Water in the Tub: A Review of Functions and their Behavior (ARC)

Michael Hardy, Southeastern Oklahoma State University
Deborah Moore-Russo, University of Oklahoma

In this activity students are presented with an applied scenario of water level in a tub and asked to complete a graph of the situation considering appropriate units of measure for a piecewise function. While engaging in this low floor-high ceiling activity, students are applying the ideas of quantification, selecting appropriate units of measure (for height and time), and using covariational reasoning to represent the context graphically.
