The formulation of the problems in this study are: (1) is there any effect of the Make a Match model on the mathematics learning outcomes of SMP Harapan Mekar Medan students. (2) what percentage of the influence of the Make a Match learning model on the mathematics learning outcomes of SMP Harapan Mekar Medan students. The aims of this study were: (1) to determine the effect of using the Make a Match learning model on the mathematics learning outcomes of Harapan Private Middle School students. (2) to find out what percentage of the influence of the make a match model on student learning outcomes at SMP Harapan Mekar Medan. The population and sample in this study were students of the Experiment class as class VII A and the control class as class VII B at Harapan Mekar Middle School Medan, totaling 20 people, the Experiment class where there were 13 male students and 7 female students and the Control class totaling 20 people. with 7 male students and 13 female students.
