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.
