COVID-19 Update

In response to the ongoing COVID-19 pandemic, LMT will take place online this spring. In lieu of the traditional multiple-round competition format, the 2021 LMT Fall will have two contest divisions, each consisting of a team round to be solved remotely over a longer span of time followed by a live guts round. For more information, see the Rules page.

Note: The competition format for the Online 2021 LMT Spring will be different than that of the Online 2020 LMT Spring, which consisted of a single team round.

General Information

The Lexington Mathematics Tournament (LMT) is a mathematics competition sponsored and run by the Lexington High School Math Club in Lexington, Massachusetts. The students at Lexington High School volunteer many hours to create an incredible experience for its participants.

LMT Fall is held every year in early December. The third annual LMT Fall was held online from Saturday, December 5th, to Saturday, December 12th.

LMT Spring is held every year in April or May. The twelfth annual LMT Spring will be held online from Friday, April 30th, to Sunday, May 9th.

Purpose

In high school, there are overwhelmingly many opportunities from all sorts of math leagues and contests and competitions, whereas there are far fewer in middle school (small regional leagues and MathCounts). We also realize that the transition from middle to high school math can be difficult. Inspired by other tournaments that provide challenging problems to high school students, it is our goal to offer middle school students an equally fun competition to help bridge the gap to high school mathematics and encourage them to continue their pursuit of mathematics in all of its forms.
