This study aims to determine the level of validity of teaching material supplements on the subject of the digestive system. This type of research is research and development (R&D) using the ADDIE model but modified only to the development stage. The results showed that the results of the validation of teaching material supplements, content validation, were included in the very valid category with a percentage of 9o% and the results of construct validation showed that teaching material supplements were also included in the very valid category, with a percentage of 94%. Thus the teaching material supplement is included in the very valid category and can be used as a supplement to the digestive system teaching material.
