Arithmetic Teaching ApparatusBlocks and Bars
In the early twentieth century, the Italian educator Maria Montessori introduced a variety of apparatus for introducing young children to ideas about numbers and arithmetic. In the mid-twentieth century, the German-born American teacher Catherine Stern and the Belgian educator Georges Cuisenaire developed systems of teaching about numbers and arithmetic with wooden blocks.
"Arithmetic Teaching Apparatus - Blocks and Bars" showing 1 items.
- Wooden blocks and rods have long been used to teach young children about numbers and basic arithmetic. These are such a tool. They vary in length from 1 cm. to 10 cm., representing the numbers from 1 to 10. All rods of a given length are the same color. They are stored in a cloth bag. This set was designed by Emile-Georges Cuisenaire (1891-1976), a Belgian schoolteacher. Cuisenaire published an account of his rods in French in 1953 and attracted the attention of the Egyptian-born educator Caleb Gattegno (1910-1988).
- 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.
