This study aims to discuss the practicality of RME-based mathematics learning devices to improve the mathematical communication skills of Vocational Grade X students in construction and property engineering skills programs. Research focuses on the small group phase. This phase, the researcher applied a mathematics learning tool that involved 6 students, namely 2 high-ability students, 2 moderate-capable students, and 2 low-ability students, and a mathematics teacher acting as an observer. Data collection in this study was obtained from the results of the observation sheet, teacher and student response questionnaire. The results of the observation sheet and teacher response questionnaire showed that RME-based mathematics learning tools were practical with values of 84.85% and 82.67% respectively. the results of the student response questionnaire showed that the RME- based Students worksheet (LKPD) was very practical with a value of 87.23%. © 2019 IJSTR.
