The objective of this research is to improve learning outcome of mathematics about plane through the use of guided inquiry model using concrete media for the fifth b grade students of SD Negeri 1 Sidoharum. This research is a collaborative Classroom Action Research (CAR). Each cycle consisted of planning, action, observation, and reflection. Subjects of the research were teacher and 20 students of the fifth B grade of SD Negeri 1 Sidoharum. Sources of data were derived from students, teacher, and observer. Techniques of collecting data were learning outcomes test, observation, interview, and documentation. Validity of data in this research was analyzed using triangulation of sources and triangulation of technique. Data were analyzed using quantitative and qualitative descriptiveanalysis consisting of data reduction, data display, and drawing conclusion or verification. This research was discontinued when the results and process of students had reached KKM = 75 about 80% students and the indicators had been completed. The results of this research show that the use of guided inquiry model using concrete media can improve learning outcome of mathematics about plane for the fifth b grade students of SD Negeri 1 Sidoharum in the academic year of 2016/2017.Keywords: guided inquiry, concrete media, learning outcome, mathematics, plane.]]>
