Innovating Math Instruction: Using the Japanese Multiplication Method (Jamm) in Teaching One-Digit Multiplication to Grade 4 Learners

Mastering multiplication was a crucial mathematical skill needed by elementary learners, yet many Grade 4-Earth learners struggled with memorization and recall, prompting the need for alternative methods such as the Japanese Multiplication Method to enhance their learning experience. This participatory action research aimed to address the challenges faced by Grade 4 learners in mastering multiplication due to poor memory and recall. The purposely selected participants included eight learners—three boys and five girls—who were identified through interviews with their adviser and a review of archival records. Data were gathered using observation guide, researcher’s journals, and interviews. The findings showed that the Japanese Multiplication Method was highly favored by the learners as an alternative approach to traditional multiplication strategies because it was easier, more efficient, faster, and more enjoyable. The results suggested that this intervention significantly enhanced learners' one-digit multiplication skills, providing a more effective and engaging method for improving their mathematical competencies. The implications of this study highlighted the potential for using this method to boost learners' ability to perform one-digit multiplication, thus contributing to better academic outcomes in Mathematics.
