This study focuses on the elementary school teachers’ thoughts about practices for applied digital mathematics texts in reading activities for high grade elementary school students, understanding the assisting values and using practices about the applications of digital mathematics reading texts integrated into elementary school students reading development in mathematics reading activities of reading motivation, reading comprehension, and communicative interaction. The researcher employs observation and interview to deal with high grade elementary school students’ educational field of digital mathematics reading texts assisted reading instructions, and indicates the assisting values of the development of reading comprehension of high grade elementary school students by digital mathematics reading texts.The results indicate that elementary school teachers agree the values of applied digital mathematics reading texts on the dimensions of digital reading learning, reading cognition, and reading interactions for elementary school students. With the construction of friendly and appropriate digital reading learning situations by digital mathematics reading texts, teachers can enlighten elementary school students' emergent literacy and digital mathematics reading comprehension, and improve reading communication and interaction between teacher-student and elementary school students. Finally, the researcher provides the understanding of academic research community and digital mathematics education relevant authorities to construct applied digital mathematics reading texts in digital reading instructions for elementary school students and develop digital mathematics reading educational professional innovative strategies as the choice of reference.
