This study aims to integrate the local wisdom of the traditional engklek game into problem-solving-based mathematics learning at the elementary school level. The method used in this study is a mixed-method with an explanatory design. The data analysis technique used in this study was random sampling and data collection was carried out by distributing observation sheets about student process skills, student learning interest questionnaires and conducting interviews with students and teachers at the school. Based on the results obtained by the researchers, it can be found that there is interest in learning and skills of students in grades IV A and IV B in the engklek game in mathematics subjects at State Elementary Schools. In addition, there is a relationship between students' interest in learning and students' process skills in mathematics subjects at State Elementary Schools. Key words: Mmathematics, local Wisdom, engklek games, iinterest, process skills, elementary School.
