First, cultivate students' active learning and develop mathematical thinking consciousness. Nowadays, the classroom is no longer a simple process in which teachers ask students to listen below. The new concept requires that teachers are only the guides of students' learning. Classroom learning is an interactive process between teachers and students, which requires students to participate in the interactive process of teaching and learning boldly and actively. Only by actively exploring and actively learning can they learn new knowledge in math class. Therefore, teachers should first cultivate students' good habit of active learning. In primary school mathematics class, students are exposed to standardized mathematics problems, and it is not easy to realize the necessity of applying and learning mathematics in life. Therefore, as a teacher, we should consciously cultivate students' mathematical consciousness in teaching, so that students can be exposed to real-life mathematical problems, such as how to rent a car for an autumn outing, mathematical problems in shopping and so on. Make students realize that life is full of mathematics, cultivate the idea of observing, explaining and analyzing problems with mathematics, and solve practical problems with mathematical thinking.
