Mathematics is the soul of thinking. Learning mathematics can improve students' thinking ability. As a teacher, we must be good at using mathematics to guide students to observe all things in life, use mathematical thinking to think about problems, and use mathematical perspectives to understand the world. Teachers should use flexible teaching methods to attract students into mathematics teaching classrooms, understand the relationship between mathematics and life, so that students have an interest in mathematics, so as to activate the classroom atmosphere and improve classroom teaching efficiency. Of course, it is not enough to connect students' mathematics learning closely with their lives. In this era of information technology explosion, we should encourage modern information technology to enter elementary school mathematics classrooms, and enrich mathematics classrooms through the characteristics of modern information technology in graphics, text, sound and shapes. Letting information technology assist mathematics teaching is particularly important for the implementation of the new curriculum reform.
