# Contests

First of all, the LHS Math Club runs its own competition twice a year. The**Lexington Mathematics Tournament**is the annual competition for middle school students hosted by the LHS Math Team. Throughout the year we accept original problem submissions and also seek volunteers to help organize different parts of the competition.

The LHS Math Club also participates in over thirty math competitions every year. An overview of some will be below.

### Local Competitions

The

**Massachusetts Math League**is a local competition held on Thursdays after school at various high schools in the area, once a month October through March. 10 regulars and 10 alternates are invited to participate every meet, and meets are extremely exciting. The meet hosted in Lexington, usually in January, is typically open to all math team members.

As a result of our strong finishing scores each year in the MML, we have for the last few decades been invited to the

**MAML State Meet**, held in early April, and the

**NEAML New England Meet**, held at the end of April or the beginning of May. Eight team members are invited to participate for each competition.

The Lexington High School math team has won all NEAML New England Meets in the past five years.

The

**Massachusetts Math Olympiad**is a competition open to all math team members. The first round is a multiple choice exam taken during school in October, and high scorers are invited to the second round, a proof contest taken at the beginning of March.

### National Competitions

The

**American Mathematics Competitions**are a set of national competitions sponsored by the Mathematical Association of America. The first competitions in the series are the AMC 10, open to all students in 10th grade or below, and the AMC 12, open to all students, which happen in February. There are two separate testing dates - one can only take one test per testing date, but students in 10th grade or below make opt to take the AMC 10 on one date and the AMC 12 on the other. High scorers are invited to participate in the American Invitational Mathematics Examination (AIME) in March, and high scorers on the AIME are invited to the USA Mathematical Olympiad and USA Junior Mathematical Olympiad in April. Those top students from those olympiads are invited to the Math Olympiad Summer Program, a summer camp that trains the students and determines who gets to attend the International Math Olympiad. Also see the AMC page.

The

**US Math Competition Association Championship**is a team competition that teams qualify for by excelling on college competitions (PUMaC, CMIMC, MMATHS, and a few others not listed below). We usually are able to send 1-2 teams to attend the championships.

In the 2019-2020 school year, the US Math Competition Association also had an asynchronous competition which we had three teams compete in. This competition’s purpose was to offer more opportunities for teams to qualify for the US Math Competition Association Championship, in which

**our team eventually won the Challenger division that year**. Due to competitions being online in the 2020-2021 school year, this asynchronous “Online Qualifier” did not occur in that school year.

In the 2021-2022 school year, this competition is not running due to COVID-19’s logistical challenges.

### College Competitions

The

**Harvard-MIT Mathematics Tournament**is an international math competition organized by undergraduates from Harvard and MIT, held at one of the two campuses each year in February. 24 students, in teams of 8, are invited to participate. The

**Harvard-MIT November Tournament**is a similar competition geared toward local schools and less-experienced problem solvers, held in November. All math team members are invited to participate, but must try out to be placed on a team of 4 to 6 students. Lexington High School has had the

**highest placing tean**of any fully (non-magnet) public school in the United States for the past three years at HMMT February contests.

The

**Princeton University Mathematics Competition**is an international math competition organized by Princeton undergraduates (similar to HMMT). All math team members are invited to try out. We send one or two teams of 8 students every year. As it is rather far, participants may have to pay a fee for transport/hotel/etc. Last school year, our A team placed tenth place in the A division, making us the highest placing team of any fully (non-magnet) public school in the United States for PUMaC 2021*.

The

**Carnegie Mellon Informatics and Mathematics Competition**is an international math competition organized by undergraduates from Carnegie Mellon University. We usually send 3 teams of 6 students every year. Participants also have to pay a fee for transport/hotel/etc. Last school year, our A team placed seventh place, again making us the highest placing team of any fully (non-magnet) public school in the United States for CMIMC 2022.

The

**American Regions Math League**is a national competition held at four college campuses around the country in June. Lexington High School is able to send a team of 15 students and some alternates, chosen by tryout, to compete at Pennsylvania State University.

As it is rather far, participants will have to pay a fee for transportation (which is typically a long bus ride), and live in the dorms at Pennsylvania State University. In 2022, Lexington High School's A team placed

**third**place onsite for Division A, making us the highest placing team of any school (both public and private) in the United States for ARML 2022.

The

**Math Majors of America Tournament for High Schools**is an international math competition organized by undergraduates from multiple universities, including Yale University. We usually send 2-3 teams of 6 students every year.

When competitions are virtual, the Lexington High School may attend additional competitions, including BMT (UC-Berkeley), DMM (Duke), SMT (Stanford), and HSMC (Georgia Tech).
