<![CDATA[This research was motivated by the low mathematics learning outcomes of 3A grade students at SDN Ciketing Udik 2, as shown by only 8 (32%) students reaching the Minimum Completeness Criteria (KKM) on multiplication and division operations material. This low achievement was influenced by students' lack of interest, disparities in understanding among students, and the limited variety of learning models used by the teacher. This research aims to improve students' mathematics learning outcomes through the application of the Numbered Heads Together (NHT) learning model based on peer tutoring. The method used was Classroom Action Research (CAR), carried out over two cycles with the stages of pre-cycle, planning, implementation of action, observation, and reflection. The research subjects were 25 students of class 3A at SDN Ciketing Udik 2 in the 2025/2026 academic year. Data were collected through teacher observation techniques and students' cognitive learning outcome tests in the form of questions, with a success indicator of 85%. The results of the research showed an improvement in each cycle. In cycle 1, 21 students (84%) reached the KKM with a class average score of 80, increasing in cycle 2 to 24 students (96%) reaching the KKM with an average of 90. Based on these results, it can be concluded that the application of the Numbered Heads Together (NHT) learning model based on peer tutoring was effective in improving students' mathematics learning outcomes in multiplication and division material by 64% in class 3A at SDN Ciketing Udik 2.]]>
