Fraction Bar Set is Colorful, These Fraction Bars come in a plastic tray. The total of 51 solid plastic tiles represent a whole, halves, thirds, fourths, fifths, sixths, eighths, tenths, and twelfths. Fractional values appear on the front of the tiles and there percentage at back side. Fraction bars is a fun way to teach children the meaning of and how to use fractions. The different sections of the bar equal one part of the fraction and the whole bar represents 1. It is easy to demonstrate to children the difference between the numerator (the number on the top of a fraction) and the denominator (the number on the bottom), and to then show them the relationship between the two as separated by the vinculum, or the dividing line. You can use the bars as standalone games or as part of your lesson plan.
