This passage correctly summarizes the relationship between number and shape. An educator once said: "Children's wisdom is at your fingertips." Therefore, in mathematics teaching, we should mobilize children's various senses, let children experience the attributes of a certain mathematical concept independently and happily, and explore the laws of mathematical operation in the interaction with materials.
Usually in the collective teaching activities of mathematics:
It is often found that many children have the mentality of' conformity'. It is' conformity' and follow everyone. If others say so, he (she) will follow suit, and if others do so, he (she) will follow suit. On the surface, it seems that they also understand these contents, but in fact, as soon as they arrive at the stage of operational activities, problems appear immediately. Therefore, it depends on the operation stage to test whether children really understand or master the content of an activity.
In the operation activities, children use their hands and brains, find problems independently, learn actively, taste the fun of exploring knowledge, solve problems, and achieve the goal of wisdom at your fingertips. Therefore, in mathematics activities, teachers should pay more attention to the process of children's hands-on operation. Only in the process of children's hands-on operation can we understand children's understanding of the content more clearly. Pay attention to the operation process in the activity. You should carefully design this process. You can't go through the motions and count it.
When designing homework, teachers should closely focus on teaching requirements, stipulate homework procedures and rules, design homework steps and problems that children need to observe and think about. Only through comparative observation can children abstract the decomposition components, and giving children enough operation time is also an important condition to ensure the success of the operation.
