In which stage of Piaget's theory do children learn to think logically about concrete events?

The Concrete Operational Stage is the correct answer because it marks a significant development in cognitive abilities as children progress in their thinking skills, typically occurring between the ages of 7 and 11. During this stage, children become capable of logical thought processes and can perform operations on concrete objects and events. They begin to understand the concept of conservation, meaning they recognize that quantities do not change when their shape or arrangement does. This includes the ability to classify and categorize objects more effectively.

In contrast, the other stages describe different levels of cognitive development. The Preoperational Stage, which occurs from around 2 to 7 years, is characterized by symbolic thinking and egocentrism, where children have difficulty understanding others' perspectives. The Sensorimotor Stage, covering the first two years of life, involves learning through sensory experiences and motor actions, without the ability to think logically about events. Lastly, the Formal Operational Stage follows the Concrete Operational Stage, beginning around age 12, where individuals develop the ability to think abstractly and logically about hypothetical situations and concepts.
