Which Piaget concept describes understanding that quantity remains the same despite changes in shape?

• A. Sensorimotor
• B. Preoperational
• C. Conservation
• D. Formal Operational

Answer: (C)

Conservation is the ability to recognize that quantity stays the same even when its shape or appearance changes. In Piaget’s theory, this skill develops during the concrete operational stage when children begin to think more logically and can use reversible thinking and decentering. For example, if you pour the same amount of water into a tall, skinny glass versus a short, wide one, a child who has grasped conservation understands the amount remains the same despite the different shapes. Earlier, in the preoperational stage, children often focus on what things look like (height or appearance) and may think the tall glass has more water. Later, in the formal operational stage, they can handle abstract reasoning, but conservation is specifically linked to concrete, logical thinking about quantity.
