The basis of the issue in this study is that students' KPMM is not optimal. Therefore, the goal of this study is to create contextual-based mathematics teaching materials on the topic of SPLDV to facilitate KPMM of phase D learners that meet the validity and practicality requirements. The study method utilised the ADDIE model, which includes analysis, design, development, implementation, and evaluation. The research subjects involved were students of SMPN 8 Pekanbaru with details of 6 people from class VIII.9 in the small group test, and 25 people from class VIII.2 in the large group test. Data collection instruments used validation sheets and learner response questionnaires. The results of the study obtained a material expert validity value of 87.2% and a media expert validity of 87.2%, both of which were classified as “very valid”. Meanwhile, the practicality value of the small group test was 93.1% and in the large group test 90.3%, both of which were classified as “very practical”. So, it is concluded that the products in this study are valid and practical.
