Which Math Competition Is Right for Your Child?

There are more math competitions for elementary students than most parents expect — half a dozen big ones — and from the outside they all sound vaguely similar. So you open six tabs, read six sets of rules, and close the laptop no closer to a decision than when you started.

This guide is the shortcut. Choosing the right math competition for your child comes down to three questions — who can sign up, what grade your child is in, and what your child is actually like — and once you answer those, the list narrows itself. If you want the full rundown of every contest first, our complete guide to math competitions for elementary students is the catalog. This post helps you pick one from it.

Start with the question that eliminates half the list

Before you compare problems, prices, or prestige, answer this one: who actually signs your child up? It splits every competition into two camps, and it decides your very first move.

• You sign up yourself. A handful of contests let you register your own child directly — you pay a per-student fee and they take the test, usually online or at a center, with no school involvement. Math Kangaroo is the best known, and MathCON and the RSM International Math Contest work the same way.
• The school signs up a team. MOEMS, Noetic, Continental Mathematics League (CML), and Math League all work this way. A teacher or parent volunteer registers a team and gives the test at the school. If your child’s school doesn’t already participate, you usually can’t enroll your child alone.

This is the fork that saves you the most time. There’s no point falling in love with MOEMS if your school doesn’t run it and you have no way to give it yourself. So before anything else, ask: do I want something I can start on my own this week, or am I willing to work through the school?

If the answer is “on my own,” you’re not limited to a single option. A few of the team contests also have built-in escape hatches for families:

• Math Kangaroo has a self-proctored virtual option — your child can take it from your kitchen table.
• Noetic offers an At-Home Edition where you act as the proctor, built for homeschoolers and families whose school doesn’t participate.
• CML explicitly allows a parent to proctor at home, with a homeschool rate of around $25 per child.

The two that lean hardest on a school are MOEMS (a teacher or parent signs up as the “PICO” and runs it for the class) and Math League (the official contest is bought and given by the school). Neither has a plug-and-play at-home edition, though a homeschool group can enroll its own MOEMS team. If a school team isn’t realistic for you, lean toward the individual options below.

Quick takeaway: Want to start this week without involving anyone? → Math Kangaroo, MathCON, or the RSM contest — plus Noetic’s At-Home Edition and CML’s homeschool option.

Three you can enter on your own, online

Because the “sign up yourself” group is the easiest place to start, here’s what those three actually look like:

• Math Kangaroo (grades 1–12). The classic individual entry point — a 75-minute, multiple-choice test held once a year in March, with no penalty for a wrong answer. It works at every elementary grade, not just the early ones, and you can choose an in-person center, a proctored online center, or a self-proctored virtual test at home. We have a full format guide plus free practice sets for grades 3–4 and grades 5–6.
• MathCON (grades 4–12). A parent can register a child as an individual participant for about $60. The first round is online — 32 multiple-choice questions in 50 minutes, taken during a winter window — and top scorers earn an invitation to an in-person national final each May.
• RSM International Math Contest (grades 1–8). Run by the RSM Foundation, this one is “open to all,” so your child doesn’t have to attend the Russian School of Mathematics to enter. It’s held each February — online for grades 3–8, and in person at RSM branches for the youngest students — with a small registration fee. Because it opens at grade 1, it’s a friendly option for younger kids.

Then match it to your child’s grade

Each competition has a youngest grade it accepts, and that floor knocks out more options than you’d expect. Here’s the earliest grade each one welcomes:

A few things worth pulling out of that table:

• If your child is in 1st grade, you still have two good options — Math Kangaroo and the RSM International Math Contest both open at grade 1. And Math Kangaroo keeps going all the way through 12th grade, so it’s never just a “little kids” contest.
• Grades 2 and 3 are where Noetic and CML shine. Both welcome the youngest competitors and lean encouraging, which matters enormously for a first experience.
• Grade 4 is when the field opens up. MOEMS Division E (grades 4–6), Math League, and MathCON all come online, so a 4th grader suddenly has the full menu.
• By 5th or 6th grade, a hungry kid can look ahead. AMC 8 is open to any student in grade 8 or below (and under 15.5 years old), and it even rewards starting young: its Achievement Roll recognizes students in 6th grade and below who score 15 or higher out of 25. A strong 5th or 6th grader can absolutely take it early.

Knowing a contest is open to your child’s grade is only the start. What actually suits them is the more useful question — and that comes down to personality.

Now the part that actually matters: what is your child like?

Two kids in the same grade can want completely different things from a competition. One lights up at a single fiendish puzzle; another loses heart if they can’t keep moving. Read the four sketches below and find the one that sounds most like your child.

The one who loves chewing on a single hard problem. Some kids will happily spend twenty minutes on one puzzle and feel cheated when it’s too easy. For them, look at MOEMS — each contest is just five problems in 30 minutes, and they’re deliberately “non-routine,” meaning your child can’t solve them by following a memorized procedure. CML is similar: roughly six word problems in 30 minutes, with answers written out. Both reward depth over speed, and both run as a season rather than a one-shot test, so the challenge keeps coming.

The one who likes momentum and lots of quicker problems. Other kids thrive on pace — they want to feel themselves making progress, question after question. Math Kangaroo (24 to 30 questions in 75 minutes), Noetic (20 problems in 45 minutes), MathCON (32 questions in 50 minutes), and Math League’s elementary contest (around 30 questions in about 30 minutes) are all built for that rhythm. A child who likes momentum will feel energized by these and frustrated by a five-problem olympiad.

The one who hates being wrong. If you have a perfectionist — the kind who freezes or melts down over a single mistake — pay attention to scoring. Math Kangaroo and AMC 8 don’t deduct anything for a wrong answer, so a guess never costs your child a thing. That sounds like a small technicality, but telling an anxious kid “you literally cannot lose points by trying” changes how they approach the hard questions at the end. Start them somewhere a wrong answer is free.

The one who wants to show their work, not bubble a letter. Plenty of kids find multiple choice unsatisfying — they’d rather lay out their reasoning. CML asks for written answers, and MOEMS rewards genuine problem-solving over pattern-matching. If your child takes pride in how they got there, those will feel more honest than the multiple-choice format of Math Kangaroo, MathCON, Math League, or AMC 8.

If more than one sketch fits your child, that’s fine — it just means you have more than one good option, and you can let the access and grade answers above break the tie.

Solo or team? Two different experiences

Underneath all of this is a quieter question about what kind of experience you want for your child: a personal challenge or a shared one.

A solo experience. Math Kangaroo, MathCON, and the RSM contest — and AMC 8 for older kids — put your child up against the problems on their own. You control the whole process, the goals are personal, and there’s no team to coordinate. This suits homeschoolers, kids who freeze up in group settings, and children who are motivated by beating their own last score.

A team experience. MOEMS, CML, Noetic, and Math League all wrap the test inside a season and a group. There are teammates, accumulating scores, and the low-key belonging of being on “the math team.” For a child who’s energized by being part of something — and for a school that wants a club to rally around — that social layer is the whole appeal.

One honest note so you’re not surprised: at the elementary level, even the “team” competitions are still solved individually. The team is really a scoring-and-belonging layer wrapped around what is still solo work — each child’s score simply feeds a combined team total. If you were picturing kids huddled over one problem together, these contests work differently: every child still tests alone.

Logistics and budget: the unglamorous tiebreaker

When two competitions feel equally good for your child, the practical details decide it.

Cost. The individual options run cheap to mid-priced per child: Math Kangaroo is roughly $18 if you register early and about $35 late, the RSM contest charges a small fee (recently around $15–25), CML’s homeschool rate is around $25 per child, and MathCON is about $60 for an individual entry. The team contests are priced per team — Noetic is $99 for a team of up to 30, MOEMS is about $175 for an early-bird team of up to 35, and Math League’s elementary contest is a flat school fee (around $45 for a set of 30 students). For the team options, the school or math club usually picks up the cost, not individual families.

Time commitment. Some of these are a single afternoon; others are a season. Math Kangaroo, Noetic, Math League, and MathCON’s first round are essentially one sitting. MOEMS spreads five contests across November through March, and CML runs a series of meets over the winter. If your family’s calendar is already full, a one-and-done test is a gentler commitment than a five-month season.

When each one lands in the year. If you like to plan ahead, here’s roughly when each falls:

• Math Kangaroo — the third Thursday in March (registration opens in mid-September).
• MathCON — an online first round across the winter (about January to March), then a national final in May.
• RSM International Math Contest — annually, each February.
• MOEMS — five contests, monthly from November through March.
• Noetic — twice a year, a fall round around November and a spring round around April.
• Math League (elementary) — spring.
• AMC 8 — a competition week in January.

Because several of these fall at different times of year, a keen child can comfortably do two or three across one school year without much overlap — Noetic in the fall, Math Kangaroo and the RSM contest in late winter, Math League in the spring.

If your school doesn’t run any of them, you still have a path: register for Math Kangaroo, MathCON, or the RSM contest yourself, use Noetic’s At-Home Edition or CML’s parent-proctor option, or bring a one-page summary to a teacher and ask them to start a team. None of it requires you to be a math person — mostly it takes one adult willing to print a test and start a timer. Our full competition guide walks through each of those options in more detail.

A 30-second decision tree

If you’d rather just be told where to start, follow this top to bottom and stop at the first line that fits:

1. Want to start now, completely on your own? → Math Kangaroo, MathCON (grade 4+), or the RSM contest.
2. Child in 1st grade? → Math Kangaroo or the RSM International Math Contest.
3. Grade 2 or 3, and you want gentle and encouraging? → Noetic (including the At-Home Edition) or CML.
4. Loves one hard problem, and the school will run it? → MOEMS (grades 4–6).
5. Homeschooling, no team, or you just want flexibility? → CML’s homeschool option, Math Kangaroo’s virtual test, or the RSM contest.
6. Advanced 5th or 6th grader who’s hungry for more? → add AMC 8 early.
7. School already runs one of these? → start there. At this age the path of least resistance is a genuine advantage — you’re just testing the waters.

Whichever you pick, here’s how to make the first one count

Which competition you choose matters far less than keeping the pressure low enough that your child wants to do another one. At this age, curiosity is the entire goal. Many of these tests don’t penalize wrong answers, most hand out participation recognition, and a 3rd grader doing Noetic for fun is already on the same road that leads to AMC 8 and beyond.

So pick one. Then keep prep small and steady: fifteen minutes a few times a week beats a frantic cram the night before. A standing, no-stakes habit is the easiest way in — our free Problem of the Week gives your child one interesting problem to chew on, and it costs nothing. If Math Kangaroo is your pick (it’s the most common first choice), our format guide shows exactly what the test looks like, and our free practice sets for grades 3–4 and grades 5–6 let your child try real problems with full solutions.

And for the day itself — the morning nerves, the waiting, the car ride home — our guide on what to expect at your child’s first math competition is the one to read the week before.
