Mathematics is difficult to teach. Judging from the relevant public information, the content of "Hebei Education Edition" is relatively difficult, because Hebei Education Edition pays more attention to creating situations to strengthen the actual connection with life, and attaches importance to cultivating students' ability of collecting and processing information, analyzing and solving problems, expressing language and social activities, while Shandong Qingdao Edition is relatively small in capacity and relatively simple in arrangement. The illustrations of life situations are based on students' existing life experience, which is more suitable for children with urban life experience and less practical activities.
