The current industrial revolution 4.0 requires us to simulate the important role of technology in all fields, especially the use of technology as a medium of learning. The technology chosen in this study using android technology developed into instructional-based math software with the help of construct 2 software on triangular material based on the TPACK framework. The purpose of this study is to face the era of industrial revolution that has developed very fast, which can be used as a learning tool for students, but it also aims to increase student motivation and interest. The learning media is an Android game developed with the help of software construct 2. This research type is a research development using 4D model that is Define, Design, Develop, and Disseminate. The study was conducted on 36 seventh grade students in junior high school. The results of this study showed the correlation coefficient of 0.92 with valid categories interpreted very high by using the validity test, the practicality test showed a percentage of 92% which means very good with the use of student response questionnaire, and the effective test showed a result of 96% that can be interpreted very effective in accordance with the analysis of student learning outcomes. The learning media using android games can be declared as valid, practical, and effective.
