E-books are different from e-books Electronic teaching materials are not simply scanned by traditional teaching materials and put on the learning network, but are paper-based main teaching materials based on People's Education Society. Deeply excavate and process the contents and knowledge points of teaching materials, and realize the digitalization of teaching materials and the intelligentization of interactive functions through scientific and intuitive audio, video and graphics. The electronic teaching materials of primary school mathematics make the teaching materials come alive on the network platform. Interact with textbooks among mice.

For example, there are erasers, nails, paper clips and a ruler in the textbook. In online electronic teaching materials, students can easily operate a ruler to measure.

Electronic teaching materials, in addition to really making the teaching materials "live", also consider students' personalized learning needs and design practical learning tools. Such as bookmarks, study notes, notes and study records. Among them, learners can add bookmarks to key page numbers, which is convenient for retrieval in the next study, record their study notes in real time, record the dribs and drabs of learning experience, and mark the key and difficult contents at the same time. The learning network will automatically generate learning records, which is convenient for learners to check their learning progress and make good data reserves for forming scientific learning evaluation in the future. Of course, there are also learning AIDS such as highlighters, erasers and palettes. If students gain something from the free experience of this unit and want to continue their studies, they can easily buy it by clicking the buy button.
