Setelah diadakan pelatihan diperoleh bahwa calon guru CPNS 2019 memiliki kemampuan yang sangat baik dan memilki berbagai ide kreatif dalam menyusun bahan ajar dengan konteks kehidupan sehari-hari. Kata Kunci: pelatihan; bahan ajar; PMRI; CPNS 2019 [English]: One of the essential aspects to improve the quality of human resources is to improve the quality of education. But in reality, the teachers are less creative in planning, preparing, and make rich and innovative teaching contents which attract the students. Mostly, mathematics learning activities only present problems and formulas without regard to the inculcation of the concepts. Considering the number of prospective teachers in 2019, there is an opportunity to change the learning approach in schools to be more varied. The purpose of this community service activity is to provide an understanding and experience for prospective teachers about making teaching materials using the Indonesian Realistic Mathematics Approach (PMRI) in learning mathematics and producing teaching materials using the context of everyday life. This community service is carried out in the form of workshops that prioritizes practice, employing the on the job training method in which the training participants directly work under the guidance of experts. The results of this activity are teaching material in the form of student worksheets using the context of daily life which are then recorded and submitted for copyright so that they can be used by elementary school teachers widely. After the training, it was found that pre-service teachers had very good abilities and a variety of creative ideas in compiling teaching materials in the context of daily life.
