Life is inseparable from mathematics, and mathematics is inseparable from life. Mathematical knowledge comes from life and ultimately serves life. In teaching, it is required to start from the life world that students are familiar with, choose things around students, ask relevant math questions, and stimulate students' learning motivation. Mathematics teaching should start from students' existing knowledge and experience, so that students can participate in specific teaching activities and gain some experience.

1. Mathematics comes from life and creates a relaxed and happy learning situation.

2. Bring life scenes into the classroom to improve the efficiency of mathematics teaching.

3. Facing life, guide students to use mathematical knowledge to carry out practical activities.

In a word, mathematics can not be separated from life, and there is mathematics everywhere in life. Mathematics comes from life and is applied to life. Knowledge that comes from life and belongs to life is valuable knowledge. Linking mathematics with life, let students feel the true meaning of mathematics unconsciously.
