Which Piaget stage describes logical thinking about concrete events in school-age children?

• A. Concrete operational
• B. Sensorimotor
• C. Preoperational
• D. Formal operational

Answer: (A)

Piaget's concrete operational stage marks the emergence of logical thinking about concrete events during the school-age years. Around ages 7 to 11, children develop mental operations that let them reason logically about tangible problems they can see or manipulate. They understand conservation (recognizing that quantity remains the same despite changes in appearance), grasp reversibility (recognizing that actions can be reversed in thought), and can classify and seriate objects by size or other properties. Their thinking becomes less egocentric and more organized, but it remains tied to concrete, observable experiences. Abstract or hypothetical reasoning, which appears later in the formal operational stage, is not yet mature at this point.
