Pengembangan ini bertujuan untuk menghasilkan produk yang layak dari segi kevalidan, kemenarikan, keefektifan, serta keterterapan dalam pembelajaran. Penelitian dan pengembangan ini dikembangkan berdasarkan langkah-langkah pengembangan model Borg and Gall yang diadaptasi oleh Sugiyono. Langkah-langkah tersebut meliputi identifikasi masalah, pengumpulan informasi, desain produk, validasi desain, perbaikan desain, uji coba produk, revisi produk, uji coba pemakaian, revisi produk tahap akhir, dan produksi massal. Hasil validasi diperoleh dari tiga ahli. Rata-rata persentase validasi gabungan dari tiga ahli adalah 85,6% termasuk kriteria sangat valid. Hasil persentase keterterapan diperoleh dari lembar observasi aktivitas guru dan siswa. Rata-rata persentase keterterapan gabungan dari lembar observasi aktivitas guru dan siswa adalah 87,3% termasuk kriteria sangat dapat diterapkan. Persentase keefektifan produk dari hasil belajar siswa adalah 95,6% termasuk kriteria tuntas dan efektif. Persentase kemenarikan produk adalah 86,9% termasuk kriteria sangat menarik. Hasil tersebut menunjukkan bahwa media kota stick matematika sangat valid, sangat dapat diterapkan, tuntas dan efektif, serta sangat menarik.
