3-Act Math Modeling

The enVision 6-12 Mathematical Modeling in 3 Acts lessons present students with the opportunity to model conceptual thinking in real-world situations. Lessons require students to identify essential variables, formulate models from those variables, perform operations using the model, interpret the results of those operations, and validate the conclusions of those results. It all takes place within three simple acts.
