Algebricks are colored rods or varying lengths that make mathematical concepts visible and tangible.They are also used in language learning to create situations for students to discuss in the target language.
Our mathematics textbooks start with free play, transition to making trains, and lead into topics such as division of fractions and Pythagorean theorem. Students don't need to trust the teacher's answer, or the results of an abstract formula, because the results of the mathematical operations are easily seen and felt in the rods.
Dr. Caleb Gattegno's techniques for teaching mathematics were developed after meeting a Belgian schoolmaster named Georges Cuisenaire in 1953. Gattegno was inspired by Cuisenaire's invention of colorful rods of varying lengths. Rods of the same length had the same color, and could represent anything from musical notes to numbers. Eventually, Gattegno started the Cuisenaire Company promoting the use of the rods as a visible and tangible way for children to express mathematical ideas. Many people still refer to the rods, which we call Algebricks, as Cuisenaire Rods.
