The low scores of the National Achievement Test and the Trends in Mathematics and Science Study in 2019 proved a setback for the Philippines' mathematics education. Researchers developed a board game to aid fourth graders in improving problem-solving abilities involving the perimeter of quadrilaterals and triangles. The study utilized a developmental research design. Mathematics experts implemented a rating sheet the Department of Education provided to evaluate the game using three categories (Content, Other Findings and Additional Requirements for Manipulative) with passing scores of 30, 16, and 18. The means from scores specified by the four raters were 36.75, 14, and 22. While these results clarified there is insufficient points to meet one criterion, the project remains implementable with indicated adjustments. Furthermore, a gap exists in studying the interactive game’s effectiveness in teaching mathematics due to limited onsite sessions. The researchers suggest future studies address this gap. In conclusion, the Acadi board game is a potential instructional material for Grade 4 mathematics, enhancing problem-solving skills.
