摘要：In this case study, it is aimed to define and explain the perceptions and teaching activities of primary school teachers about mathematical estimation skill. For this purpose, three primary school teachers working in a public school were included in this study. Convenient and criterion sampling methods, which are purposeful sampling methods, were used to determine the participants. The data was obtained by using the observation, interview and document review methods together. Within the scope of these methods, semi-structured observation and interview forms prepared by using the literature, expert opinion and pilot data were used in this research. The data were analyzed using a qualitative data analysis program. As a result of the study, it has been concluded that the teachers attach importance to mathematical estimation skill, however, they have defective perceptions and practices regarding the meaning and teaching of this skill.
