The concrete operational stage is the third in Piaget's theory of cognitive development. This stage lasts around seven to eleven years of age, and is characterised by the development of organized and rationale thinking. Piaget (1954a) considered the concrete stage a major turning point in the child's cognitive development, because it marks the beginning of logical or operational thought. The child is now mature enough to use logical thought or operations (i.e. rules) but can only apply logic to physical objects (hence concrete operational).
Children gain the abilities of conservation (number, area, volume, orientation) and reversibility. However, although children can solve problems in a logical fashion, they are typically not able to think abstractly or hypothetically.
