1October 9th 202 1, 1 1, more than 80 math teachers from Yangming Primary School, Jiaming Primary School, Xiangjiang Primary School and Sunshine Primary School attended the meeting.

First of all, I would like to give a welcome speech: leaders, teachers, Secretary Zhu of Yangming Primary School and President Chen of Jiaming Primary School, hello and welcome. Now we will start this joint film teaching and research.

The theme of this activity is: in order to understand the teaching project grinding activity, this activity has three agendas.

[If! Support list ]2. ? [endif] Speech by the Grinding Group

[If! Support list ]3. ? [endif] discussion

I hope that teachers can pay attention to the following questions in the process of listening to lectures:

[If! supportLists] 1。 ? [endif] Where to? Where will the students be taken in this class? Get to know the score. What do you know? What are the goals for students to understand?

[If! Support list ]2. ? [endif] How to get there? What activities did the teacher carry out to achieve the goal?

[If! Support list ]3. ? [endif] Have you arrived yet? Did the student's study really happen? Is there any evidence that children can understand the music score?

[If! Support list ]4. ? [endif] Next, let's give the stage to Mr. Mou Meng and the children in Class One, Grade Three.

Teacher Li Jing and Teacher Mou Meng spoke, and then entered the discussion session.

I have prepared: how to teach for understanding and think from three dimensions.

Three dimensions: depth, width and integrity

[If! supportLists] 1。 ? [endif] depth

What is depth and essence? Many students don't regard scores as numbers for a long time, which comes from a dynamic process, that is, getting one point. The average score here is the starting point of academic performance, and students should be more conscious in class. The meaning of the score is the understanding of the relationship between the whole and the parts, which embodies a way of thinking of "relationship understanding", which is also the reason why the score is more abstract.

[If! Support list ]2. ? [endif] width

In other words, students can establish multiple representations of scores, and the same mathematical concept, mathematical model and mathematical formula can be understood and expressed from multiple angles, and can also deepen their understanding.

[If! Support list ]3. ? Completeness

That is to grasp the whole, that is, as Li Xueqin said, we should see both trees and forests.

Overall grasp: the understanding of logarithm includes comparison size and operation. ...

Overall grasp 2: definition of score: (definition of number of shares, definition of quotient, definition of ratio)
