"If students want to master mathematics firmly, they must learn mathematics through inner creation and experience." "Experience" means that students feel, explore and apply in real life situations, so as to discover, understand and master knowledge. This class has always been guided by this concept. First of all, experience new knowledge in the situation of national conditions and children's songs, and experience the generality and conciseness of numbers expressed by letters in the comparison between Chinese and mathematics. Then I will experience it in the memory of old knowledge and life practice. Further understand and apply new knowledge. Finally, the exploration and experience of new knowledge in students' hands-on practice and cooperative operation has sublimated new knowledge and cultivated innovative consciousness.

Second, learn "living knowledge" and "dynamic" knowledge.

Catkin said well: "knowledge that is not strengthened and warmed by people's positive emotions will make people indifferent, because it can't touch people's heartstrings and will soon be forgotten." Therefore, under the strong spring breeze of the new curriculum concept, our teachers should reorganize and package the teaching materials so that students can learn energetic knowledge. Under the guidance of this theory, the situation of this class is to create problem situations with the help of multimedia, and guide students to carry out research-based learning and experiential learning (interest is the premise). For example, introduction, through the topic of "Olympic Games", is conducive to stimulating students' enthusiasm. For another example, this class is the first time that students use letters to represent numbers. To solve this difficulty, children's songs should be studied and discussed directly in the pre-class design, which is in line with students' cognitive characteristics, allowing them to explore and cooperate independently, experience the formation and demonstration process of laws personally, and change static mathematics into dynamic mathematics. "Therefore, the next result will naturally follow.

Third, give students the right to study and let them experience the fun of doing mathematics.

Give students a trust, and students will give you a miracle. In the process of learning, students are the masters of the classroom, and teachers are only the organizers of the classroom. Just give some guidance at the right time, give students enough time to observe, imagine space, express opportunities, respect students' opinions and don't make a final decision. The teaching of this class is to apply the life-related examples around students, so that students can be in the situation and give full play to their initiative. In addition, there are more opportunities for communication and cooperation between students in the whole class, especially in the last link, students are in high spirits and can discuss actively and freely, so that students can truly become the masters of the class and experience the fun of doing mathematics.

Fourth, insufficient.

How to grasp the "acceptance" and "release" of problems, students' problems will not be exactly the same, and how to deal with students' problems in the classroom, control the teaching rhythm and complete the teaching progress need to be explored in depth. How to guide students to ask questions is the key to exploration.

Verb (abbreviation of verb) explanation

The new classrooms are activity classrooms, discussion classrooms, cooperation classrooms, moral education classrooms and classrooms applying modern technology. Therefore, the new educational concept and new classroom under the new curriculum reform need to be cultivated by teachers and students together. Only by actively adapting to the new curriculum reform can we bring up new students.
