will learn how to use mapping diagrams (MD) to make sense of functions
and relate these to materials taught in calculus and in preparing for
A mapping diagram is an alternative to a Cartesian graph that visualizes
a function using parallel axes. Like a table, it can present finite
date, but also can be used dynamically with technology.
An overview of basic function concepts with MD’s will begin the session using worksheets and GeoGebra.
Connections of MD's to key concepts in studying calculus and preparing
to study calculus will follow showing the power of MD’s to make sense of
function concepts of measurement, rate, composition, and approximation
related to calculus.
Background and examples will be available at Mapping Diagrams from
A(lgebra) B(asics) to C(alculus) and D(ifferential) E(quation)s. A
