The effectiveness of games as a tool for teaching concepts while motivating and inspiring students is now well accepted in almost all subjects and levels of education. This study addressed the development and validation of pinoy gamebased activities. The research utilized the R&D methodology which included the validation of the activities and try-out where in the quasi-experiment following a one-shot-prestest-postest design was used. It was found out that the pinoy game-based activities were valid in terms of their instructional characteristics, objectives, content and evaluation categories and therefore, are good materials in concretizing learning of some physics concepts. Moreover, there was a significant difference between the pre and post achievement scores of the students and a positive feedback towards physics were also drawn from them. The pinoy-game based activities affirmed their worth and advantage as instructional material in teaching concepts of work, power and energy and enhancing students’ achievement and interest towards the subject.
