What is TJIMO?

The Thomas Jefferson Intermediate Math Open (TJIMO) is a contest that the Thomas Jefferson Varsity Math Team holds for middle schools in the Washington, DC area. Students learn a variety of problem-solving strategies from experienced VMT student coaches and apply these strategies in a mathematics competition.


Sponsors allow us to provide the best experience possible for TJIMO participants by helping us host a competition full of learning, collaboration, fulfillment, and fun. Our full list of sponsors can be found on the sponsors page.

How Does the Contest Work?

TJIMO consists of four rounds of tests that challenge students' mathematical problem solving skills. A large block of the event is dedicated to coaching, in which students are assigned to small groups and learn strategies from VMT student coaches. See below for more details on each round.

  • Individual Round: The individual round is a one hour 30 problem round modeled after MATHCOUNTS' sprint round. Top scorers in the individual round will recieve awards at the end of the event. Scores from this round is also used to create balanced teams for the later rounds.
  • Coaching: After the individual round, students will be assigned to small groups and be coached by VMT members. They will be able to go over problems from the individual round and learn new strategies that will help in the team rounds later.
  • Team and Power Rounds: The team and power rounds consists of harder problems in different formats based on those seen in college math competitions. Students will be given sample rounds during coaching to familarize themselves with the format and learn how to write formal proofs.
  • Guts Round: The guts round is a special team round in which students are given several consecutive sets of problems and try to solve them as fast as possible.
  • Orienteering Round: The orienteering round involves solving problems in different locations around the building. Students work together to finish all the problems.


Q: Who can participate?
A: Middle schoolers from grades 6-8 that are currently taking Geometry or a lower level math class in school. We only allow 6th graders in elementary school to attend if this is their last year of eligibility (i.e., they are currently enrolled in Algebra I and plan on taking Geometry over the summer or are currently enrolled in Geometry). Elementary schoolers must also have a parent or teacher present at the competition for the entire duration.

Q: Who can register?
A: ONE math teacher or math team coordinator from each school can register students from their school to participate in TJIMO.

Q: How many students can attend from a school?
A: Up to 7.

Q: Can I register as an individual or homeschool student or with an organization outside of my school?
A: If you are homeschooled, you may register individually and indicate that you are homeschooled on the form. If you attend a public or private school, we ask that you ask your school’s math teacher/math team coordinator to register for you. We do not allow non-school organizations to participate. Please email us at if you have any questions.

Q: What is the role of the teacher/coordinator?
A: The role of the teacher/coordinator is simply being the link between us, the organizers, and the students - an essential role at TJIMO. In other words, they will be responsible for making sure the students are at the right place at the right time and relaying information to students.

Q: Will students from the same school compete as a team?
A: No, students will be assigned to teams balanced by math level during the individual round.

Q: What will students need for the competition?
A: Pencils, paper, a calculator, and a willingness to learn!
