This study determined the effect of utilizing math creative games as intervention material in teaching basic mathematics of the blended students of Banca-Banca Integrated National High School S.Y. 2021-2022. The information on related literature and studies were gathered to formulate the objectives of the studies. Specifically, the information is found in books, journals, documents, published and unpublished materials like thesis, journals, and the internet. It specifically sought to determine the level of math creative games in terms of characteristics with regards to usability, appropriateness, and usefulness; the level of math creative games in terms student engagement with regards to attention, curiosity and interest; the level of students performance in basic mathematics in terms of pre-test and post-test; significant difference in the performance of the students in utilizing math creative games as intervention material in teaching basic mathematics in pre-test and post-test; and to determine the significant effect to the performance in utilizing math creative games as intervention material in teaching basic mathematics. Findings revealed the following: (1) The level of characteristics of math creative games with regards to usability, appropriateness, and usefulness were very evident as evaluated by the respondents of the study. (2) The level of student engagement in using math creative games in terms of attention, curiosity and interest were very evident as evaluated by the respondents of the study. (3) The level of students? performance in using intervention material in teaching Basic mathematics in terms of pre-test and post-test of the respondents resulted that from Approaching Proficient to Proficient after they use the Math Creative Games as intervention materials. (4) The test of the difference between the pre-test and post-test of the respondents resulted that there is a significant difference in the performance of the students in utilizing math creative games as intervention material in teaching basic Mathematics in pre-test and post-test. This implies that there is a significant improvement in students' basic mathematical abilities. (5) The test of significant effect to the performance in utilizing math creative games as intervention material in teaching basic Mathematics was not observed to have any significant effect to the performance of the students based on the characteristics of the games and the indicators under the students? engagement. The research hypothesis ?There is no significant difference in the performance of the students in utilizing math creative games as intervention material in teaching basic mathematics in pre-test and post-test? was rejected. While research hypothesis ?There is no significant effect on utilizing math creative games as intervention material in teaching basic mathematics to the blended students.? was accepted.
