1. Students, we just learned how to multiply multiple numbers by one number. In this lesson, we will sort out and review this part of the content. (blackboard writing project)?

(1) What have we learned in this unit? (2) What did you learn from this unit? ?

2. Students study. ?

3. Communication and reporting within the group?

Default:?

In this unit, we learned oral arithmetic and written arithmetic.

We also learned about estimation. ?

Written multiplication includes carry multiplication and non-carry multiplication.

Written multiplication also includes multiplication with zeros in the middle and at the end of the factor. ?

In order to see clearly what we have learned in this unit, we can string this knowledge together in some form, such as drawing a knowledge tree. Shall we finish this knowledge tree together? Teachers and students work together to complete the knowledge tree (the blackboard presents this part of the knowledge structure diagram). The design aims to guide students to talk about the gains of learning, including knowledge, skills, emotional attitudes, etc., so that students can learn to sort out what they have learned and deepen their understanding of knowledge. Make students form a systematic mathematical cognitive structure in their minds, so as to improve their mastery of this unit of knowledge.
