Research on the development of Islamic mathematic e-book as teaching materials at the elementary level is expected to help students in learning mathematics to improve students' conceptual understanding. Besides that, Islamic e-books are more effectively used in mathematics learning and become one of the innovations as a medium for learning mathematics. The research methodology uses the R & D method (ADDIE). This research was conducted at the SD IT Lentera Ilmu on July 17, 2019 until July 19, 2019. The subjects in this study were IV A classes totaling 30 students at SD IT Lentera Ilmu.
