Introducing Dynamic Number is a three-year research and development project to extend and operationalize research in number, operations, and early algebra and to address the challenge of assuring all students the opportunity to learn significant mathematics content.  It is funded by a grant from the National Science Foundation to KCP Technologies, the developers of The Geometer’s Sketchpad software, and The University of Georgia. Through the development of software tools that allow for the direct manipulation and construction of integers, fractions, decimals, and variables, the Introducing Dynamic Number project aims to produce powerful, classroom-tested software tools and accompanying curricula to address these pivotal concepts in early and middle-grades mathematics. Research and evaluation activities are being led by Dr. John Olive at UGA. Dr. Leslie P. Steffe is a consultant to the Project and Mr. Doug Griffin is a research assistant and school liaison with our cooperating school in Oglethorpe County. The project director is Dr. Daniel Scher with KCP Technologies. The project is being implemented in schools in Georgia, New York, Pennsylvania, California and Croatia.
