古氏积木(Cuisenaire rods)

古氏积木(Cuisenaire rods)由一位比利时的小学老师George Cuisenaire（乔治．古辛纳）(1891-1976)所研发，Cuisenaire将彩色古氏积木应用在数学教学上，其学生在学数学时因有了积木的辅助，更容易了解老师所教授的东西，并能在此种教学法中得到乐趣。在1952年时，Cuisenaire出版了积木的使用手册，说明积木的使用方法。

Cuisenaire rods are mathematics learning aids for students that provide a hands-on elementary school way to explore mathematics and learn mathematical concepts, such as the four basic arithmetical operations, working with fractions and finding divisors. In the early 1950s, Caleb Gattegno popularised this set of coloured number rods created by the Belgian primary school teacher Georges Cuisenaire (1891-1975), who called the rods réglettes.
