First, be good at learning textbooks and using good examples.

Teaching divides cakes around the examples provided by the teaching materials, creates specific situations, stimulates students' interest in learning, and promotes students to carry out learning activities effectively. At the same time, the contents of the teaching materials were carefully selected, combined and recreated, and the animated courseware with cake was made, and the teaching materials were used creatively, which reflected the use of the teaching materials rather than being rigid.

Second, we have a profound understanding of the new curriculum concept and a proper grasp of teaching methods.

Using situational teaching method, observation and discovery method, cooperative inquiry method and example teaching method, we create a relaxed and harmonious learning atmosphere, which embodies the "student-centered teaching thought". It trains students to cooperate and communicate with each other. Therefore, the classroom structure is compact, logical and excessively fresh and natural.

Third, acquire new knowledge through practical operation.

In this class, the teacher asks the students to divide the plates fully, so that they can constantly generate and solve problems in their own attempts, explorations, guesses and thinking, and then generate new problems, leaving room for students to operate.

In teaching, the teacher guides students to divide a point equally with three round pieces of paper, and makes students think: How many ways can three cakes be divided equally among four children? Ask the students to get two different points through hands-on operation, and extend two meanings, namely 1 cake and 3 cakes. Through this process, students fully understand arithmetic.

4. Accurately grasp the teaching key points of Fraction and Division, and highlight the key points through the teaching process of calculating, observing, discovering laws, summarizing laws and practicing them.

1, cooperative inquiry is well grasped and the operation is in place.

There are two ways to divide the cake: three cakes are divided equally among four people, and how many pieces are each divided? 3÷4 (block) students have experienced conjecture and verification. The teacher's way of dealing with it is to hand over the classroom to the students, which is a good teaching method and worth learning.

2. Practice standards are in place.

The teacher's teaching design combines the key points and difficulties of this class and meets the requirements of this part of teaching. In different levels of practice, we should construct a knowledge framework, realize the gradual deepening of mathematical thought, and let students experience the happiness of success.

3, expand and extend, with scale.

Teachers can grasp the teaching materials as a whole, encourage students to actively participate in teaching activities, let students solve their own problems, let students explore their own methods, let students discover their own laws and let students acquire their own knowledge. In the classroom, students are given enough time to think and space for activities. At the same time, students have the opportunity to express themselves and successful experiences, cultivate their self-awareness and give full play to their main role.

Grasp the teaching key accurately, and highlight the teaching process. At the same time, students' dominant position is highlighted in this teaching link: students themselves get the relationship between score and division through cooperative exploration, and then teachers grasp this key point and consolidate it. Clear teaching clues make the classroom content compact and orderly.

4. The process of imparting new knowledge pays attention to students' self-inquiry.

For example, when learning the relationship between fractions and division, ask students to discuss in groups and tell the relationship between them. When exploring the mutual variation of false marks and scores, teachers let students observe and compare the methods in textbooks by themselves, and then let students summarize the mutual variation of false marks and scores, which cultivates students' ability to analyze problems in this link.
