One step at a time! A seemingly linear relationship becomes an entirely new type of function. Young scholars build their understanding of step functions by completing a three-stage activity that incorporates multiple representations of the step function during nine problem scenarios. Learners create tables, graph, and write functions to model the step pattern.
