"Time" is an abstract concept. On the basis of students' initial understanding of some time, this lesson is carried out according to "several times" and "several times". It is through the comparison of two things that students can make clear who is compared with whom, who is a replica, and who has such a replica several times as much as who. This leads to the new knowledge of "how many times is a number"

In the teaching of this lesson, I paid attention to the following points:

1, change teaching methods, put teachers and students on an equal footing, put down teachers' airs, become students' partners in activities and learning, and make students the main body of learning. The role of teachers has changed, showing a brand-new concept of classroom teaching.

2. Creating situations stimulates students' interest in learning. Einstein once said: "Interest is the best teacher". Interest is also the key to students' hearts. In front of things of interest, students are very excited, devoted and quick-thinking ... let students love and enjoy learning, turn interest into motivation and make the classroom come alive. Using the teaching mode of "independent inquiry", students can use their brains, move their mouths and take part in learning with high enthusiasm.

According to students' age characteristics, psychological characteristics, cognitive rules and thinking development, as well as the teaching content of this class, I designed this link in teaching, including (I can talk, I am a small teacher, I can calculate, I am an intelligent bridge) to stimulate students' interest in learning and let them have feelings of loving mathematics.
