This is evidenced by the fact that only 13 students (48.14%) of the 27 students were able to achieve the KKM score. The purpose of this study was to improve the results of learning mathematics in circle material by applying the STAD cooperative model to class VI students at SDN 002 Bagan Besar Dumai.
