The purpose of this study is to evaluate the impact of the Mathema Tic-Tac-Toe intervention on students’ skills in solving polynomial problems. Specifically, the study aims to determine the significant difference between students’ pretest and post-test scores. A pre-experimental research design was utilized to assess the intervention’s effectiveness. Data were collected from 76 students in Grades 8 and 10 at Kapalong National High School, selected through purposive sampling. Pre-test and post-test assessments were used for data gathering. The findings revealed a substantial improvement in scores, with the mean percentage score increasing from 15.5% (Very Low) before the intervention to 61.14% (Average) after the intervention. The t-value obtained was -22.19, indicating a substantial difference in the scores before and after the intervention or treatment related to solving polynomials. This large negative t-value suggests a strong effect of the treatment on the students’ ability to solve polynomials. This significant improvement in scores indicates a highly positive impact of the Mathema Tic-Tac-Toe intervention on students’ ability to solve polynomial problems. The results suggest that the intervention is effective in enhancing students’ performance in this area, demonstrating a strong and beneficial effect on their Mathematical skills. The teacher may use this intervention in their mathematics classes to improve the problem solving skills of the students in polynomials.
