The purpose of this treatise was to develop elementary school mathematics lessons that foster statistical problem-solving skills. In Japan, statistical problem-solving is performed using the PPDAC cycle, which is carried out from the 5th grade, but overseas, statistical education linked to probability is provided from the lower grades of elementary school. In Japan, we also developed learning materials using rock-paper-scissors play, which is a phenomenon familiar to children, and put it into practice in the third grade. in order to develop the ability to solve statistical problems from the lower grades. As a result of protocol analysis and descriptive analysis of children, it was found this learning materials was generally effective. This suggests that there is a possibility of developing statistical problem-solving skills from the lower grades.
