This study aims to develop a Riau cultural literacy module for elementary school students' narrative text writing skills that is valid, practical, and feasible to use. The method used in this study is Research and Development (R&D) with a 4D development model, which includes four stages: Define (needs analysis), Design (design), Development (development), and Disseminate (dissemination). The developed module was validated by three experts, namely teaching material experts, material experts, and language experts. Meanwhile, the practicality aspect was assessed through a practicality questionnaire given to teachers and students during a limited trial. Data collection techniques in this study include interviews, observations, and questionnaires. The data obtained were analyzed using quantitative analysis techniques and qualitative descriptions. The validation results showed that the developed teaching materials met the valid criteria with an average percentage of 96.1%. Meanwhile, the level of practicality of teaching materials based on the teacher's practicality questionnaire reached 83.3% with the category of "very practical," and the student's practicality questionnaire obtained a result of 90.3% with the category of "very practical". Based on the results of the validation and practicality test, it can be concluded that the elementary school Riau cultural literacy module has met the valid and practical criteria, so it is suitable for use in learning.
