Colourful Magnetic Fraction Circles 26 cm, Demonstration Set

The set includes 9 colour circles, each 26 cm diameter, made of colourful magnetic foil. Each of the 9 circles is of a different colour and 8 of them are divided into a various number of parts showing in such a way 1 whole (1/1) and fractions 1/2, 1/3, 1/4, 1/5, 1/6, 1/8, 1/10 and 1/12.
