Learning Mathematics requires students to have mathematical communication skills. This study aims to analyze the communication skills of students on the curved side solid figure material. The type of the research is descriptive qualitative research. The subjects of this study were 6 highly skilled students, medium and low ability students selected from 24 students of SMP Negeri 33 Pekanbaru in 2019/2020.
