This research was carried out with the aim of knowing and measuring student learning outcomes in science learning using the numbered head together (NHT) model in grade IV SD Negeri 044824 Kabanjahe House for the Academic Year 2021/2022. The location of this research is class IV SD Negeri 044824 Rumah Kabanjahe, totaling 20 students, and as the object of this research is to use the numbered head together (NHT) model in science subjects with the subject of plant parts and their functions. This type of research is Classroom Action Research (CAR), using two cycles in the form of teacher and student activity observation
sheets and multiple choice test questions. From the results of the first cycle research, the results of the implementation of learning on teacher activities with a percentage of 60.5% and the implementation of learning on student activities got a score of 62 while the individual mastery of students who completed their studies were 11 students out of 20 students and those who did not complete 9 students, while classical mastery learning in the first cycle is 55% and
