Invitation Letter






Inspired by Tradition and History





As featured in mathematical history, emphasis on algorithm, computation and solving real world problem is the tradition of Chinese mathematics. Examples are demonstrated in The Nine Chapters on the Mathematical Art, or Jiuzhang Suanshu (composed from 10th – 2nd century BCE) which model and solve 246 real world problems covering widely agriculture, civil engineering, taxation and trade etc.

On the instrumental Colloquium of the International Commission on Mathematical Instruction (ICMI) in 1968, Hans Freudenthal made a strong plea to change mathematics education to include real world examples and modeling into mathematics education.  (Freudenthal, H. 1968, “Why to teach mathematics so as to be useful”, Educational Studies in Mathematics 1 (1) , 3-8. See also Gabriele Kaiser, 2014.)

Innovate for a Better Future



In the era of Big Data and Internet of Everything, through the combination of modeling and computation, mathematics has become essential tool and fundamental technology for the fourth industrial revolution and advancement of human civilization. Mathematical modeling has been an important part of STEM education in schools and universities. Modeling competencies are key aspects of the innovation competence and skills. For example, in the report by World Economic Forum, The Future of Jobs, the most important type of new and emerging jobs across practically all industries and geographies are data analysts which companies expect will help them make sense and derive insights from the torrent of data generated by technological disruptions.





IMMC 2016: Inclusive and Sharing Platform for All



International Mathematical Modeling Challenge (IMMC or styled as IM2C) is a team-based international contest in mathematical modeling for secondary schools. Teams from over 25 countries and areas will participate in the 2nd annual IMMC in 2016. Each participating country/area will select the best two teams through national or regional round of assessment to enter into international round of judgment by the International Expert Panel.


IMMC in Greater China will be the inclusive and sharing platform for all secondary schools at both local and international level by a student-centered approach. If your team is from the regions the Mainland, Taiwan, Hong Kong, and Macau, please register here. Your team’s solution paper will be read first by the Greater China Expert Panel.


IMMC is not a sport like tournament but educational teamwork. Working on an internationally-set mathematical modeling problem in IMMC 2016, you will bring into full play your potential in problem solving, innovation and teamwork through your solution paper. Also, you will have chance to win awards recognized as Greater China Outstanding, Meritorious, Honorable Mention, and Successful Participation. Teams who are selected into the final round of Greater China IMMC will acquire the Conference Grant to travel to Hong Kong in early May 2016 for presentation and defense of their solution paper. Best two papers from each region, totally eight, will enter into the international round of judging by the IMMC International Expert Panel.

IMMC 2016 Instructions and Rules

To participate in IMMC, your team members could come from the same class or across classes or grades; however, all members of each team should come from the same school and must have a teacher advisor from that school. IMMC 2016 is open to all secondary schools and has no limit to the number of teams that your school could register.


Contest Rules


  1. A team may consist of up to four students, in grade 12 or below, enrolled at the same school. A school can have more than one teams registered.
  2. The contest for Hong Kong, Macau, Taiwan and Mainland teams runs between 7:00 a.m. (GMT/UTC +8) Thursday, March 17th, 2016 and 7:00 p.m. (GMT/UTC +8) Wednesday, April 6th,2016.
  3. Each team will decide on a consecutive 5 day period between March 17 - April 6 to work on the contest problem. For example, the contest for your team could be from 8:00 a.m. (GMT/UTC +8) on Thursday, March 24 until 8:00 a.m. (GMT/UTC +8) on Tuesday, March 29. Your teams' contest ends upon completion of the 5 day period.
  4. Teams will be given access to the modeling problem. You must obtain and use your control number and password to participate in IMMC 2016. Teams must log on to the IMMC Greater China website at the beginning of their 5 day contest period (not before 7:01 a.m. (GMT/UTC +8) Thursday, March 17th 2016) to receive the contest problem.
  5. Teacher advisors must ensure that no alterations of any form are made after the end of your 5 day period or no later 7:00 p.m. (GMT/UTC +8) Wednesday, April 6th,2016. Papers must be collected from students at this time to be emailed in PDF format to the designated account for judging by Greater China Expert Panel. DO NOT include programs or software with your email as they will not be used in the judging process. Limit one solution per email. The names of the students, advisor, or institution should NOT appear on any page of the electronic solution. Page 1 of the teams electronic solution should be the team summary.
  6. All emailed papers must be received no later than 9:00 p.m. (GMT/UTC +8) Wednesday, April 6th,2016.
  7. A signed Parental/Guardian Authorization form must be included for each participating student. The singed Authorization Form should be sent in PDF format together with the solution paper. Schools should keep the original copy of each for their records.
  8. All accommodations relative to learning conditions for individual students would follow the accommodations used as part of the local school program in an affected student's daily learning. If specialized staff is required, the school bears the responsibility for providing any specialized assistance as required by law. If such accommodations are required for a student participating, the school should detail them and the extent to which they were utilized as part of the IM2C activities.


Your Team(s) Online:


Each team will be assigned a control number through email notice. 
Important! 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. Read the rules and guideline carefully and go to the IMMC website at www.immchallenge.org and review Sample Problems to prepare your students. It is both legitimate and desirable to coach or otherwise prepare your team(s).
  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.
  3. 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 IMMC 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 SIGNED 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 problems will become available at 7:00 a.m. (GMT/UTC +8) Thursday, March 17th, 2016. When teams are ready to compete, the team advisor must login to view the problems. Once logged in look for the *VIEW PROBLEMS* link which will become active at 7:00 a.m. (GMT/UTC +8) Thursday, March 17th, 2016. Once you login and view the problems we recommend that you print out a copy for your students.
  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' teacher 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 IMMC judges are primarily interested in a teams' approach and methods.
  5. Papers must be typed and in English. NOTE: teams may submit their solutions by email in Chinese or their native language at the end of the 5-day period, as long as the English language translation is submitted by April 6, 2016. The English paper MUST be a direct translation with NO additional mathematical work done on the problem after the non-English submission.
  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 summary is a very important part of your IMMC 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.
  7. The solution must consist entirely of written text and possibly figures, charts, or other written material, on paper 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 # 321 page 8 of 18.
  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:

    • Conciseness and organization are extremely important. Key statements should present major ideas and results.
    • Present a clarification or restatement of the problem as appropriate.
    • Present a clear exposition of all variables, assumptions, and hypotheses.
    • Present an analysis of the problem, motivating or justifying the modeling to be used.
    • Include a design of the model. Discuss how the model could be tested.
    • Discuss any apparent strengths or weaknesses to your model or approach.
    • Incorporate lengthy derivations, computations, or illustrative examples in appendices. Summarize these in the main report. Results must be explicitly stated in the body of the report. 


Submitting a Solution Paper


  1. Teams must end all work on the Solution Paper at the end of the team's consecutive 5 day period, or by 7:00 p.m. (GMT/UTC +8) Wednesday, April 6th,2016.
  2. Send an electronic copy of the Solution Paper in PDF format by email:

    2-1. Each team is required to submit an electronic copy of its solution paper by email to the designated address.

    a. Your email MUST be received no later than 9:00 p.m. (GMT/UTC +8) Wednesday, April 6th,2016.

    b. Failure by a team to submit a solution via email by 9:00 p.m. (GMT/UTC +8) Wednesday, April 6th, 2016 will constitutes a violation of the contest rules and will result in that team's disqualification.

    c. If Chinese version is submitted first and English translated copy is submitted on or before April 6th, 2016, no further modifications, enhancements, additions, or improvements may be made to the team's solution paper after the initial email submission. Each team's electronic submission will be cross-checked for consistency with their Chinese and English submission. Any changes to the initial content will constitute a violation of the contest rules and may result in disqualification.

    2-2. In the subject line of your email write: IMMC and your team's control number. For example: Subject: IMMC 1111.

    2-3. Use your team's control number as the name of your file attachments.

    2-4. IMMC will accept only an Adobe PDF or Microsoft Word file of your solution. DO NOT include programs or software with your email as they will not be used in the judging process. Limit one solution per email. The names of the students, advisor, or institution should NOT appear on any page of the electronic solution. Page 1 of the teams electronic solution should be the team summary. *Note: The attachment must be less than 17MB.

  3. Have each student sign the Control Sheet, pledging that they have abided by the contest rules and instructions.

    To Summarize:

    a. Restatement Clarification of the Problem - state in your own words what you are going to do. Assumptions with Rationale/Justification - emphasize those assumptions that bear on the problem. List clearly all variables used in your model.
    Model Design and justification for type model used/developed.
    Model Testing and Sensitivity Analysis, including error analysis, etc.
    Discuss strengths and weakness to your model or approach.
    Provide algorithms in words, figures, or flow charts (as a step by step algorithmic approach) for all computer codes developed.

    b. Send electronic copy of Solution Paper by email: See #2 above for more details. 

    c. Include a copy of the Summary Sheet on top of the Solution Paper. Include also the Control Sheet in the Solution Paper submission.
    *So the paper order should be: Control Sheet on top followed by Summary Sheet followed by the Solution Paper.

  4. Be sure there is a signed Parental/Guardian Authorization form for each student and include it in the submission packet be emailed.
