This study aims to examine the effect of the Snowball Throwing cooperative learning model on the mathematics learning outcomes of fifth-grade students at SDIT Ghilmani Surabaya, focusing on the topics of Least Common Multiple (LCM) and Greatest Common Factor (GCF). This research employed a quantitative approach with a one-group pretest–posttest design. The participants consisted of 24 fifth-grade students. Data were collected through learning achievement tests administered before and after the implementation of the Snowball Throwing model. The data were analyzed using a paired sample t-test to determine the significant difference between pretest and posttest results. The findings revealed a significant improvement in students’ learning outcomes, as indicated by an increase in the average score from 53.5 to 83.2 after the treatment. Moreover, 87.5% of students achieved the minimum mastery criterion after the implementation, compared to only 16.7% before. Classroom observations showed that students became more active, enthusiastic, and confident in expressing their ideas, while teachers acted as facilitators. The Snowball Throwing model also fostered a fun learning atmosphere, enhanced students’ critical thinking, collaboration, and sense of responsibility. Therefore, it can be concluded that the Snowball Throwing cooperative learning model has a positive and significant effect on improving mathematics learning outcomes in elementary schools and serves as an effective alternative to create an active, interactive, and meaningful learning environment.

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe Snowball Throwing terhadap hasil belajar matematika siswa kelas V SDIT Ghilmani Surabaya pada materi Kelipatan Persekutuan Terkecil (KPK) dan Faktor Persekutuan Terbesar (FPB). Penelitian ini menggunakan metode kuantitatif dengan desain one group pretest-posttest. Subjek penelitian berjumlah 24 siswa kelas V. Data diperoleh melalui tes hasil belajar yang diberikan sebelum dan sesudah penerapan model Snowball Throwing. Analisis data menggunakan uji-t sampel berpasangan (paired sample t-test) untuk mengukur perbedaan signifikan antara hasil pretest dan posttest. Hasil penelitian menunjukkan adanya peningkatan yang signifikan pada hasil belajar siswa, ditunjukkan dengan peningkatan rata-rata nilai dari 53,5 menjadi 83,2 setelah penerapan model pembelajaran. Sebanyak 87,5% siswa mencapai KKM setelah perlakuan, dibandingkan hanya 16,7% sebelum perlakuan. Selama kegiatan di kelas, siswa terlihat lebih aktif, antusias, dan berani mengemukakan pendapat, sementara guru berperan sebagai fasilitator. Penerapan model Snowball Throwing juga menciptakan suasana belajar yang menyenangkan, meningkatkan kemampuan berpikir kritis, kerja sama, dan tanggung jawab siswa. Dengan demikian, dapat disimpulkan bahwa model pembelajaran kooperatif tipe Snowball Throwing berpengaruh positif dan signifikan terhadap peningkatan hasil belajar matematika siswa sekolah dasar, serta dapat menjadi alternatif pembelajaran yang efektif untuk menciptakan suasana kelas yang aktif, interaktif, dan bermakna.
