"Localized Game-Based Learning Activities" is a supplementary learning resource designed to enhance the mathematical skills of Grade 7 learners. These activities incorporate cultural concepts, including games, beliefs, practices, as well as the tangible and intangible cultural heritage of the Ilocanos. Trivia based on these cultural elements serves as a catalyst for developing learners' competencies. These LGBLAs provide students with the freedom to learn at their own pace while utilizing community resources to master the subject matter. By incorporating game-based elements and integrating Ilocano cultural elements into the exercises, along with concise presentations of mathematical principles and illustrative examples, we aim to offer sufficient challenges to foster learners' progression and cultivate positive mathematical ideas and attitudes. The lessons and activities are aligned with the Most Essential Learning Competencies (MELCs) for Grade 7 Mathematics as mandated by the Department of Education. They are carefully organized to establish connections between significant concepts, allowing students to develop a deeper understanding of Mathematics.
