Be familiar with the teaching materials when preparing lessons.

1. Establish the overall concept of the whole textbook. When I get the textbook and read the whole book, I usually finish the exercises of the whole book, and I can get the right scale when I explain the textbook, so I can be more skilled when I explain the exercises and new lessons. On the basis of being familiar with the textbook, I can understand the position of this textbook in the whole primary school mathematics textbook and the relationship between the two textbooks, and grasp the progress of key and difficult points.

2. Thoroughly understand the contents of the section. Determine the teaching objectives of each class and organize teaching around the objectives. Strive to achieve a single goal, learn a lesson, and avoid blind fighting.

3. Understand the basic situation of students. Understand the learning situation of top students, average students and underachievers.

4. Understand students' mastery of knowledge and skills. Consider what students haven't touched, what they have learned, what they haven't mastered, how many people haven't mastered, what proportion they have, and whether to arrange a review session in the next class.

Teachers should also think about the questions to be asked in each class, and each question should achieve the teaching purpose. They should make full use of the 40 minutes of class to prepare lessons for the questions that students may answer when preparing lessons. Teachers should think carefully about strategies.
