Building Dynamic Fraction Bar Models with GeoGebra
Thomas Edmond Cooper — University of North Georgia
Abstract
In this article, the author demonstrates how GeoGebra can be used to build fraction bar models for conceptualizing equivalent fractions as well as addition, subtraction, multiplication, and division of fractions. Each construction uses checkboxes and input boxes to allow users to dynamically interact with the constructions and sequences of polygons to create the fraction bars.
