Salah satu media yang dapat dimanfaatkan dalam menyampaikan materi program linear adalah software GeoGebra. Penelitian ini bertujuan untuk mendeskripsikan hasil uji coba LKS berbantuan software GeoGebra pada materi Program Linier. LKS diujicobakan secara terbatas kepada 6 siswa kelas XI SMA Wachid Hasyim 2 Taman dan selanjutnya akan dianalisis secara kualitatif berdasarkan hasil kerja siswa, catatan yang diperoleh dari pengamatan langsung selama proses uji coba, dan hasil wawancara mengenai respon guru dan siswa terhadap LKS yang digunakan serta pemahaman siswa pada materi Program Linier setelah mengerjakan LKS berbantuan software GeoGebra. Berdasarkan hasil uji coba terbatas diketahui bahwa LKS efektif digunakan dalam pembelajaran matematika pada materi Program Linier. Respon siswa terhadap LKS tersebut baik, berdasarkan hasil wawancara diketahui baik siswa maupun guru merasa terbantu dengan adanya LKS berbantuan Software GeoGebra ini serta dapat meningkatkan motivasi belajar siswa.
