The fraction circles are offered to the child who is already familiar with the numbers 1 to 10 and easily lend themselves to giving a sensory impression of fractions, since the first circle has a whole interlock, but the others subsequently contain the circle divided into 2, 3, 4, 5, 6, 7, 8, 9 and 10 equal parts. They also introduce the reading and writing of fractions; their use makes it possible above all to explore at a sensory level the equivalences between fractions and to introduce their operations.
