Wings of Ring 1000-FT 907

Fit these clear plastic rings around Fraction Circles to explore degrees, time, percent, and more!
These clear plastic rings fit around Fraction Circles to show the relationships among fractions, decimals, and percents (¼ = 0.25 = 25%); to demonstrate the equivalence of minutes and fractional parts of an hour (15 minutes = ¼ hour); and to express fractional parts of a circle in degrees (¼ of a circle =90°). Each of the five rings in the set is divided into equal intervals, contains a well-marked scale including a “0” to indicate a starting.
