Modeling Scenarios: Levels 1, 2, and 3
Several examples of the types of problems you may be asked to solve in the M3 Challenge are presented here.
It is highly recommended that participants read and work through some problems at each level before moving on.
Level 1:
Modeling Scenarios [14K PDF]
This list is intended to give students a taste of some of the scenarios that may be presented as modeling problems in the M3 Challenge. This can be considered basic training material, designed to prompt targeted brainstorming.

These booklets detail modeling problems that remain relevant today despite being somewhat dated in appearance. These examples have considerable background data, which gives insight into the types of details that need to be considered when solving the Challenge problem. Remember that creativity and originality are highly valued characteristics of a winning solution—along with good quantitative and qualitative analysis.
