Piaget proposed that around 7 years of age, children enter the concrete operational stage of cognitive development.
According to Piaget's theory of cognitive development, the third stage is the concrete operational stage. The development of systematic and logical thinking occurs during this seven to eleven-year-old age range.
Because it heralds the onset of logical or operational thought, Piaget (1954a) saw the concrete stage as a crucial turning point in the child's cognitive development. The youngster can now utilize logical reasoning or operations (i.e., rules), but they can only be used with physical objects (hence concrete operational stage). Children develop the skills of transitivity, reversibility, seriation, conservation (number, area, volume, orientation), and reversibility. Children are often not able to think abstractly or hypothetically, despite the fact that they can solve issues logically.
