Ratio Rings can be used in the classroom to help students visualize the connection between fractions, decimals, percents, degrees, and time. Included are a 4 inch ring for each of the five area and 4 inch circles broken into halves, thirds, fourths, fifths, sixths, eighths, ninths, tenths, and twelfths. The kit can be used to convert between the different areas, or to add and subtract fractions. It can also be used to simplify fractions or to create equivalent fractions.
