Abstract: This development research aims to produce mathematics teaching materials assisted by PowerPoint media that meet valid, practical and effective criteria for improving literacy and numeracy skills in statistics material. Researchers took the research location at SMK Negeri 1 Tondano with the subject of phase E Health Services B for the 2023/2024 academic year. The design of this research is the ADDIE Research Develop Model (Branch, 2009). Development can be declared to be terminated if the development product meets the criteria of being valid, practical and effective according to the criteria (Nieveen, 1999). The instruments used to obtain data regarding these criteria are interviews, validation sheets, teacher ability observation sheets, student response questionnaires and student learning outcomes tests. The results of the research show that it is valid based on the results of the validation of teaching materials, namely 96.47% and the results of the validation of the learning outcomes test, namely 95.87%, both of which are in the very high predicate. The results of the interview validation were 93.13%, the results of the validation of the teacher ability observation sheet were 95%, and the results of the validation of the student response questionnaire were 91.25%, all three of which were ranked very high. The practicality of the teaching materials developed is based on the teacher's level of ability which is taken through observational data assessed by the observer, getting a total average score of 4.77 with very high criteria. Meanwhile, the effectiveness of teaching materials is based on the level of student response and the completeness of classical learning outcomes. For students' responses to the products developed, researchers received a positive response of 91.79% and classical completion of 84.62%, which is in very good criteria. Based on these data, according to the criteria, it can be concluded that the teaching materials developed to improve students' literacy and numeracy skills meet the valid, practical and effective categories.
