The integration of digital technology in mathematics learning requires instructional media that can assist students in understanding abstract concepts, particularly in three-dimensional geometry. This study aimed to analyze the utilization of digital coding-based learning media in mathematics learning on three-dimensional geometry for third-grade students at SDN Klampok 02. This research employed a descriptive qualitative approach involving a third-grade teacher and third-grade students as research participants. Data were collected through observation, interviews, and documentation, and analyzed using Sugiyono's qualitative data analysis procedures, consisting of data collection, data reduction, data display, and conclusion drawing. The findings indicate that the teacher utilized the GYNZY platform displayed through a Smart TV to present three-dimensional geometry materials in a visual and interactive manner. The use of this digital coding-based learning media supported the implementation of learning by presenting more concrete learning materials, encouraging teacher–student interaction, and increasing student engagement during classroom activities. Learning evaluation was conducted through oral questioning, student worksheets (LKPD), and observation of students' learning activities, followed by re-explanation, additional practice, and individual guidance for students who still experienced learning difficulties. In conclusion, digital coding-based learning media support the implementation and evaluation of mathematics learning on three-dimensional geometry in Grade III at SDN Klampok 02.
