Fraction Bars
Fraction Bars are a type of mathematical manipulative, developed in the sixties by Albert B. Bennett, Jr.[1] They provide visual illustrations of mathematical operations with fractions[2] to gain better understanding of these operations.
A complete Deck of 49 Fraction Bars.
Overview
Fraction Bars for halves, thirds, fourths, fifths, sixths, tenths, and twelfths form a complete deck. These bars are a part-to-whole region model for teaching the basic concepts of fractions, equality, inequality, addition, subtraction, multiplication, division, and ratios. They are plastic coated so marking bars with water-base pens can be washed off. Fraction Bars are used for teaching fractions in schools and for preparing teachers.
