<![CDATA[Mathematics learning requires instructional materials that can support students in understanding abstract concepts and solving problems systematically. However, students often experience difficulties in translating contextual problems into mathematical models and applying appropriate procedures to solve systems of linear equations in two variables (SLETV). This study aimed to develop a scaffolding-based Student Worksheet (LKPD) that is valid, practical, and effective in supporting students’ mathematics learning. The study employed a Design Thinking approach consisting of five stages: empathize, define, ideate, prototype, and test. The development process involved a mathematics teacher and ten students. Product quality was evaluated through expert validation, teacher and student response questionnaires, and student learning outcomes. The results showed that the worksheet achieved an average validity score of 97.72%, indicating a very high level of validity. The practicality assessment reached an average of 91.81%, demonstrating that the worksheet was highly practical for classroom use. Furthermore, 80% of the students achieved the established learning mastery criterion, indicating that the worksheet met the effectiveness criterion. These findings suggest that scaffolding-based worksheets can provide structured learning support and help students approach mathematical problems step by step. The developed LKPD offers teachers an alternative instructional resource for facilitating SLETV learning and may serve as a reference for developing similar materials for other mathematical topics.]]>
