Which stage of cognitive development, according to Piaget, involves children learning to think logically about concrete events?

According to Jean Piaget, the stage of cognitive development where children begin to think logically about concrete events is called the Concrete Operational Stage. This stage typically occurs between the ages of 7 and 11 years. During this time, children start to understand the concepts of conservation, meaning they can recognize that the quantity of something remains the same even if its shape changes. For example, if you pour water from a short, wide glass into a tall, thin glass, a child in this stage will understand that the amount of water is still the same, even though it looks different. This logical thinking helps children solve problems and understand the world around them more effectively.
