Decimal multiplication is new knowledge, but almost all children can calculate independently. The reason is that grade five students have certain learning experience and methods, and have enough knowledge accumulation. Therefore, I think it's better to do more than one thing. Let the students do the math by themselves, and then talk about how to do it.

Advantages: The whole class has clear ideas, compact links, outstanding difficulties and reasonable design. Students' classroom habits are very good, everyone can actively participate in the classroom, and the classroom effect is good.

Teachers are persuasive in teaching new knowledge, so that students can learn effortlessly, give full play to students' initiative, design and guide teaching well, and make students realize the connection between students and life.

Disadvantages: students' enthusiasm in class is not enough, students' divergent thinking ability and active questioning ability need to be improved, and some contents are missing.

Suggestion: Strengthen the training of teachers' basic skills, learn with an open mind, improve constantly, and strive to become the backbone teachers of the school. If multimedia can be used to assist teaching, the explanation and consolidation of knowledge points will be more effective.

Advantages: the teaching language is capable, the class rhythm is compact, the thinking is clear, and the combination of in-class management methods is enlightening.

Disadvantages: there is no blackboard writing, the number of words in the courseware is too small, and the class speed is too fast.

Advantages: the class links are complete and the difficulties are clear.

Disadvantages: Students didn't give positive language when they answered correctly, and finally summed it up too quickly.

Advantages: the class state is relatively calm and stable. Introduce new lessons and get to the point.

Disadvantages: (1) The language in class is too dull and has no ups and downs. Lack of language to encourage students. (2) There is a lack of group discussion in the classroom, which fails to apply the concept that students are the masters of the classroom to the actual classroom.
