Background: The topic of curved-surface solid volume in elementary school is often associated with students’ low conceptual understanding. Objectives: This study aims to describe the concept of curved-surface solid volume and to explain the implementation of a contextual learning approach in improving elementary students' understanding of the topic. Method: This study employed a descriptive qualitative approach using a literature review and conceptual analysis method. The background of this study is the limited comprehension of students regarding the concepts of cylinder, cone, and sphere volumes, as instruction tends to be teacher-centered and abstract. Data were obtained through the examination of textbooks, scientific journal articles, and relevant instructional documents.Result: The findings indicate that the implementation of a contextual learning approach through the use of real objects such as beverage cans (cylinders), ice cream cones (cones), and soccer balls (spheres) helps students understand volume concepts more meaningfully. Implication: The learning process, which connects mathematical material to students’ daily experiences, increases engagement, conceptual understanding, and problem-solving skills.Conclusion: Therefore, contextual learning can serve as an effective alternative in improving the quality of mathematics instruction, particularly in teaching the volume of curved-surface solids in elementary schools.
