Fraction BarsŪ were created by Dr. Albert B. Bennett, Jr. and Dr. Patricia Davidson. Fraction BarsŪ have long set the standard for a manipulative approach to teaching fractions. Fraction BarsŪ are the ONLY fraction manipulative that can be used to compare parts and show the relative differences. Fraction BarsŪ products provide a complete program that can be correlated to any textbook or used as a stand alone program. Fraction BarsŪ meet the NCTM standards for teaching mathematics and help teachers develop communication in math competency through pictorial models and various student activities.
