    Most students do not understand the concept of subtraction. These problems appear because the learning of mathematics is not meaningful for students. Based on this phenomenon, researcher is interested in designing a method of learning subtraction by using GASING method. The purpose of this research is to describe the role of a GASING method to improve students' understanding of two-digit subtraction from a concrete sample into an abstract symbol. As a result, the students are able to calculate mentally (calculate in their head, without scratching on paper) and do worksheets. The method is integrated with design research which consists of preliminary design stages, teaching experiment, and retrospective analysis. This research describes how the learning of subtraction with GASING method improves the understanding of 2nd grade students of SDN Cihuni II Tangerang. The results showed that the method could stimulate students to understand the concept of subtraction. Secondly, GASING method can enhance students' understanding of doing subtraction where the students are able to count more quickly and easily. The researcher should be able to transfer the design of learning to the teacher as the object of the research. Therefore the results of the research can be successful. In addition, the learning of subtraction by using GASING methods can be developed for multi digit number and another number operation. Keywords: design research, GASING Method, subtraction
