MACHINE TRANSLATION (not authorised yet)

Mathematical domain supporting and consolidating the learning of ordinary fractions, in this case their subtraction. The set contains 24 plastic domino plates, each side has an engraved ordinary fraction on one side and the subtraction of ordinary fractions on the other side. The game is to add a fraction or subtraction of the same value to each domino cube, e.g. "1/4" and "6/8 - 8/16". The tiles are made in the original way: from smooth plastic with rounded corners, and the fractions are not printed but engraved, so the dominoes can serve generations of players (the inscriptions do not clash and are unbreakable). Dimensions of each tile: 8x4 cm, rounded corners, total 24 tiles. A great way to learn through play.
