Is a quarter note always one-quarter of the whole?

The aim of our work was to find how to bring fractions to pupils without bringing usual negative attitude and later lack of understanding. We link fractions to the concept of musical rhythm. In our activity children create their own rhythms, having a choice of representation - fulfilment of the circle, musical notes and number. Alternating three forms of fractions representation during rhythm composition, children are offered a possibility to switch from the fraction as a part to the fraction as a proportion and as a number. Our make-your-own-rhythm game as a part of a classroom discussion can lead further to other mathematical areas, e.g. combinatorics, equations, infinite series or statistics. Fractions could affiliate to the everyday of children as well as become one new step to the unknown heights of higher mathematics.
