<![CDATA[The purpose of this study was to determine whether the use of a wall clock as a learning aid improves the mathematics learning outcomes of third-grade students at Tanjung Jati 2 Elementary School on angles. This study used a classroom action research design and was conducted in two cycles, with 12 third-grade students at Tanjung Jati 2 Elementary School. The planning, implementation, observation, and reflection stages were the main stages. Data sources consisted of student learning outcomes and activities. Data were collected through tests, observations, and documentation, using test questions and observation sheets as tools. Student learning outcomes, as measured through pre cycle tests and each cycle, were analyzed using descriptive quantitative data. The results showed that students learned better. In the pre-cycle, the learning completion rate increased by 50%, in the first cycle, by 75%, and in the second cycle, by 100%. Furthermore, student engagement in learning and their activities increased. Therefore, the wall clock helped students understand concepts and improved learning outcomes. It is recommended that teachers use concrete and diverse learning media. Furthermore, broader material or subjects can be explored through additional research.]]>
