Images of FDPRP A Cuisenaire rod fraction / factor / decimal / percentage wall: This wall shows the factors of ten: 1 x 10 2x5 5x2 10 x 1 Equivalent fractions are also easily demonstrated – e.g. 5/10 = ½ Similarly, decimals and percentages can be expressed – e.g. a red rod has 20% length of the orange rod. 3 is not a factor of 10, as shown here. However, the light green rod can be shown to be 3 /10 of the length of the orange rod. Ratios can be expressed using Cuisenaire: E.g. the ratio of the red rod to the light green rod is 2:3, ratio of light green to red is 3:2 Equivalent ratios can be demonstrated: The ratio of the pink to the dark green rod is 4:6, but this is equivalent to the ratio of red to light green.
