The implementation of the MATATAG curriculum has introduced a new time allocation of forty- five (45) minutes per subject. This study aimed to determine the opportunities and challenges faced by teachers in adapting to the shortened class periods. A descriptive phenomenological design was used to describe the lived experiences of teachers. Purposive sampling was employed to conduct in-depth interviews with eight (8) teachers. The data gathered was analyzed using Colaizzi’s thematic analysis method, resulting in five (5) key themes, referred to as the “5T’s”: (1) Time Constraints and Management, (2) Teaching Strategies to Foster Student Engagement, (3) Teaching Challenges and Barriers to Effective Instruction, (4) Teacher Wellness, and (5) Trials Encountered by Students in their Learning Environment. The results showed that teachers face difficulties in delivering lessons within the limited time frame, but they adjust their teaching strategies to improve student engagement. To address these concerns, it is recommended that the class period be extended to allow for more in-depth interaction, offer professional development on time and stress management, and initiatives that promote teacher wellness. The study provides recommendations for policymakers, educators, and future research on enhancing the effectiveness of the MATATAG curriculum and supporting teachers in their roles.
