The Math League.

A contest series for grades 1 to 12, founded in 1977 and now entered by more than a million students a year. It is deliberately less austere than an olympiad: the problems are lively and drawn from ordinary situations, and because everything is in English, reading the question is part of the test.

At a glance

What the series is, and how it runs.

The Math League was founded by two American mathematics educators, Steven R. Conrad and Daniel Flegler, and first held in 1977. Their stated aim was to make students enjoy mathematics and use it on real problems rather than fear it.

By year group

Four different papers across twelve years.

The youngest students sit a shorter paper of purely multiple-choice questions. From grade 3 upward the format is fixed at 75 minutes and mixes multiple choice with fill-in answers.

Note what happens to the question count: the older papers have fewer questions in the same time, which is the clearest indication that they expect more thinking per problem rather than more speed.

The three stages

How a student moves through the series.

Each stage is a genuinely different kind of assessment, which is unusual - most series simply make the next paper harder.

First stage, December

A timed paper sat on one Saturday, on paper or online. The questions are deliberately flexible and close to everyday situations, meant to leave students understanding and enjoying mathematics rather than intimidated by it.

Second stage, January to February

Open book, and taken over weeks rather than hours: candidates download the questions after registering and upload answers before the deadline. Open to grades 3 to 9 who earned a certificate in the first stage.

Summer finals, United States

Held with Princeton, Columbia and Williams College, and set jointly with them. Students compete alongside entrants from the US and Canada and attend teaching from faculty at those institutions.

The second stage

An open-book round that works like research.

This is the most distinctive thing the series does, and it is worth understanding before entering: the second stage is not a harder version of the first.

Grades 3 to 6: think, do not rush

The questions differ in form from a conventional competition paper and are not especially hard. What they require is careful, sustained thought - the organisers make the point that genuinely important ideas are usually simple and close to ordinary life.

Grades 7 to 9: read, then solve

Candidates first read a mathematical topic written in English - number theory, for instance - and then answer a set of questions on it, rising in difficulty. The reading is the point; the questions test whether it was understood.

Research is allowed, including online

Students may look material up, including on the internet, and may ask experts. Very few contests permit this, and it changes what is being measured from recall to the ability to find and use unfamiliar mathematics.

But nobody may do it for you

The one hard rule is that no other person may do the work. The candidate has to complete the questions themselves and genuinely understand what they have done, which is what keeps an open-book round meaningful.

First-stage awards

Three certificates, and a place in the second stage.

The certificates are not cumulative - a student receives the highest one they qualify for. All three carry an invitation to the second stage.

The finals

Four rounds at the summer event.

The finals are split into elementary, middle and high-school groups, with the high-school group running at Stanford University and at Alphastar Academy in Silicon Valley.

Individual Round

Ten to fifteen questions worked one at a time, with seven to ten minutes allowed for each. Combined with the Speed Round, this decides the individual standing and the gold, silver and bronze medals.

Speed Round

Sixty fill-in questions in forty-five minutes - forty-five seconds a question. It is the opposite demand from the Individual Round, and sitting both in one event is part of the design.

Team Round

Ten to fifteen questions worked by a team of five over one to two hours. This is where the collaborative half of the finals begins, and where dividing the paper well matters as much as solving it.

Relay Round

Five questions passed down a team, each member needing the previous answer before they can start. Updated answers can be passed forward more than once, and the fifth question is the hardest.

Preparation

How Hanlin prepares students for Math League.

Two things separate this series from a domestic competition: the English, and the fact that later stages reward reading rather than drilling.

Reading mathematics in English

The second stage asks grades 7 to 9 to read a mathematical topic in English and then work on it. Practice therefore includes reading unfamiliar mathematical prose in English, which is a skill separate from solving problems in it.

Problems from ordinary situations

Questions are framed around real settings rather than abstract statements. The trainable step is turning a described situation into a mathematical one quickly, and it is where younger candidates lose most of their marks.

Two opposite speeds

Forty-five seconds a question in the Speed Round and ten minutes in the Individual Round demand different habits. Students who reach the finals practise both, because doing one well does not prepare you for the other.

Choosing the level

Entering a year above is permitted and sometimes right for a strong student, but it changes the paper and the field. That decision is settled against a past paper rather than by ambition.

Hanlin has been entering students for Math League for years, and publishes what they got. The record is further down this page.

Programme formats

Five ways this is taught.

Group size is the whole difference between these. It decides how much of the tutor's attention a student gets and how far the course can bend to them, so it is worth choosing rather than accepting.

FormatGroup sizeWhat it suits
One-to-oneOne studentContent, pace and emphasis set by what this student actually needs rather than by a syllabus. The only format that can be rebuilt mid-course.
Small groupThree to eightOpens at three. Frequent discussion, and the tutor can slow down or move on according to what the group has absorbed. Most students chasing a higher award are taught in this one.
ClassEight to twelveTaught by the subject lead or a medal coach. Less back-and-forth, so it suits a student who will say when something is unclear.
Large classTen to twentyFor students in the middle of the placement range, and a way to try a competition before committing. Students often move to a small group or to one-to-one afterwards.
Past-paper classNo capPast papers worked through in sequence in the weeks before the sitting. Free to students already enrolled.

Course length for Math League is set after a placement paper. The gap between where a student is and what the paper asks for is what the course has to close, and that gap is not the same for two students in the same year group.

How it runs

Six steps, four people on your side.

The same process for every student, so that nothing depends on one tutor remembering to do it.

Step 1

Pre-course assessment

A placement paper before anything is booked, so the course tier is chosen on evidence rather than on a year group.

Step 2

Tutor matching

A subject tutor is matched to the result, and their full background is provided before you agree to it.

Step 3

Plan and group

A study group opens with four people on one student: the tutor, a planner, a supervisor and an academic manager.

Step 4

Scheduled teaching

The teaching office sets the timetable around the competition date and school term, and teaching begins.

Step 5

After-class reports

What was covered, and how the student handled it, reported after every lesson.

Step 6

Homework follow-up

The teaching assistant and the form teacher both check that homework is done, which is where most preparation quietly fails.

FAQ

Math League, briefly answered.

What students and families ask before entering.

Who can enter Math League?

Students in grades 1 to 12. A student may register for a year group above their own - a grade 5 student can sit the grade 6 paper - but the level determines both the questions and the field they are ranked against.

What is the first-stage paper like?

Grades 1 and 2 sit 45 multiple-choice questions in 45 minutes. Grades 3 to 7 sit 35 questions in 75 minutes, and grades 8 to 12 sit 30 questions in the same time, both mixing multiple choice with fill-in answers.

Can the first stage be taken online?

Yes. It can be sat on paper or online through the official Math League site. Online candidates need a laptop or tablet with a camera to answer on and a smartphone with a camera for invigilation; video is recorded throughout and messaging apps are not allowed.

Who qualifies for the second stage?

Students in grades 3 to 9 who earned an Honor Roll of Distinction, Honor Roll or Certificate of Achievement in the first stage - that is, anyone finishing in the top half of the field.

Is the second stage really open book?

Yes. Candidates download the questions and upload answers before a deadline weeks later, and may research the material including online and ask experts. The one prohibition is having someone else do the work.

What are the first-stage awards?

Honor Roll of Distinction for the top 8%, Honor Roll for the top 25% and Certificate of Achievement for the top 50%. They are not cumulative - a student receives the highest one they qualify for - and all three lead to the second stage.

What happens at the summer finals?

They run in the United States with Princeton, Columbia and Williams College, in four rounds: Individual, Speed, Team and Relay. Individual and Speed decide the individual medals; the team rounds decide the team standing and the Math League Cup.

Is the result useful for applications?

It is accepted as supporting evidence in applications to North American secondary schools and universities. Because the whole series runs in English, it also demonstrates working in the language rather than only mathematical ability.

Math League enquiries

The interesting round is the one nobody prepares for.

Most families plan for the December paper and are surprised by the open-book second stage, which rewards reading rather than drilling. Tell us the student’s year group and an advisor will map both stages against the season.
