The National Library of Virtual Manipulatives is a three-year NSF supported project to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-8 emphasis). The project includes dissemination and extensive internal and external evaluation. For more information, please visit http://nlvm.usu.edu/en/nav/vlibrary.html.
Description
This interactive web-based manipulative illustrates the two-step process of adding proper fractions. The first step in adding fractions is to identify a common group name (denominator). Finding a common group name means separating two (or more) whole groups into the same number of parts.
