摘要：Several studies on learning mathematics f or rural area 's student indicate that students have difficulty in understanding t he concept of divisi on operation . Students are more likely to be introduced by the use of the formula without involving the concept itself and learning division separate the concrete situation of learning process . This underlies the researcher to design division operation learning in the Mathematics of GASING (Math GASING) , which always starts from concrete to abstract level . The research method used is a design research which describes how the Math GASING make a real contribution of students understandin g in the concept of division operation.
