Abstract

Education has a crucial role in developing quality human resources, using increase learning being a key factor. However, mathematics learning in lower elementary grades often faces challenges, such as low student achievement due to limited variation in teaching methods and lack of media suited to young learners' characteristics. This study aims to improve mathematics learning outcomes specifically on addition and subtraction of numbers 1–20 for first grade students at SD 1 Jati Wetan by using the Student Teams Achievment Division cooperative learning model assisted by kalipus. The research used a collaborative Classroom Action Research (CAR) method, carried out in two cycles following the Kemmis and McTaggart model, involving 11 students. Data collection methods included observation and achievement tests, analyzed both qualitatively and quantitatively. This research was conducted from February 12 to May 12, 2025, the results showed a significant increase in student achievement, with average scores rising from 66.4 (pre-cycle) to 75.45 (Cycle I) and 88.18 (Cycle II). Mastery learning improved from 54% to 92%. These findings indicated that the STAD model with Kalipus media can improve students' arithmetic abilities and supports interactive learning aligned with early childhood cognitive development, contributing to innovative and engaging mathematics instruction in early education.
