#NewYearsResolution: Learn something new daily! Maybe even math?
Wooden blocks and rods have long been used to teach young children about numbers and basic arithmetic. This set was designed by Emile-Georges Cuisenaire (1891-1976), a Belgian schoolteacher.
After the Soviet Union launched the Sputnik satellite in 1957, better instruction in science and mathematics became a national priority in the U.S. Scientists, mathematicians, and educators introduced objects like Cuisenaire rods to communicate to students their enthusiasm for basic principles. This set was used by an American teacher in the South Pacific.
