This research development aims to determine the results of LKPD development using CTL in facilitating mathematical representation ability students. Subjects in this research development is all students of class VIII.10 with the number of students 35 people in SMP Negeri 1 Gadingrejo academic year 2016/2017. The stages of development were research and information collecting, students worksheet prepartion, students worksheet validation, preliminary field testing and main field testing. The data of this research were obtained by observation, interview, questioneirs, and mathematical representation ability test. The material and media expert said that of the students worksheet development was valid. Based on data analysis of test results and observations during the study. Overall the product developed is effective enough to be used, it is shown by the average of N-gain ability of mathematical representation equal with enough effective criterion. The conclusion of this research is LKPD using CTL in mathematics learning has been able to facilitate students mathematical representation ability.Penelitian pengembangan ini bertujuan untuk mengetahui hasil pengembangan LKPD dengan menggunakan pendekatan CTL dalam memfasilitasi kemampuan representasi matematis siswa. Subjek dalam penelitian pengembangan ini adalah seluruh siswa kelas VIII.10 dengan jumlah siswa 35 orang di SMP Negeri 1 Gadingrejo tahun ajaran 2016/2017.
