This research is motivated by the majority of students who still have difficulty in describing various flat shapes and arranging them into a single unit during the learning process. The purpose of this study is to describe the implementation of E- Tangram media on composition and decomposition materials. The research method used is quantitative descriptive with a test instrument used to measure students' understanding after using E-Tangram media. The results showed that the average pretest score of students was 62, increasing to 90.5 in the posttest after using E-Tangram media. This increase was analyzed using the N-gain formula and obtained a score percentage of 0.75 with a high category. The conclusion of this study is that E-Tangram media is very effective in improving students' understanding of composition and decomposition materials. In addition, the use of E-Tangram media in learning shows more active and enthusiastic involvement in mathematics learning.
