Abstract

Learning number concepts in lower grades (grades 1-3) serves as the primary foundation in elementary school mathematics education. This study aims to analyze the challenges, strategies, and role of learning media in helping students in grades 1-3 develop a deep understanding of number concepts. A descriptive literature review approach was employed by analyzing relevant research from 2016 to 2026. The findings indicate that lower grade students frequently face difficulties in understanding place value, number symbols, and basic arithmetic operations. Contributing factors include limited learning media, teacher-centered methods, and insufficient opportunities for concrete hands-on experiences. The use of manipulative media such as number bags, number cubes, and natural materials has been shown to significantly improve students' conceptual understanding and learning motivation. Contextual approaches that connect number concepts to students' real-life experiences also positively impact engagement and academic outcomes. This article recommends enhancing teachers' competency in selecting and developing innovative learning media and promoting school-level policies that support the provision of adequate learning resources.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model Discovery Learning terhadap kemampuan pemecahan masalah pada materi Kelipatan Persekutuan Terkecil (KPK) dan Faktor Persekutuan Terbesar (FPB) siswa SD Negeri 008 Langgini. Penelitian ini menggunakan pendekatan kuantitatif dengan desain one group pretest–posttest. Sampel penelitian berjumlah 15 siswa kelas IV yang dipilih menggunakan teknik total sampling. Instrumen penelitian berupa tes kemampuan pemecahan masalah KPK dan FPB yang diberikan sebelum dan sesudah penerapan model Discovery Learning. Data dianalisis menggunakan bantuan program SPSS versi 26, meliputi uji normalitas dan uji paired sample t-test. Hasil uji normalitas menunjukkan bahwa data pretest dan posttest berdistribusi normal dengan nilai signifikansi masing-masing sebesar 0,200 > 0,05. Hasil uji paired sample t-test menunjukkan adanya perbedaan yang signifikan antara nilai pretest dan posttest dengan nilai Sig. (2-tailed) sebesar 0,000 < 0,05. Rata-rata nilai pretest sebesar 56,67, sedangkan rata-rata nilai posttest meningkat menjadi 82,00. Dengan demikian, dapat disimpulkan bahwa model Discovery Learning berpengaruh signifikan terhadap peningkatan kemampuan pemecahan masalah KPK dan FPB siswa SD Negeri 008 Langgini.
