Your team captain drops a link in the group chat: registration for the MathWorks Math Modeling Challenge is open, and it costs nothing to enter. You have sat the AMC. Maybe the AIME too.
This one has no 25 questions, no bubble sheet, and no blank worth partial credit. Over a 14-hour window, your team picks from a Friday-to-Monday weekend; three to five of you build a model for a real-world problem and turn in a paper instead of an answer sheet. Here is what M3 asks for, who can enter, what it pays, and whether Gonit is worth using to get ready.
Key Takeaways
- Teams of 3 to 5 students, plus one coach, get one continuous 14-hour block chosen from a Friday-to-Monday weekend to solve one open-ended, real-world modeling problem and submit it as a written paper.
- Only US juniors and seniors, plus a short list of defined equivalents, can enter. Entry is free, and SIAM and MathWorks put $100,000 into scholarships across the winning tiers each cycle.
- Gonit trains multiple-choice speed for grades 1 through 10. M3 grades a written paper from juniors and seniors. Those two things do not overlap yet.
What Is the MathWorks Math Modeling Challenge?
SIAM, the Society for Industrial and Applied Mathematics, has run M3 every year since 2006, when Moody’s Foundation launched it as the Moody’s Mega Math Challenge. MathWorks became title sponsor in 2017. The format never changed: one real-world problem, one paper, no answer key.
Search up MathWorks Math Modeling Challenge and most of what comes back is an encyclopedia entry or a college-consulting page selling a prep package to a parent shopping for something that looks good on an application. Neither describes a team’s Friday night once the problem downloads.
Modeling is not the same skill as solving a problem someone already set up for you. Teams get an open scenario (past years have covered things like disaster logistics and resource distribution) and have to build their own approach: state assumptions, pick a method, run the numbers, and defend every choice in writing. A model gets judged on whether the assumptions hold up and the reasoning is sound, not on whether one number matches a key.
Who’s Actually Eligible
Grade, Age and Location Rules
M3 only opens to juniors and seniors. A freshman or sophomore, however strong, has to wait. The full list, per SIAM’s official rules: US high schools, including US territories and DoDEA schools; sixth-form students in England and Wales aged 16 to 19; and homeschool or cyber-school students aged 16 to 18 with a school affiliation. Nobody under 13 can compete, and a team can enter for at most two consecutive years.
Team Size and the Coach Requirement
Three to five students, one team, one paper. Every team needs a coach on record, usually a teacher or administrator, though a retired teacher or an outside math-club volunteer can fill the role too. The coach registers the team and handles logistics beforehand. Once the problem downloads and the 14-hour clock starts, the coach cannot help. The paper has to be the team’s own work, cited sources included.
What Challenge Weekend Actually Involves
Challenge weekend runs Friday through Monday, and every team picks its own continuous 14-hour window somewhere inside it. No fixed start time, no proctor in the room. Once a team downloads the problem, the clock starts and cannot be paused.
The MathWorks Math Modeling Challenge gives teams one real-world problem and 14 continuous hours to build a mathematical model, write up the reasoning, and submit a paper. There is no number to circle. Judges score the assumptions, the method, and how clearly the team explains both.
Inside that window, teams can use computers, spreadsheets, coding tools, textbooks and the open internet, and they are expected to. What is off-limits is outside help: no calling a parent, no emailing a teacher who is not the coach, no crowdsourcing an answer online. Every source used has to be cited in the paper, same as a real research report.
How M3 Is Different From Everything Else in This Track
Every other competition in this cluster gives you a number to check. AMC and AIME are timed and multiple-choice or short-answer. ARML, HMMT and PUMaC add team and proof rounds, but a proof still ends in a fixed statement that is either right or wrong. M3 ends in a paper a judge scores on argument quality, with no rubric shortcut to memorize in advance.
That changes what prep means. AMC or AIME prep means drilling problem types until pacing gets automatic. M3 prep means writing more, not solving more: taking a real dataset, building a rough model, and rewriting the explanation until a stranger could follow it without you in the room. Teams that treat M3 like one more timed test tend to run out of the 14 hours with a half-finished paper and strong math nobody else can follow.
Is Gonit a Fit for M3 Prep?
Gonit’s own numbers make this section short. The question bank covers grades 1 through 10, with grades 11 and 12 still in progress. M3 is open only to juniors and seniors, which puts the entire eligible population for this competition outside where Gonit is fully built out right now. ARML, HMMT, PUMaC and the Stanford Math Tournament all draw from grades 9 through 12, so most of their field is already covered here. M3 does not have that overlap.
The format gap is separate and just as real. Gonit’s practice style is multiple-choice and short-answer questions, with a hint before an attempt and a full explanation after a wrong one. That trains speed and accuracy on problems with a single correct number. M3 grades a 14-hour written paper with no correct number in it.
A student who drills Gonit daily will walk into Challenge weekend with sharper number sense and faster mental math, which is not nothing on a modeling problem full of arithmetic. It will not teach them how to state an assumption, structure a model, or write a page a judge wants to keep reading. Put plainly: this is the one piece in this track where Gonit helps around the edges and does not train the event itself.
None of that means skip Gonit. It means use it for what it does well: build the arithmetic fluency and topic range M3’s data problems will lean on, then find modeling and writing practice somewhere that grades a paragraph instead of a bubble.
What Winners Get
SIAM and MathWorks put $100,000 into scholarships each M3 cycle, and the program has paid out more than $2 million since 2006.
| Tier | Prize |
|---|---|
| Champion team | $20,000 |
| Runner-Up | $15,000 |
| Third Place | $10,000 |
| 3 Finalist teams | $5,000 each |
| 6 Semifinalist teams | $1,500 each |
| 19 Honorable Mention teams | $1,000 each |
Finalists also get a paid trip to the live judging event in New York City each spring, and none of it depends on doing well in any other competition first.
How to Start Preparing (If a Team Wants to Try)
There is no past-paper archive to drill the way you would AMC past papers, and reproducing one of SIAM’s released problems or a team’s winning paper here would not be fair use anyway.
What is available: SIAM’s own site archives past problem statements and winning papers by year, and reading two or three (not to copy the math, but to see how a strong team structures an argument) is one of the more useful hours a team can spend before Challenge weekend.
Beyond that, build the habit on your own material. Take a real, messy dataset (school attendance, a local transit schedule, weather data for your area) and try to model something about it in under two hours: state an assumption, build a rough formula, write two paragraphs defending it. Do that three or four times before Challenge weekend and the clock stops being the scary part.
Our AIME problems guide is a good place to keep sharpening the number sense that still matters here, and a student with M3 on the radar is often eyeing how to qualify for the IMO in the USA a track or two down the line.
M3 will not fit neatly next to a pacing chart or a cutoff score, and that is the point of trying it once. Build the arithmetic here, build the argument there, and let the paper speak for the team.
FAQ
What is the MathWorks Math Modeling Challenge?
The MathWorks Math Modeling Challenge (M3) is a free contest from SIAM and MathWorks for teams of three to five US juniors and seniors. Over one 14-hour window, a team builds and writes up an original mathematical model for a real-world problem, with no fixed correct answer.
Who is eligible for the M3 Challenge?
US high school juniors and seniors (including territories and DoDEA schools), sixth-form students aged 16 to 19 in England and Wales, and some homeschool students aged 16 to 18 with a school affiliation. No one under 13 can compete, and a team can enter for at most two consecutive years.
Is the M3 Challenge free to enter?
Yes. There is no entry fee. SIAM and MathWorks fund the competition and put $100,000 into scholarships each cycle, from the Champion team’s $20,000 down through the Semifinalist and Honorable Mention tiers.
How is M3 different from AMC or HMMT?
AMC, AIME and HMMT are timed tests or proof rounds with a fixed correct answer. M3 gives a team 14 hours to build an open-ended model and submit a written paper, graded on reasoning and assumptions rather than a matching number.
