This study aims to describe: 1) the validity, practicality and effectiveness of the teaching materials developed, 2) describe the improvement of students' mathematical reasoning abilities using the developed teaching material. The development of teaching materials based on the metacognition approach uses a 4-D model developed by Thiagarajan, Semmel and Semmel. The subjects in this study were students of class VIII-8 and VIII-9 SMP Negeri 17 Medan. From the results of field trials I and field trials II obtained: 1) teaching materials that meet valid, practical and effective criteria, 2) there is an increase in mathematical reasoning abilities.
