Supporting the 21st-century learners' instructional needs is a trend of today's educational system. This educational design research aimed to develop a Digital Interactive Math Comics (DIMaC) as an instructional material envisioned to meet these learners' needs to a better understanding of Mathematics concepts. This employed the ADDIE framework for instructional material development design. There were 425 randomly chosen students who took the validated and acceptable with 0.7888 Cronbach's alpha researcher-made General Mathematics Competency Test. This was done to identify the least learned skills and be the basis for design and development. The initial storyline with the Mathematics contents integrated were validated by the set of experts before the electronic illustrations and coding took place. The initial outputs of the DIMaC were revalidated for comments and suggestions before distribution for classroom use. These experts also evaluated the final version of DIMaC as very acceptable. The DIMaC was then implemented in a classroom and found to have high usability as rated by the students. Also, the app draws positive feedback for classroom use because of its interesting nature and uniqueness. Thus, this study adds to the body of literature on helpful instructional materials for utilization to these tech-savvy learners.
