1 minute it fills 1/12 of the tank.

Read-only. Every other question opens after sign-in; each child's first round is free.
