This study took the subjects from private junior high schools in Cimahi as many as 25 grade IX students. The data collection technique is by means of test questions, consisting of 5 questions in description with each question representing one indicator of mathematical communication. Based on the data analysis, it was found that the mathematical communication skills of grade IX junior high school students on the curved side of the building material were quite good. Of the 5 indicators of mathematical communication, there are 2 indicators that are classified as high, namely the indicator that states the situation becomes a mathematical model and the indicator interprets the mathematical model into ordinary language.
