The description of Coral System Deck
This learning method has been developed by Juan Pedro Sánchez Márquez, psychologist and child teacher in deck format, and here we provide you with a digital version with a reduced price, which will help review without boredom, since this is just a game.
There are three difficulty levels adapted to different ages, in which operations are randomly generated, and in case of error it shows you the correct result.
