The information obtained in the process of learning mathematics in class IV has not been implemented optimally and refers to the objectives set out in the curriculum. As well as from the results of interviews at SD Negeri 01 Bancarkembar Purwokerto Utara has been known that the number of students with a low average score is the subject of mathematics. Students still find difficulties in the process of calculating quickly, in this case fast count method used is the method of finger. Therefore must be a media learning such as visualization of android-based finger method as an alternative medium to help students in fast counting. The purpose of this research is to design and build the visualization of android-based fingerprint method as an alternative media of students in learning to calculate quickly using the method of finger. Methods of data collection using interviews, literature and literature study. The method used for system development in this research is Multimedia Development Life Cycle (MDLC) Luther Sutopo version. The results of this research is a visualization of anroid-based fingerprint method is the application as a medium of learning mathematics material fast count operation multiplication using the method of jarimatika for class IV. The conclusion of this research that has succeeded in making visualization of anroid-based fingerprint method is the application as a medium of learning mathematics material of fast count operation multiplication using method of finger for class IV.
