title="Caleb Gattegno">Caleb Gattegno</a> popularised this set of coloured number rods created by <a href="/wiki/Georges_Cuisenaire" title="Georges Cuisenaire">Georges Cuisenaire</a> (1891–1975), a <a

"Georges Cuisenaire showed in the early 1950s that pupils who had been taught traditionally, and were rated 'weak', took huge strides when they shifted to using the material. They became 'very good' at traditional arithmetic when they were allowed to manipulate the rods."<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cuisenaire_rods&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The educationalists <a href="/wiki/Maria_Montessori" title="Maria Montessori">Maria Montessori</a> and <a href="/wiki/Friedrich_Fr%C3%B6bel" title="Friedrich Fröbel">Friedrich Fröbel</a> had used rods to represent numbers,<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> but it was Georges Cuisenaire who introduced the rods that were to be used across the world from the 1950s onwards. In 1952, he published <i>Les nombres en couleurs</i>, Numbers in Color, which outlined their use. Cuisenaire, a violin player, taught music as well as arithmetic in the primary school in <a href="/wiki/Thuin" title="Thuin">Thuin</a>. He wondered why children found it easy and enjoyable to pick up a tune and yet found mathematics neither easy nor enjoyable. These comparisons with music and its representation led Cuisenaire to experiment in 1931 with a set of ten rods sawn out of wood, with lengths from 1 cm (0.4 in) to 10 cm (4 in). He painted each length of rod a different colour and began to use these in his teaching of arithmetic. The invention remained almost unknown outside the village of Thuin for about 23 years until, in April 1953, British mathematician and mathematics education specialist <a href="/wiki/Caleb_Gattegno" title="Caleb Gattegno">Caleb Gattegno</a> was invited to see pupils using the rods in Thuin. At this point he had already founded the <a rel="nofollow" class="external text" href="https://web.archive.org/web/20060515004941/http://www.irdp.ch/cieaem/">International Commission for the Study and Improvement of Mathematics Education (CIEAEM)</a> and the <a href="/wiki/Association_of_Teachers_of_Mathematics" title="Association of Teachers of Mathematics">Association of Teachers of Mathematics</a>, but this marked a turning point in his understanding: </p> <blockquote><p>Then, Cuisenaire took us to a table in one corner of the room where pupils were standing round a pile of colored sticks and doing sums which seemed to me to be unusually hard for children of that age. At this sight, all other impressions of the surrounding vanished, to be replaced by a growing excitement. After listening to Cuisenaire asking his first and second grade pupils questions and hearing their answers immediately and with complete self-assurance and accuracy, the excitement then turned into irrepressible enthusiasm and a sense of illumination.<sup id="cite_ref-FTTOM3_6-0" class="reference"><a href="#cite_note-FTTOM3-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup></p></blockquote> <p>Gattegno named the rods "Cuisenaire rods" and began trialing and popularizing them. Seeing that the rods allowed pupils "to expand on their latent mathematical abilities in a creative and enjoyable fashion", Gattegno's pedagogy shifted radically as he began to stand back and allow pupils to take a leading role: </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Cuisenaire_rod_experimentation.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Cuisenaire_rod_experimentation.jpg/220px-Cuisenaire_rod_experimentation.jpg" decoding="async" width="220" height="149" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Cuisenaire_rod_experimentation.jpg/330px-Cuisenaire_rod_experimentation.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Cuisenaire_rod_experimentation.jpg/440px-Cuisenaire_rod_experimentation.jpg 2x" data-file-width="4480" data-file-height="3032" /></a><figcaption>Example of Cuisenaire rods</figcaption></figure> <blockquote><p>Cuisenaire's gift of the rods led me to teach by non-interference making it necessary to watch and listen for the signs of truth that are made, but rarely recognized.<sup id="cite_ref-FTTOM3_6-1" class="reference"><a href="#cite_note-FTTOM3-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup></p></blockquote> <p>While the material has found an important place in myriad teacher-centered lessons, Gattegno's <a href="/wiki/Student-centred_learning" class="mw-redirect" title="Student-centred learning">student-centered</a> practice also inspired a number of educators. The French-Canadian educator Madeleine Goutard in her 1963 <i>Mathematics and Children</i>, wrote: </p> <blockquote><p>The teacher is not the person who teaches him what he does not know.

It seemed to me at first that we could use them as devices for packing in recipes much faster than before, and many teachers seem to be using them this way. But this is a great mistake. What we ought to do is use these materials to enable children to make for themselves, out of their own experience and discoveries, a solid and growing understanding of the ways in which numbers and the operations of arithmetic work. Our aim must be to build soundly, and if this means that we must build more slowly, so be it.

The colors of non-prime numbers are obtained by mixing the colors associated with their factors – this is the key concept.
