<![CDATA[This research aims to analyze the effect of using time board media in increasing students' conceptual understanding of time material in class 1 of SD Negeri 104202 Bandar Setia. The background to this research stems from students' low understanding of the concept of time due to learning methods that are still abstract. The research method used is Classroom Action Research (PTK) with the Kemmis and McTaggart model which consists of two cycles. Each cycle includes planning, implementation, observation, and reflection. The research results show that the use of time board media can significantly increase students' understanding of the concept of time. In pre-action, only 24.1% of students achieved good understanding, whereas after implementing time board media in the second cycle, this percentage increased to 72.4%. This increase shows that the time board media is effective in helping students understand the concept of time concretely. Thus, the use of time board media is recommended as an innovative learning strategy in increasing understanding of mathematical concepts in early grade students.]]>
