The Fractions Microworld is for exploring the properties of the rational numbers, interacting with a graphic model based on the Thalete's theorem. The Fractions Microworld allows: to construct fractions on the numbers' half line and to execute operations with fractions by exploiting geometrical properties, which are incorporated in the graphic model and based on the partition concept.

The representations realized in the Fractions Microworld can be copied to be pasted on the Solution Sheet.
