After listening to a calculation class given by teacher *, I was deeply touched.

1. Strengthen the connection between knowledge and bring forth the new.

Teacher Feng made full preparations for students to learn new knowledge by reviewing at the beginning of the class. Mathematics learning is characterized by gradual and spiral rise, just like taking stairs. With a foundation, we can continue to move to a higher level. Divider is the division of decimals, and the key point is the division into integers. So the calculation of division with integer divisor is the basis of learning division with decimal divisor. Therefore, it is very necessary to review before class, and at the same time, let students discover the invariable law of quotient and pave the way for learning new lessons.

2. Give full play to students' initiative and guide them to explore actively.

It is better to teach people to fish than to teach them to fish. When exploring new knowledge, Mr. Feng gives full play to students' initiative. Through observing, comparing, connecting with old knowledge, timely guiding, and constantly trying, he guides students to organize and guide them to use old knowledge to acquire new knowledge, and permeates the mathematical idea of "conversion" into teaching, so that students can appreciate this mathematical idea carefully in the diversification of algorithms and find universally applicable methods from it.

3. Teacher Feng spoke very well at the key points, such as the decimal point of quotient should be aligned with the decimal point after dividend is moved, and the dividend digit is not enough, so add 0.

4. The exercises are also targeted, which helps students to understand the key points and difficulties of this lesson.

Suggestion: When practicing again, you can design several problems in life, so that students can better understand the importance of what they have learned, not just calculation.
