This study discussed on the effectiveness of the use of mathematical learning tools based on guided inquiry models to improve mathematical communication skills (CS) for students of grade VIII SMP. The type of development research used is the Plomp model. The study was conducted on 30 students in one class to use learning tools, then given a final test to see how many students completed the test. The results showed that 86.6% had completely exceeded the minimum completeness criteria that had been set at 70. It could be concluded that the learning tools developed in the form of RPP and SW were effective in improving students' mathematical communication abilities so that they were suitable for use.
