Abstract:
This research purposed to increase mathematics learning outcome of students on the class V-C SD
Negeri 161 Pekanbaru by applying Bruner Theory. Subject of this research are students on the
class V-C SD Negeri 161 Pekanbaru with amount 39 people, consist of 21 male students and 18
female students. The research is Classroom Action Research, consist of three cycles. Cycle I
