The purpose of this study is to find out how to develop learning tools using the Problem Based Instruction model with a realistic mathematical approach on the subject of statistics and to produce learning tools using the Problem Based Instruction model with a realistic mathematical approach to the subject of valid, practical, and effective statistics. The sample in this study was taken from students of class VII A, SMP Negeri 10 Manado. The number of students studied was 38 students. In this research the RPP, LKS, and THB models of Problem Based Instruction are developed with a realistic mathematical approach on the subject of statistics. The development model used in this study is a modification of the 4D model. The results of this study stated that the products developed met valid, practical, and effective criteria. Learning devices with an average score of 3.57 with valid criteria. The practicality results of learning tools are obtained from the ability of teachers to manage learning categorized as good which is located in intervals of 3≤P<4 and student questionnaire responses that are above 80% of students' positive responses. The effectiveness of learning tools obtained from evaluating student learning outcomes that indicate the value of student learning completeness above 70.
