This study aims to produce Student Worksheets based on PMRI's approach used the context of unloading houses with categories valid and practical as well as to determine the potential effect on ability students' mathematical connections. This research was a Research and Development with the development research model used the ADDIE development (Analysis, Design, Development, Implementation, and evaluation). Validity data was obtained based on the validity of the questionnaire data analyzed descriptively by analyzing comments and suggestions from the validator. Data practicality obtained based on the questionnaire data used to determine the practicality of the LKPD was analyzed using a Likert scale with a score rule of student response questionnaire. The potential effect of the results of the analysis of student answers on the test evaluation in LKPD. The subjects of this study were eighth grade students of SMP Az-Zawiyah Tanjung Batu. The results of this study indicated that the LKPD that developed declared valid based on the comments and suggestions of the validator and practical based on student response questionnaires and the developed LKPD has potential effect on students' mathematical connection ability. Keywords: LKPD, PMRI approach, students' mathematical connection ability.
