At what age range do children typically enter the concrete-operational stage?

Children typically enter the concrete-operational stage between the ages of 7 and 11 years. This developmental stage, as proposed by Jean Piaget, is characterized by the gradual emergence of logical thinking and the ability to grasp concrete concepts. During this phase, children begin to think logically about concrete events, understand the concept of conservation, and can categorize and organize objects based on multiple characteristics, such as size, shape, and color.

This cognitive development allows children to engage in problem-solving and reasoning that involves tangible objects, rather than abstract thinking. It signifies an important transition from the preoperational stage, where children's thinking is often influenced by their perceptions and lacks logical consistency.

In summary, the 7 to 11 years age range marks a significant period of cognitive development where children enhance their logical reasoning skills through hands-on experiences and the manipulation of physical objects.
