1. Let the students "feel at ease": One or two minutes before class, the students' hearts are still in the excited state of playing between classes. It is necessary for students to adjust themselves during this time and calm down before class in order to concentrate. Teachers in all subjects can cooperate well to cultivate students' habit of preparing school supplies for the next class before going to activities. At the beginning of the class, when the students were very excited, the teacher said that shouting had no effect. You can clap your hands rhythmically, and the students clap three times together and then sit down.

2. Make students "alert": To be "alert", you must listen and remember. Therefore, the key content of each class allows students to repeat the teacher's speech or the students' speech, and can also do some listening and calculation exercises frequently to cultivate students' listening attention.

3. Let students "know": If you want to make it back, you have to understand that students just listen and don't think about it, which means they don't listen. In class, we should pay attention to guiding students to talk about their own views and ideas after listening to other people's speeches, and find out where others' speeches are good, wrong or need to be supplemented.

4. Create a lively and relaxed listening atmosphere under the premise of ensuring classroom discipline: the new curriculum does not advocate the very rigid teaching form in the past. As long as students can concentrate on their studies, teachers don't have to be strict about whether students are sitting correctly. In class, they can take some forms of deskmate communication and group cooperation, operate or discuss in cooperation and interact with teachers and students. Of course, in cooperation, teachers should pay attention to the role distribution and assign each team member a post, so everyone has something to do. Before cooperation, teachers should make clear the requirements of cooperation, which will certainly stimulate students' sense of responsibility and participation, and avoid group cooperation becoming a mere formality. In this way, students' thinking is stimulated, and under the guidance of teachers, they will be more willing to listen to the learning methods of mathematics in the second grade of primary school.

5. Reading and writing: It is common for students to make mistakes in reading and doing exercises. The calculation is simple, students are not unable to do it, but careless and not serious. How can we form the habit of being careful and earnest? I think Liu Yiting, a "Harvard girl", was trained by her mother in a very effective way. Every time, she finishes the training of copying phone numbers in one minute, with her left finger and her right hand. After copying, she compared and the parents took notes. About ten minutes of training every day.
