The purpose of this paper is to capture how children do cognitive activity in process of polishing up, and to see about possibility of buildup of metacognitive knowledge. In this paper, the research on teaching of metacognition was considered, and I checked to show that involvement of others (teacher and children) is desirable to do both during and after individual solving. Then, process of polishing up provided two categories: Stage of process of polishing up, individual activity in stage of process of polishing up. I considered cognitive activity in process of polishing up from aspects such as sender of information and receiver of information, and I tried to capture cognitive activities. In the result, I captured some cognitive activities of sender of information and receiver of information. It is cleared that children works metacognition for cognitive activity then buildup of metacognitive knowledge.
