At what age range does the concrete operational stage of Piaget’s theory typically occur?

The concrete operational stage of Piaget's cognitive development theory typically occurs between the ages of 7 and 11 years. During this stage, children begin to think logically about concrete events. They can perform operations on tangible objects and understand the concept of conservation—that is, the understanding that quantity doesn't change despite changes in shape or arrangement. This stage marks a significant shift from the preoperational stage, where thinking is more intuitive and less logical.

Children in the concrete operational stage are able to classify objects, understand the order of operations, and can think about the perspective of others more effectively than in earlier stages. These developments lay the groundwork for more complex and abstract reasoning that will emerge in the subsequent formal operational stage, which begins around age 11. Therefore, the answer accurately reflects the age range associated with this critical stage of cognitive development.
