This study primarily aimed to determine if additional subjects in Mathematics in Senior High School could improve learners’ performance. A total of 455 Grade 11 and 226 Grade 12 learners from the eight (8) senior high schools in the division participated in this study. This research used pretest/posttest quasi-experimental design. Data retrieved were analyzed primarily using frequency counts, mean, standard deviation and paired t-test. This study found that the level of performance of the majority of the learners increased after the implementation of the intervention. Furthermore, there was a significant difference in the performance of Grade 11 and Grade 12 learners before and after the intervention. For intervention adoption, this study recommends that Geometry and Trigonometry should be offered as an add on subjects in senior high school across all strands. Thus, there is a need for the DepEd Central Office Curriculum and Instruction Division to revisit the K to 12 Curriculum for the incorporation of these subjects.
