The study employed quasi – experimental research to investigate the effect of Acumetric Approach on students’ performance on Integers in Mathematics 6. The participants were two sections of Grade 6 students at Mabunao Elementary School, Barangay Mabunao, Panabo City, Phillipines. One section was assigned as control group, which was exposed to conventional approach with usual motivation and varied activities given in typical classroom teaching, while the other was the experimental group, which was exposed to Acumetric Approach, giving a game-based design repeated activities on non-digital mode, wherein the games were printed and instructions were provided. Pre-test and Post-test were administered prior and after experimentation. The pre-test results reflected that both groups had a low level of performance and no significant difference. After the post-test, both groups had increased their level of performance of which the control group developed from low to average level while the experimental group moved from low to mastery level. The post-test results had shown that there was a significant difference on their mean percentage score. Moreover, by controlling the Pre-test as covariate, the result significantly improved the performance level of the experimental group with a p-value of <0.05. Hence, the experimental group performed better than the control group. Thus, Acumetric Approach can improve the achievement of students in Mathematics.
