This study explored the development, validation, and effectiveness of gamified-based-strategies in teaching the union and intersection of events among Grade 10 students at Kasiglahan Village National High School. Utilizing a mixed methods approach with a sequential explanatory design, the research combined quantitative analysis through pretest and posttest evaluations and qualitative feedback from student interviews. The study involved 120 students divided into one control and two experimental groups. The control group received conventional instruction, while the experimental groups engaged in gamified activities incorporating competition, badges, and interactive games. Results indicated that students in the gamified groups demonstrated significantly higher posttest scores and deeper conceptual understanding than those in the control group. The findings were statistically significant, confirming the effectiveness of gamification in enhancing academic performance, engagement, and motivation. Qualitative feedback supported these results, highlighting improved participation, enjoyment, and clarity in learning abstract mathematical concepts. The study concludes that gamified strategies provide a valuable instructional approach to improve comprehension and student outcomes in mathematics, particularly in teaching union and intersection of events.
