Cuisenaire rods are a versatile mathematical manipulative used in elementary school as well as other levels of learning and even with adults. They are used to teach a wide variety of mathematical topics such as the basic four operations, fractions, area, volume, square roots, solving simple equations, systems of equations, and even quadratic equations.The rods ( reglettes in the original French) are named after their inventor, Georges Cuisenaire (1891-1976), a Belgian primary school teacher, who published a book on their use in 1952 called Les nombres en couleurs. The use of rods for both mathematics and language teaching was developed and popularised by Caleb Gattegno in many countries around the world.
