The purpose of this study was to investigate the formation process of two intensive quantity concepts, velocity and thickness, in children. The subjects were 120 elementary school children from fourth to sixth grades, and 42 secondary school children in the first grade. Two kinds of comparison tasks were administered: Which one is faster between two objects? or Which one is thicker between the two? Moreover, three kinds of logical operation tasks were administered. The results showed t hat the concept formation of velocity preceded that of thickness, that in this process there were four stages which progressed as getting older, and also that some errors were caused by some imperfectness of logical operation. Those stages were especially expressed by some typical patterns of strategies, and errors on each stage were represented by some specific strategies.
