MACHINE TRANSLATION (not authorised yet)

Mathematical domain supporting and consolidating the learning of decimal fractions, in this case their subtraction. The set contains 26 plastic domino tiles, each side has an engraved decimal fraction on one side and the subtraction action on the other side. The game is to add a fraction or subtraction action of the same value to each domino cube, e.g. "15,20" and "33,33-18,13". The tiles are made in the original way: from smooth plastic with rounded corners, and the fractions are not printed but engraved, so dominoes can serve generations of players (the inscriptions do not clash and are unbreakable). Dimensions of each tile: 8x4 cm, rounded corners, total 26 tiles. A great way to learn through play.
