The third stage in Piaget's theory of cognitive development (ages 7-11) where children can think logically about concrete objects and events but struggle with abstract concepts. Children develop the ability to perform mental operations on tangible things they can see or manipulate.
Named by Jean Piaget in the 1940s, combining 'concrete' from Latin 'concretus' (grown together, solid) and 'operational' referring to mental operations or logical thinking processes. The term reflects children's ability to operate mentally on real, physical objects.
Kids in this stage can finally understand that squishing a ball of clay doesn't create more clay - but ask them about hypothetical situations like 'what if gravity worked backwards?' and they're stumped! Their logic is literally grounded in the physical world.
