The purpose of the study is to know students’ mathematical communication skills in finding the direct and inverse proportions through discovery learning. The data is obtained based on the work of students in solving the problems that measure students’ mathematical communication skills. The data is categorized on 5 levels (the lowest level is 0 and the highest level is IV) which refer to the quantitative criteria for scoring mathematical communication and analyzed descriptively. From the leveling result, it is obtained that students on level II are 31.25% and level III are 68.75% in mathematical communication skills. The results reveal that the Discovery Learning can foster the mathematical communication skills of junior high school students especially in concepts of the direct and inverse proportions.
