Abstract
Math lessons are abstract and complex for students to understand, so that the teachers need instructional media to develop by using technology to help their students get deep learning. This study aimed to validate the instructional media to teach the Pythagorean theorem and describe the students and the teachers' responses to the instructional media. The researchers implemented the ADDIE model in this study. The sample comprised 30 students in 7th grade and 56 teachers. The process of validation involved ten academics. The results of this study showed that the instructional material could be used. The results also showed that the students were happier when the teachers used the instructional media in the classroom.
