"Knowledge in Collocation" is the content of the first volume of Grade Three, and the main scene in the textbook is side dishes. Through the gradual deepening of this situational activity, students' orderly thinking ability is cultivated, and their interest in learning mathematics and awareness of solving problems with mathematical methods are cultivated. First, on the basis of allowing students to think independently, conduct group communication and feedback from the whole class. When the students finish this activity, I will give guidance. I found that most students have no difficulties, only a few students have some difficulties, and this problem has also been solved in group communication and class communication. Second, when students actively think and dare to express their different ideas, when students put different solutions in front of me, it is interesting that when students exchange ideas, students follow a certain order. Third, the application of methods and the extension of practical teaching, I let students do it independently. On the basis of students' independent thinking, group communication and class feedback, I mainly let students say that it is difficult to transfer from catering knowledge to walking, but this problem has also been solved in group communication and class communication, especially when students demonstrate how to walk in front of the physical projector, which is very orderly. I added another road between the school and the Children's Palace, called F road.

In short, in this class, I will start from the scenes around students, guide students to think positively through questions, pay attention to the connection with students' real life, narrow the distance between mathematics and students, and let students feel that mathematics teaching is everywhere in their lives. I pay attention to the following issues:

1. Closely connect with students' real life, provide students with space for exploration, create more practical opportunities for students, let students play freely, guide students to explore independently through their own practical operations, discover mathematics, feel mathematics and experience mathematics in exploration, and greatly mobilize students' learning enthusiasm.

2. Pay attention to students' learning process, actively encourage students to think independently, carry out group cooperative learning on the basis of students' independent thinking, and then carry out class exchange learning. Teachers leave time and space for students to study and create a relaxed, democratic and harmonious atmosphere for students. Students actively participate in research and study. Teachers pay attention to entering students, exploring and communicating with students, and helping students to remove obstacles when they have problems.

3. Pay attention to the cultivation of students' thinking ability and oral expression ability, and guide students to transition from disorderly thinking to orderly thinking through comparative analysis, so that students' thinking is meticulous and orderly.
