1, import part. In order to let the students naturally enter the theme of this lesson, I used an animated video as an introduction. This video describes two students playing a shooting game. Whoever shoots more will win the game. After the video, I asked the students to answer questions according to the video content, which led to the theme of this lesson.

2. Teaching process. First of all, I showed a form of 100 integral in kind, and explained the meaning of each column in the form to the students. Then, I showed them the report forms of two students, and asked them to find out which student's score was higher through observation, comparison and group discussion. In this session, I particularly emphasized the methods and steps of comparison, and the students also actively participated in it, actively answering questions and sharing opinions.

3. Interactive link. I designed some questions, such as: "How to compare the scores of two students?" "What should we do if two students get the same marks?" Wait a minute. These questions aim to guide students to think deeply about comparative methods and encourage them to speak actively and express their views.

4. Summary and feedback. At the end of the course, I summarized the knowledge points of this lesson and asked students to give feedback on their mastery of the content of this lesson. Students said that this course taught them how to compare sizes and can use this skill in their lives.

Mathematics learning skills in the second grade;

1, understand the concept. When learning mathematics, we should pay attention to understanding concepts rather than memorizing formulas and methods. Only by truly understanding mathematical concepts can we use mathematical concepts flexibly to solve problems.

2. Practice basic operations. The core of senior two mathematics is four operations of addition, subtraction, multiplication and division. Children should master these basic operations through a lot of practice, so as to improve the calculation speed and accuracy.

3. Do more application problems. Application problem is an important link to cultivate children's practical problem-solving ability. By doing application problems, children can learn to use mathematical knowledge to solve problems in real life.

4. Do more oral arithmetic training. Oral arithmetic is an effective way to cultivate children's fast computing ability. Children can improve the speed and accuracy of calculation through oral arithmetic training.

5. Pay attention to thinking training. Mathematics is a subject that needs thinking, and children should pay attention to cultivating their thinking ability. Children's thinking ability can be exercised by doing some interesting math problems, such as Sudoku and logical reasoning.

6. Use more tools. In mathematics learning, some auxiliary tools can be used to help children better understand and master knowledge, such as calculators and geometry tools.
