<![CDATA[Mathematics learning outcomes among elementary school students often face challenges due to low student engagement and the abstract nature of mathematical concepts. This study aims to determine the effect of the Game-Based Learning (GBL) model assisted by congklak media on the mathematics learning outcomes of fourth-grade students at SDN 74 Palembang. This quantitative study utilized a posttest-only control group experimental design. The study population comprised all fourth-grade students, with a sample of 60 students selected through a simple random sampling technique. Data were collected using a mathematics achievement test and analyzed using an independent sample t-test. The results revealed that the average score of students in the control class was 43.83, whereas the experimental class achieved 75.70. Hypothesis testing through the independent sample t-test yielded a Sig. (2-tailed) value of 0.000, which is smaller than the significance threshold of 0.05 (); therefore, was rejected and was accepted. In conclusion, the Game-Based Learning model assisted by congklak media has a significant effect on improving the mathematics learning outcomes of fourth-grade students at SDN 74 Palembang. ABSTRAK Hasil belajar matematika siswa di sekolah dasar sering kali menghadapi kendala akibat rendahnya motivasi dan anggapan bahwa konsep matematika bersifat abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Game Based Learning (GBL) berbantuan media congklak terhadap hasil belajar matematika siswa kelas IV SDN 74 Palembang. Metode penelitian yang digunakan adalah kuantitatif dengan desain eksperimen posttest-only control group design. Populasi penelitian mencakup seluruh siswa kelas IV, dengan sampel yang ditentukan menggunakan teknik simple random sampling sebanyak 60 siswa. Teknik pengumpulan data menggunakan instrumen tes hasil belajar matematika, sedangkan analisis data dilakukan melalui uji prasyarat dan uji hipotesis menggunakan uji independent sample t-test. Hasil penelitian menunjukkan bahwa nilai rata-rata hasil belajar matematika siswa kelas kontrol sebesar 43,83, sedangkan kelas eksperimen mencapai 75,70. Hasil uji hipotesis menunjukkan nilai Sig. (2-tailed) sebesar 0,000, yang lebih kecil dari taraf signifikansi 0,05 (), sehingga ditolak dan diterima. Dengan demikian, terdapat pengaruh signifikan dari penerapan model Game Based Learning berbantuan media congklak terhadap hasil belajar matematika siswa kelas IV SDN 74 Palembang. ]]>
