1 + 2 = 3. White + Red = Green!

In December 1952 Georges Cuisenaire, a native of Belgium, published a thin booklet called "Les Nombres en Couleurs." In less than 15 years his "reglettes" were in use to teach mathematics in schools in over one hundred countries throughout the world.

Cuisenaire Rods are small pieces of wood measuring between one and ten centimetres in length. They are coloured such that all the rods of the same length are the same colour. Physically the rods behave in the way numbers behave, providing the learners with an algebraic model for the study of mathematics.

Finally, for the curious, here is the sequence of colours from 1 to 10: white, red, light green, pink, yellow, dark green, black, brown, blue, orange.
