Abstract: This study aims to produce development products for mathematics learning tools in the form of Learning Implementation Plans (RPP), Student Worksheets (LKPD) and Evaluation of Learning Outcomes (EHB) that meet valid, practical and effective criteria using the 4 - D development model according to Thiagarajan who modified into 3 - D namely Define, Design and Develop on Geometry Sequences and Series material for class XI SMA Negeri 1 Motoling. The results of this study indicate that the quality of the product produced based on the validity aspect meets the good criteria for lesson plans with an average total validator rating of 4.19 and LKPD, EHB meets good criteria with an average total validator rating of 4.06. The practicality aspect based on the results of observations of the teacher's ability to manage learning meets the good criteria, as well as student responses to the device and positive learning. Meanwhile, based on the learning outcomes test it was found that the learning tools developed had a very good level of effectiveness with a learning completeness percentage of 81.25%.
