Tujuan penelitian ini adalah untuk mengetahui keefektifan model think pair share berbantu media ular tangga terhadap kemampuan pemecahan masalah matematika siswa kelas V SD Negeri Bogangin 01 Banyumas. Penelitian ini adalah penelitian kuantitatif menggunakan desain penelitian True Experimental Design dengan jenis penelitian Posttest Only Control Design. Hasil uji ketuntasan belajar menunjukan bahwa kemampuan pemecahan masalah siswa yang menggunakan model think pair share berbantu media ular tangga mencapai presentase klasikal sebesar 91,6%. Nilai rata-rata kelas eksperimen 81,58 dan  kriteria ketuntasan minimum (KKM) 72, diperoleh t_hitung 5,38 dengan n = 24, dan t_tabel 2,06. Sehingga hasil perhitungan diketahui 5,38 > 2,06. Berdasarkan hasil uji banding dua sampel, diperoleh t_hitung > t_tabel yaitu 2,55 > 2,02 sehingga H0 ditolak dan Ha diterima. Kesimpulannya model think pair share berbantu media ular tangga efektif terhadap kemampuan pemecahan masalah matematika siswa kelas V SD Negeri Bogangin 01 Banyumas.

Abstract: The purpose of this research is to know the effectiveness of think pair share model assisted by snake ladder media to solving problem of math class V student of SD Negeri Bogangin 01 Banyumas. This research is a quantitative research using True Experimental Design research design with research type Posttest Only Control Design. The result of learning completeness test shows that the problem solving ability of students who use think pair share model of snake ladder media reaches a classical percentage of 91,6%. The average value of the experimental class 81.58 and the minimum completeness criterion (KKM) 72, obtained tcal 5.38 with n = 24, and ttabel 2.06. So the calculation result is known 5.38> 2.06. Based on the result of the comparison test of two samples, obtained tcount> ttable that is 2.55> 2.02 so that H0 is rejected and Ha accepted. In conclusion the model of think pair share aided snake ladder effectively against the ability of solving problems of math class V students of SD Negeri Bogangin 01 Banyumas.
