The hands-on activity will focus on the high school Number and Quantity domain of the Common Core, and in particular on complex numbers in polynomial equations. Participants will roll a ball on a piece of graph paper at a slant to form a parabola. A graphing calculator will be used to model the function and confirm real or complex solutions. The fundamental theorem of algebra will be demonstrated.
