The purpose of this study is to produce mathematical learning tools model of problem based learning to teach material number patterns, which meet the criteria of valid, practical, and effective. This research method is categorized as development research. The sample in this study was taken by eighth grade students of SMP Negeri 3 Tondano. In this research the RPP, LKPD, and EHB developed using the problem based learning model on material number patterns. The results of this study stated that the products developed met valid, practical, and effective criteria. Learning devices are feasible to use based on the evaluation of learning tools by the validator with an average score of 3.9 with valid criteria. The practicality results of the learning tools were obtained from the student response questionnaire which showed a score of 23 included in the practical criteria. The effectiveness of the learning device is obtained from the evaluation of student learning outcomes which shows the completeness of student learning above 70 so that it can be concluded that the learning device is effectively used in learning.
