Mastery of concepts in mathematics is essential for the Filipino 21st century learners. The Philippines, having ranked second lowest in the results of the educational achievement test administered through the Program for International Student Assessment (PISA) in 2018, it is but necessary that research studies be conducted to find out how mathematics could be taught to enhance learners’ skills in mathematics. Thus, this study made use of an intervention called Mathdali Intervention Program (MIP) which makes use of videos and games presented by the teacher thru tablets in her interactive classroom discussions. The participants were two classes in grade four from the Baliuag University Basic Education Department. Using the quantitative research design, it was revealed that the students improved in their mathematics performance in all the four quarterly exams administered during the school year. Their attitudes toward mathematics improved, and they perceived the intervention program as very effective. Themes gathered from the interviews include (1) usefulness of mathematics in one’s daily life, (2) motivation in learning and teaching mathematics, (3) ease in understanding mathematics, (4) improvement in math performance, (5) teaching mathematics as a learning experience, (6) training as beneficial for math teachers, and (7) Mathdali Intervention Program to be continued in the classroom. The program has been strongly recommended by the teacher and the learners having been proven effective in their mathematics classes.
