At present, students' expressive ability is getting worse and worse. The main reasons are as follows: (1) Due to students' limited knowledge level and different understanding abilities, teachers are eager to let students tell the correct answers in the teaching process, and only pay attention to a few "top students", so that most students become accompanying guests. In the long run, most people will not get exercise, and their language skills will naturally be poor. (2) Some students are introverted, shy and unwilling to speak in public. (3) When some students make mistakes, they will be laughed at by quite a few students, which will make them lose the courage to speak. Therefore, according to the different situations of students, we should constantly encourage and cultivate students' healthy and positive speaking mentality, let them say whatever they want, and stimulate students' desire to speak. We should have different requirements for students at different levels, encourage students to speak boldly and give all students the opportunity to speak as much as possible.

They can be trained from the following two aspects: 1. Encourage students to reason.

Cultivating students' computing ability is one of the purposes of mathematics teaching. The focus of computational mathematics is to master the calculation rules on the basis of understanding arithmetic. Students seem to understand an arithmetic, and whether they really understand it depends on whether they can express it clearly. The process of letting students dictate arithmetic and rules is also the process of students' in-depth understanding and mastery.
