concrete operation

the ability of a growing child to mentally represent items in the physical world and to understand the logical relations between them. Concrete operational children are, for example, able to understand the concept of class inclusion and to represent part–whole relations in the physical world correctly (e.g., to grasp that dogs are a subset of animals or houses are a subset of buildings).
