Answer:
Tommy's way of thinking is qualitatively different from that of Willie.
Step-by-step explanation:
Dad tells five-year-old Willie to "get all your stuff off the floor and clean up your room." Willie piles all his toys on a shelf in a haphazard way. When 8-year-old Tommy gets the same instructions, he puts all his sports-toys in one place, his action figures in another, and his books in a third place. According to Piaget, Tommy's ways of approaching this is different from Willie's because Tommy's way of thinking is qualitatively different from that of Willie.
