Event Information

Event Contact

For questions about OIMT 2017 please contact one of the contest registration cooridnators


Registration is over. If you still need to register please email Katy or Raven.

By this point in time, students who qualifed at the regional contests should have recieived a formal invitation letter to the event.

How students are invited: 

Students are invited to OIMT based on their performance at the regional contests held at community colleges across the state. The top 12% in each category from each regional site will be invited (rounded up). An invitation will be sent to their high school once names are provided by the regional site contacts.

Students may also be invited due to exceptional scores on the AMC-10 and AMC-12 exams.  The qualifying AMC score for OIMT is 90 for both the AMC-10 and AMC-12 exams. If you have a qualifying AMC score please contact Katy or Raven.

Note about 7th and 8th grade students: We are NOT inviting 7th and 8th grade participants. The ONLY expection is if the student is taking a math class at a high school (this is different than taking a high school level class at a middle school). Please email with questions.

Parking/Campus Map:

Here is a map that shows where you can park for free.

Here is the OSU Campus map: The event will take place in various spaces in The Learning Innovation Center (LINC).

The agenda for May 13 will include one 60-90 minute written exam. Students will register in one of four levels: Geometry, Algebra II, Open I: Precalculus, or Open II: Calculus. This should match the level in which you competed at the regional contest. At any level you can expect some questions using mathematical concepts from across the various branches of mathematics.

Exams will be scored and the top ten students at each level will be recognized in the awards ceremony.

Students will also have the option to participate in a team problem solving event (see below).

Lunch will be included in the $30 registration fee.  Non-participants can purchase lunch for $10 and eat with the participants. 


Calculators will be allowed on all the exams and on the team event.  Use of laptops, other computers, cell phones, and other electronic communication devices will not be allowed in any of the events.    


Team Problem Solving Event General Description: 

All OIMT participants are expected to take the individual exam in the morning and have the option to participate in the team event in the late morning.  Awards will be given for both the individual and team events. 

For the team event, we will assign teams of four randomly created from the pool of students who respond by email below.  There will be two levels for the team event, level A: Precalculus/Calculus (Open I and II) and level B: Geometry/Algebra II.  Each level A team will have a mix of students from the Precalculus level and the Calculus level.  Each level B team will have a mix of students from Geometry and Algebra II.

Team Problem Guidelines and Judging Criteria:

The problem will be open ended.  That means there is no one “correct” solution.  While there may be many wrong ways to do it, there are also many “right” ways.  We expect a wide variety of different mathematical strategies to approach the problem.

  • Your team's poster should be a stand-alone presentation of your method(s) and solution(s).  You should present your work in an organized way so that the judges will be able to follow your solution process and understand your rationale for using particular mathematical techniques and processes.  
  • Judging:  Solutions will be judged based on three criteria:
  • The Math- The mathematics used should be appropriate to the problem and correct.  Creativity and sophistication of the mathematical tools used will also be a factor.
  • Communication- How well the mathematics is explained and supported is an important component of any solution.  The motivation and rationale for the use of a particular tool or for a particular “answer” should be clear.
  • Analysis of Solution- Once you have an answer (or answers) you need to explain the strengths AND limitations of that answer.  The judges will determine to what extent you have effectively understood the strengths and limitations of your approach.
