Cuisenaire rods illustrating the factors of ten A demonstration the first pair of amicable numbers, (220,284). Cuisenaire rods are mathematics learning aids for pupils that provide an interactive, hands-on [1] way to explore mathematics and learn mathematical concepts, such as the four basic arithmetical operations, working with fractions and finding divisors.
The silent way makes use of specialized teaching materials: colored Cuisenaire rods, the sound-color chart, word charts, and Fidel charts. The Cuisenaire rods are wooden, and come in ten different lengths, but identical cross-section; each length has its own assigned color. [24] The rods are used in a wide variety of situations in the classroom.
Here, Cuisenaire rods are used, particularly with beginners, to create visible and tangible situations from which the students can induce the structures of the language. The silence of the teacher both gives the students room to explore the language and frees the teacher to observe the students.
Demonstration with Cuisenaire rods of the amicability of the pair of numbers (220,284), the first of the series.. In mathematics, the amicable numbers are two different natural numbers related in such a way that the sum of the proper divisors of each is equal to the other number.
Georges Cuisenaire (1891–1975), also known as Emile-Georges Cuisenaire, [1] was a Belgian teacher who invented Cuisenaire rods, a mathematics teaching aid. Life [ edit ]
Demonstration, with Cuisenaire rods, of the first four highly composite numbers: 1, 2, 4, 6. A highly composite number is a positive integer that has more divisors than all smaller positive integers. A related concept is that of a largely composite number, a positive integer that has at least as many divisors as all smaller positive integers.
