       This research is motivated by the lack of communication skills and learning outcomes in the learning of mathematics of students of class V in SD Plus Marhamah Tabing Padang. The purposes of this research are to describe the improvement of: (1) communication ability of class V students in presenting mathematical statement, (2) communication ability of student in presenting allegation, (3) communication ability of class V students in drawing conclusion, and (4) cognitive learning outcomes of class V students in mathematics learning. The theories used as reference are about communication by Suparno, (2001: 135), about learning outcomes by Hamid (2010:175) and about discussion by Suryobroto (in Trianto, 2010: 122).
