Correct Qur'anic reading requires children to recognize not only letters and vowels but also the sound rules that appear when nun sukun or tanwin meets particular letters. This community service activity aimed to improve children's conceptual understanding and reading application of nun sukun and tanwin rules at the Baiturrahman Qur'anic Education Center in Nagari Sungai Taleh. The program used a Training and Workshop approach consisting of initial reading observation, concise concept explanation, classification of izhar, idgham with and without ghunnah, iqlab, and ikhfa, facilitator modeling, guided examples on a whiteboard, group repetition, individual reading practice, and formative correction. Data were collected through observation notes, oral responses, reading demonstrations, and photographic documentation. Results show that the structured visual and oral exercises helped children distinguish the main categories, mention selected letters, and apply the rules to examples under guidance. The workshop also encouraged children to answer questions, read in turn, listen to peers, and accept immediate correction. The program's contribution is a simple, low-cost tajwid learning pattern that combines visual grouping, auditory modeling, repetition, and direct application to Qur'anic passages. Because standardized pre-test and post-test scores were not available, improvement is reported as a qualitative indication based on participation and reading practice. Continued short exercises, color-coded materials, and individual progress records are recommended for sustainability.
