The research aims to produce mathematics learning tools in the form of lesson plans, worksheets, and THB on social arithmetic material using Cooperative Script learning models that have valid, practical, and effective qualifications. This research method is categorized as development research. In this research the RPP, LKS, and THB developed using the Problem based learning Model on the number pattern material. The results of this study state that the mathematics learning tool developed in this study is limited to the Learning Implementation Plan, Student Activity Sheets, and Learning Outcomes Tests on social arithmetic material for class VII SMP N 22 Halmahera Barat. The trial was only conducted in one class, which consisted of 39 students. Based on the research data, it can be concluded that a mathematics learning tool has been produced with ADDIE design model which includes five stages, namely: the analysis phase, the design phase, the development phase, the implementation phase, and evaluation phase modified evaluation results obtained: (1) Learning tools have been developed using Cooperative Script learning models on social arithmetic material for Grade VII students of SMP N 22 West Halmahera and meet valid, practical, and effective criteria, (2) Validity of devices based on learning models Cooperative Script is shown from the validation results of the validators against the device, (3) Practicality of the device based on Cooperative Script learning models is shown from the results of observations.
