Penelitian ini bertujuan untuk mengembagkan media pembelaiaran kartu domino yang layak digunakan dalam proses pembelajaran matematika materi satuan debit. Pengembangan ini dilakukan sesuai dengan tahapan dari Borg and Gall diadaptasi oleh Sugiyono dalam Emzir yaitu, identifikasi masalah, pengumpulan informasi, desain produk, validasi desain, perbaikan desain, uji cobapoduk, revisi produk, uji coba pemakaian,revisi pemakaian, produksi massal. Hasil pengembangan ini menunjukkan kelayakan media kartu domino diperoleh dari ahli media pembelajaran 86,6%, ahli desain pembelajaran 80%, dan ahli materi 80%.Keefektifan media kartu domino ditinjau dari obsenrasi aktivitas guru diperoleh persentase 92,5%, ditinjau dari lembar observasi aktivitas siswa diperoleh persentase 86,42%,dan hasil belajar diperoleh persentase 85%. Ketertarikan siswa pada media kartu domino memperoleh persentase 99,25%. Berdasarkan hasil pengembangan tersebut dapat disimpulkan bahwa media kartu domino yang dikembangkan layak digunakan dalam pembelajaran matematika satuan debit siswa kelas VI.
