1. Prepare lessons before class. Before each teaching, the first thing to do is to prepare lessons, which will directly affect the fluency and effect of each teaching. Especially in the first class, because I don't know what kind of students and parents I will face, I should be fully prepared, because the success of the first class will make the later work much smoother. Of course, no matter which class you attend, you should prepare your lessons carefully, because only by being fully prepared can you speak the class better. At the same time, with good lesson preparation, the effect of lectures is relatively improved, which is conducive to the transfer of knowledge and easier for children to accept. 2. Understand the students' saying: "Know yourself and know yourself, and you will be invincible." Similarly, in the process of tutoring, understanding students is also essential. First of all, we should make clear the students' cultural level, that is, the knowledge level of the students you teach, so as to suit the remedy to the case and determine the difficulty of the teaching content. Secondly, pay attention to understand students' personality characteristics, so as to analyze specific problems. For example, some students are naughty and may not like learning. At this time, it is necessary to adopt appropriate methods to cultivate their interest in learning; But some students are quiet. At this time, we should pay attention to stimulating his (her) thinking, thinking more about problems and so on. Third, know the advantages and disadvantages of students in learning in time so as to choose teaching in a targeted way. Feeling every progress of students and encouraging them in time are of great help to improve their interest in learning. 3, pay attention to stimulate students' interest in learning, no matter what you do, as long as you are interested, you can take things seriously and do things well. Suhomlinski said: "In people's minds, there is a deep-rooted need to feel like a discoverer, researcher and explorer, but in the spiritual world of children, this need is particularly strong." If teachers want to guide students into research-based learning, they must stimulate students' strong desire to explore and make them have strong internal motivation. 4. Pay attention to the fact that mathematics comes from life. Only by proceeding from reality can it be easy to operate and understand. Modern educational theory holds that mathematics comes from life, which is full of mathematics, and mathematics teaching should be applied to real life. Therefore, mathematics teachers should consciously guide students to communicate the connection between specific problems in life and related mathematics problems, stimulate students' curiosity in learning mathematics with the help of concrete examples in real life that students are familiar with, discover mathematics problems in life, solve practical problems with the analysis they have learned, and guide students to conduct research-based learning.
