The availability of adequate teaching materials, of course, can help students master these abilities. However, this has not received more attention from educators. This study aims to develop textbooks that are valid, practical, and effective for building students' mathematical literacy skills. this type of research is Research and Development (R&D). The stages of developing the textbook used to refer to the ADDIE model. The research instruments used in data collection were validation sheets, observation sheets on the implementation of textbooks, student response questionnaires, teacher response questionnaires, student activity observation sheets, observation sheets on the teacher's ability to manage learning, and tests of mathematical literacy skills. The data obtained were analyzed using data analysis techniques for validity, practicality, and effectiveness. The study found that the developed textbook met the validity criteria with a very valid category. The results of the practicality analysis were obtained based on the results of the teacher's response analysis in the very good response category, the results of the analysis of the teacher's ability to manage learning in the good category, and the results of the analysis of the implementation of textbooks in the fully implemented category. The results of the analysis of the effectiveness criteria were obtained based on the results of the student response questionnaire analysis in the good category, the results of the analysis of student activities during the learning process in the good category, and the results of the analysis of the mathematical literacy ability test with a completeness of 74%. The developed textbooks can facilitate and adequately build students' mathematical literacy skills because they meet the criteria of validity, practicality, and effectiveness.
