Abstract: This research was conducted at Satap Molingongot State Junior High School. This study aims to produce development products for geometry learning tools in the form of Lesson Plans, Worksheets, and Learning Outcomes Test Instrument that meet valid, practical and effective criteria using the modified 4 - D Thiagarajan development model. The results of the study show that learning tools meet valid criteria, which is seen from the results of validation from experts with an average value given of 4.16 for lesson plans, 4.07 for worksheets and 3.89 for THB. The results of the practicality test show that the learning device meets the practical criteria, which can be seen from the results of the observation sheet the teacher's ability to manage learning is in the very good category and the results of the student response questionnaire analysis are on average 4.72 which concludes that the student response is positive. While the results of testing the effectiveness of learning devices meet the effective criteria, namely the percentage of classical completeness of student learning outcomes tests is 80%.
