Innovative approaches are required to address the issues children face in their early education stages, particularly concerning literacy and numeracy skills, which emerge before their entry into formal schooling. The research resulted in developing a conventional three-dimensional book-based learning medium named KriyaVidya, which comprises motor and sensory activities designed to stimulate children's interest in literacy and numeracy, particularly during preschool. This research uses the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) as a five-stage development framework. In this study, data analysis was carried out using both quantitative and qualitative approaches. Quantitative data consisted of expert judgments assessing the book's suitability. Meanwhile, qualitative data consisted of feedback and suggestions from the validators and responses from parents. The content validity analysis, assessed using v Aiken, ranged from 0.75 to 0.875, considered valid for early childhood. Some revisions were made to the book design to improve durability, safety, and suitability for adolescents. The results suggest that KriyaVidya books can be used to promote literacy and numeracy in early childhood. © 2025 Author(s).
