This research was conducted in grade 1 students with a total of 13 male students and 11 female students. Before the improvement was held there were only 14 students who had not been able to reach the KKM 65, in the first cycle students who achieved KKM became 20 students, and in the second cycle increased to 24 students or all students had reached the KKM.
