Mathematics application consciousness in life situation.
Our life is full of math problems, and everyone will encounter math problems in real life. Our students are no exception. They will use the knowledge of "number" to solve many life problems from an early age. For example, students should know which floor they live on, how many trees are around the building, how many people are in their family, how many students are in the class, how many toys they have and so on. Therefore, teachers must be good at abstracting mathematical problems from students' real life, so that students can feel that mathematics is around them and understand the practicality of mathematical knowledge in real life, thus stimulating students' strong interest in learning mathematical knowledge and cultivating students' awareness of mathematical application.

In order to achieve this teaching goal, I attach great importance to cultivating students' awareness of applying mathematical problems in life situations. For example, I want to solve the application of mathematical knowledge in students' labor. In a class cleaning work, I found that some desks and chairs were loose. I immediately seized the opportunity and asked the students, "Who can use the mathematics knowledge we have learned to come up with a good solution to the problem of loose tables and chairs?" Let the tables and chairs stop shaking so that we can sit comfortably. "Students began to think about how to make tables and chairs stable. After a while, a student thought of using the learned "triangle stability" to form a triangle for the chair, thus making the chair stable. After discussion, everyone agreed that it is the best way to fix the swaying tables and chairs by using the stability of the triangle. Seeing that students can use math knowledge flexibly, I quickly went to the school storage room to get tools for students to repair, and then shook them to see if they would shake them again. After "learning-thinking-application one by one"
The process of "practice" makes students deeply impressed with the mathematical knowledge in their minds and can apply it, which naturally achieves twice the result with half the effort.
The key to grasping the scene is that our teacher has a heart and the teacher has a heart. There are examples of applying mathematical knowledge everywhere in real life. After teaching the meaning of comparison, I let the students know a lot about their own interesting comparisons. The ratio of body weight to blood is about l3: 1. The ratio of height to foot length is about 7:l, and so on. When students understand these ratios, I will ask them, "Students, do you know these interesting ratios? Do you know what these ratios can be used for? " As soon as I mentioned this question, my classmates found it very interesting and immediately thought of it. After careful consideration, some students said, "As long as you weigh yourself, you can immediately calculate the weight of your blood." Some students said, "Public security personnel can estimate the height of bad people by footprints." In this way, students' interest in learning mathematics is greatly improved.
