This study uses action research. It was conducted in two cycles. The subjects studied were students of class XI IPA SMA An-Naas Pekanbaru with the number of 20 people comprising from 6 male students and 14 female students. Students in the class are heterogeneous in terms of academic and gender. The activity and students learning outcomes data were gained by collecting activity data by using observation sheet and daily test. Analysis of the data used is descriptive statistical analysis that describes the activities of teacher and students, analysis of learning outcomes and succesful measurements. The results in the first cycle found that the percentage of students who achieve KKM is 20% and the second cycle was 45%, which increased the percentage of prior actions that only 10%, and the award based on the first cycle of two teams awarded a great team and three teams awarded the super team, while in the second cycle of three teams awarded great team and two teams awarded the super team. The conclusion of the study showed that the implementing cooperative learning model of numbered heads together structural approach could improving mathematics learning outcomes of students
