The study aimed to determine the effectiveness of using the Math Stories in improving the performance of selected Grade 6 students from two (2) classes in Yukos Elementary School. Specifically, it sought to determine the level of math stories, the level mathematical performance of the students, and the significant difference between the mathematics performance of the students after the use of math stories. The research design used in this study was a quasi-experimental research design for determining the mathematics performance of the students using the pre-test and post-test and a descriptive research design in describing the level of Math stories using the criteria from a questionnaire. A purposive sampling technique was used to determine the respondents in the study. The statistical treatment of data was used to compute then analyze and interpret the data given by the respondents. After administering the questionnaire to the respondents, all the data were gathered, analyzed, and interpreted. Mean, standard deviation, frequency, and percentage were used to measure the pre-test and post-test of the students and to identify the level of the performance of the students in Math. Wilcoxon W was used as a statistical treatment to determine the significant difference in the pre-test and post-test scores of the students. Findings revealed that the pupils all strongly agreed that the language used in mathematics stories is appropriate to their level of understanding, and it helped them improve their comprehension skills. The level of the math performance of the students resulted in a great improvement from Beginning into Developing to Advanced. A significant difference was found between the pre-test and post-test math performance of the students. Based on the results and conclusion, the following recommendations were advanced: for students, apply mathematics stories when discussing and learning related topics to motivate, to improve the level of comprehension, and to facilitate understanding of complex mathematics concepts. For teachers, use mathematics stories which are relevant and fit to the level of understanding of the pupils to improve their performance in selected topics of Grade 6 mathematics. The future researcher may use this study as their reference guide.
