This work has the aim of investigating, in a psychogenetic context, the possibilities of a game of rules to be introduced in the psycho-pedagogical diagnosis with the purpose of evaluating the construction of classification awareness. Forty students of both genders with ages between 4 and 17 years old attending primary (kindergarten and 1st grade) and elementary (3rd to 8th grade) public schools have participated on this research, 10 in each developing level: figural collection, non-figural collection, hierarchical inclusion of classes and logical thinking. Spontaneous classification tests were applied, along with hierarchical inclusion of classes, matching cards of various colors and four matches with the game "Find out the Animal". The results point out that the game utilized was effective to help on psycho-pedagogical diagnosis for the classification.
