Please read these instructions carefully and be sure to complete all the steps involved. It is the advisor's responsibility to make sure that teams follow all steps required for participation in IM2C.

Note that IM2C is in the USA Eastern time zone: all times given in these instructions are in terms of Eastern Standard Time (EDT) except where local time is noted.

Your Team(s) Online:

Each team will be assigned a control number.

Be sure to use a valid current email address so that we can use it to contact you at any point before, during, or after the contest, if necessary.

Preparing a Team

  1. Go to the IM2C web site and review the rules, guidelines and problems to prepare your students.
  2. Ensure that students have access to computers that enable them to word process, use a spreadsheet, and dynamically model both graphs and geometric relationships. In addition, students should have access to graphing calculators.
  3. It is both legitimate and desirable to coach or otherwise prepare your team(s). Visit the IM2C web site at and click on Sample Problems to prepare your students.
  4. All parents of students participating in the contest must sign a Parental/Guardian Authorization Form making their child's work available (with confidentiality assurance) for use in example and training materials for IM2C professional development activities. Additionally, should their team be designated as an Outstanding winner, the student's Solution Paper (or solution abstract) will be published. THIS AUTHORIZATION FORM MUST BE DOWNLOADED FROM THE INTERNET AND SENT HOME WITH EACH STUDENT BEFORE THE CONTEST PERIOD. SIGNED AUTHORIZATION FORMS FOR EACH STUDENT MUST BE INCLUDED WITH SOLUTION PAPERS FOR CONSIDERATION BY THE JUDGES.

Preparing a Solution Paper

  1. The contest problem will become available at 3:01 pm EST on Monday, March 8, 2021 for country/region representative/organizer to acquire. When teams are ready to compete the team advisor must login to their country/regional website to view the problem, or acquire the problem from their country/region representative/organizer. Once you view the problem we recommend that you print out a copy for your students at the beginning of your contest period.
  2. Teams may use any inanimate source of data, materials, computers, software, references, websites, books, etc. Be sure to credit all sources used.
  3. Teams may not use any person (other than team members) to discuss or obtain ideas for solving their problem nor may they seek help in obtaining an answer from the teams' advisor or anyone else. Any team that discusses the problem with anyone in a position to supply them with information reflecting experience or professional expertise will be disqualified. The relevant issue is one of intent: each team of students is expected to develop all of its substantive analysis without the help of others.
  4. Partial solutions are acceptable. There is no passing or failing cutoff score, nor will numerical scores be assigned. The IM2C judges are primarily interested in a teams' approach and methods.
  5. Papers must be typed and in English with a readable font of at least 12 point type. NOTE: Papers may be submitted to the local representative in their native language but must be translated into English prior to the contest deadline. The local representative must certify that any translation is of the actual paper submitted, i.,e. no changes have been made during the time it takes to translate the paper. The translation must be a word for word translation and no improvements may be made. If your country chooses to allow teams to submit papers in their native language you must incorporate translation time into your contest window as the final English solutions must still be received by the contest deadline 3:00 p.m. EDT on Friday, May 21, 2021.
  6. Your submission should consist of a 1 page Summary Sheet and your solution cannot exceed 20 pages for a maximum of 21 pages. (The appendices and references should appear at the end of the paper and do not count toward the 20 page limit.)
  7. The solution must consist entirely of written text and possibly figures, charts, or other written material only. No non paper support such as computer disks will be accepted.
  8. Each page of the solution must contain the team control number and the page number at the top of the page; we suggest using a page header on each page for example: Team # 2021000 page 6 of 13.
  9. The names of the students, advisor, or institution must not appear on any page of the solution. The solution must not contain any identifying information other than the team Control Number.
  10. Any preparation rule not followed is grounds for disqualification.
  11. Teams should keep in mind the following guidelines while preparing their solution papers:

Preparing and Submitting a Solution Paper

  1. The Summary Sheet
    Type a summary of the teams solution this should be the first page of your solution.
    The summary is a very important part of your IM2C paper. The judges place considerable weight on the summary, and winning papers are sometimes distinguished from other papers based on the quality of the summary. To write a good summary, imagine that a reader may choose whether to read the body of the paper based on your summary. Thus, a summary should clearly describe your approach to the problem and, most prominently, what your most important conclusions were. The summary should inspire a reader to learn the details of your work. Your concise presentation of the summary should inspire a reader to learn the details of your work. Summaries that are mere restatements of the contest problem, or are a cut-and-paste boilerplate from the Introduction are generally considered to be weak.
  2. Teams must end all work on the Solution Paper at the end of the team's consecutive 5 day period, or by 3:00 p.m. EDT on Friday, May 21, 2021.
  3. Send an electronic copy of the Solution Paper by email:
