This study aims to determine the increase of student learning activeness through the demonstration method of concrete objects in the line and angle material in Junior High School. This type of research was Class Action Research conducted collaboratively between teacher and researcher at MTsN Batang Toru. The research subjects were 40 students of class VII-4. Data collection techniques were carried out by observation and distribution of questionnaires. The data analysis technique used is the analysis of the Miles and Huberman models with three stages, namely data reduction, data display, and drawing conclusions. This research through three cycles to obtain the desired results. The results of this study indicate that student learning activeness increases significantly. The results of the observation during the learning process showed the observations of the first cycle, the first meeting, the activity of students was 34.82%, and the second meeting was 42.33%. The 1st cycle of the 1st meeting was 51.5%, the second meeting was 63.83%. The third cycle of the 1st meeting was 74.16%, at the second meeting increased by 85.16%. Moreover, measuring the level of student activity was carried out by distributing questionnaires at the end of each cycle. The results of the questionnaire showed that respectively in the first cycle reached 44.16%, the second cycle 64.16, and the third cycle 84.33%. It can be concluded that the activeness of students in line material and angles in mathematics lessons using the concrete object demonstration method increases as expected.
