First, create a situation to stimulate interest. Mr. Tao Xingzhi once said: "The best condition for exerting learning potential is democracy." In teaching, teachers should respect, understand and care for every student. Take yourself as a "special" member of the class, participate in students' learning activities, get along and communicate with students sincerely and frankly, firmly believe that students are the main body of innovation, and create a sincere and understanding atmosphere for students through their artistic service and love. Who doesn't want to learn such a learning environment? Second, encourage questions and stimulate interest. "Learning begins with thinking, and thinking begins with doubt". "Doubt" is a clue to stimulate students' interest in learning. Asking questions can make students confused and have a strong desire to solve problems. In the teaching process, teachers should consciously set questions in preparing lessons, attending lectures and assigning homework, so that students can creatively solve problems through independent thinking and analysis. For example, after teaching the meaning of comparison, some students asked, "Can three numbers be compared? Does the comparison of three numbers also mean the division of three numbers? " Students can ask such questions because they are interested in mathematics. In the long run, they will certainly benefit a lot. Third, contact the reality of life and stimulate interest. Mathematics itself has strong practicality and application. It comes from production and life practice, is abstract from life, and serves life everywhere. Introducing the outlook on life into classroom teaching conforms to the discipline characteristics of mathematics teaching and students' cognitive rules, which can transform the abstract into concrete and make students have a strong interest in mathematics. Fourth, carry out math activities to enhance interest. There are many interesting laws in mathematics, and it is difficult for students to understand them simply from mathematics textbooks. To cultivate students' interest in mathematics, we should also combine the contents of teaching materials, carry out extracurricular activities and expand mathematics knowledge.
