This study aims to determine the effect of giving rewards and reinforcement on student learning outcomes in mathematics in class IV at SD Negeri 106143 Sukamaju for the 2022/2023 academic year. In this study, researchers used quantitative methods. The population used was all students at SD Negeri 106143 Sukamaju with a sample of 31 students. Sampling using nonprobability sampling. The results of this study indicate that the results obtained from correlation test can be seen in the correlation coefficient of r (count) 0.689 ≥ r (table) 0.355, it can be concluded that the alternative hypothesis (Ha) is accepted, that is, there is a significant effect between reward and reinforcement on student learning outcomes at SD Negeri 106143 Sukamaju. It can also be seen from the results of the t-test where t (count)> t (table) is t (count) of 5.113 and t (table) of 2.042, then the hypothesis (Ha) is accepted. This shows that there is a significant positive effect between the provision of rewards and reinforcement and mathematics learning outcomes in class IV of SD Negeri 106143 Sukamaju for the 2022/2023 academic year.
