Developed teaching materials should have the good criteria such as valid, practical and effective. The purpose of this study is to determine the level of validity and practicality of teaching materials developed. This research method uses a Mc Kenney's development model, which is devoted to stage 2, namely: prototyping phase: expert test and practice test by students and teachers. Based on the results of the validity test obtained data that teaching materials based on character building with the discovery learning modelare in the category of valid with an average score of 3.7 and it is in a category very valid. Furthermore, the stage of practicality is done by giving questionnaire to teachers and students.
