This study was motivated by initial observations indicating a lack of numeracy skills among children in Group A KB Aisviyah Tunas Melati, Losari. The lecture-based teaching method by teachers affected it. Consequently, children become bored and pay insufficient attention to the teacher during learning activities. To address this issue, an appropriate game-based method was needed to engage children and enhance their focus during learning. The study aimed to develope numeracy skill through the number stick playing media for children in Group A KB Aisyiyah Tunas Melati, Losari, Ampelgading district. The research methodology was Classroom Action Research (CAR), with the research subjects being children in Group A KB Aisyiyah Tunas Melati, Losari, Ampelgading district.
