Decreasing and increasing fractions are illustrated by decreasing and increasing shaded amounts of Fraction Bars. For decreasing amounts the patterns shows that the more equal parts for a bar the smaller the fraction for one of these parts, and that the fractions get closer and closer to zero. For increasing shaded amounts of bars, the fractions for the bars get closer and closer to 1. The Tower of Bars mat from the Fraction Bars materials has bars for fractions with denominators of 2 through 12. By shading the bars on this mat, many fraction patterns can be discovered. The video ends with a demonstration of the free interactive web game "Hitting Asteroids" from fractionbars.com.
