What are Cuisenaire® Rods?
Cuisenaire® Rods are a collection of rectangular rods of 10 lengths and 10 colours, each colour corresponding to a different length. The smallest rod, a white centimetre cube, is 1cm long; the longest, the orange is 10 cm.
One set contains 74 rods: 4 each of the orange (σ), blue (e), brown (n), black (k), dark green (d), and yellow (y); 6 purple (p); 10 light green (g); 12 red ®; and 22 white (w). One aspect of the rods is that, when they are arranged in order of length in a pattern commonly called a “staircase,” each rod differs from the next by 1cm, the length of the shortest rod, the white.
