1, the textbook is too difficult: the fifth grade mathematics textbook published by West Normal University is relatively difficult, and it is difficult for some students to understand and master, which leads to students' confusion and loss in the learning process and affects the learning effect.

2. The content of the textbook is not close to life: Mathematics is a subject closely related to life, but the content of the fifth-grade mathematics textbook published by West Normal University is not close to students' daily life, which makes it difficult for students to apply mathematics knowledge to real life and understand its practical significance.
