AbstractThis study aims to improve the ability of subtraction calculation operation of first grade students of Madrasah Ibtidaiyah (MI) Tarbiyatul Athfal Gembong Pati using abacus media in learning. This research is a Classroom Action Research. The research subjects were first grade students of MI Tarbiyatul Athfal which amounted to 29 students by involving the principal as a collaborator and researchers as accompanying teachers and observers.
