M3 Challenge

What is the M3 Challenge?

Moody's Mega Math Challenge is a mathematical modeling contest for high school students sponsored by The Moody's Foundation and organized by SIAM. The M3 Challenge spotlights applied mathematics as a powerful problem-solving tool, as a viable and exciting profession, and as a vital contributor to advances in an increasingly technical society. The contest introduces high school students to applied mathematics by giving them an opportunity to work in teams to tackle a real-world problem under time and resource constraints akin to those faced by industrial applied mathematicians.

What is Math Modeling?

A math model is a representation of a system or scenario that is used to gain a qualitative or quantitative understanding of some real-world problems and to predict future behavior. Used in a variety of scientific disciplines, models are abstractions of reality, and can lead to scientific advances, provide the foundation for new discoveries, and help leaders make informed decisions.

The 2014 Problem

Lunch Crunch: Can Delicious be Affordable and Nutritious?

This problem asks teams to determine a student's caloric requirements based on his or her individual attributes, assess the percentage of U.S. students who meet the definition of an "average" student, and develop a budget-friendly lunch plan to satisfy nutritional standards and students' palates.
