Rational Number Project
Elementary School Mathematics

As of July 2007 no studies of Rational Number Project were found that fell within the scope of the Elementary School Mathematics review protocol and met WWC design standards. Therefore, the WWC is unable to draw any research based conclusions about the effectiveness or ineffectiveness of Rational Number Project to improve outcomes in this area.
The Rational Number Project was a cooperative multi-university research and development project funded by the National Science Foundation (NSF) from 1979-2002 (with the exception of 1983-84). One of the results of this project is a curriculum of lessons designed to introduce students in grades 4-8 to fractions, decimals, ratios, and measurement and meet the standards of the National Council of Teachers of Mathematics (NCTM). Lessons are conducted in large and small group settings, with daily hands-on activities involving manipulative kits. Along with a spiral-bound lesson book, colored tiles and pie piece shapes are among the manipulatives used to assist students in fraction operation and comprehension.
