<![CDATA[The purpose of this study was to determine the effect of the use of multiplication bar media on the understanding of the concept of mathematical multiplication of fourth grade students of SDN 2 Lawe Hijo, Southeast Aceh Regency. The type of research used is quantitative with quasi experimental method. The research design used was Pretest-Posttest Control Group Design. Therefore, the population used was all grade IV students of SDN 2 Lawe Hijo totaling 56 students consisting of 2 classes, namely experimental and control classes. Sampling using random sampling technique so that class IVA was selected as the experimental class totaling 28 people and class IVB as the control class totaling 28 people.
