Concrete Operational Cognition



The Concrete Operational stage of development is the third of Jean Piaget’s stages of cognitive development. Children are in this stage from ages 7-11: you should think grade-school aged kids. In this stage, children develop the principle of conservation. That is to say, these kids understand that a given amount of liquid is conserved when it is poured from one container into another container of a different size.

Key Points

  • Concrete Operational
    • Period: 7 - 11 years (grade school children)
    • Understands conservation 
      • E.g. The total amount of liquid is conserved when poured between two differently shaped cups
      • Can grasp concrete analogies/relations
    • Mathematics/Arithmetic competence develops

Can categorize objects (e.g. cars, trucks → automobiles)
