abstract={An adequate and appropriate utilization of instructional materials has always been an essential component in the learning process that influences learning outcomes. Despite the recognized potential of instructional materials and the encouragement of authorities among teachers to contextualize their own, there remains a lack of synthesized evidence on the effective design and implementation of mathematics instructional materials across various grade levels. This systematic review aimed to consolidate research on instructional materials in mathematics, particularly on their development and validation. The review included five (5) literature reviews that followed a designed inclusion criterion. Findings reveal that contextually relevant and rigorously validated materials significantly enhance learner engagement and comprehension. However, limited validation scope and incomplete topic coverage remain a challenge, particularly for higher-level mathematical concepts. Supplementary and inquiry-based materials show positive effects on student learning, though most studies lack long-term impact assessments. Teacher and student feedback highlight practical usability issues, underscoring the need for participatory validation and professional development. Additionally, embedding active learning strategies and ensuring regional and cultural relevance improve effectiveness but require better dissemination and scaling. Overall, developing instructional materials demands a comprehensive, iterative approach that balances content accuracy, pedagogical soundness, and contextual adaptation to support diverse learners effectively.},
