 The background of this study is the low mathematics learning outcome of IV grade students of SD
Negeri 015 Sungai Tonang with an average score of 61.95, subpar to the KKM (minimum criteria
of mastery) of the school, which was 70.00. This study aims to determine the increase in
mathematics learning outcomes of IV grade students in SD Negeri Sungai Tonang, North Kampar
