Teaching is regular, but there is no fixed law. The most important thing is that there are laws to follow, and the wonderful thing is that there are laws to follow. Because primary school students are curious, active, interested in short time and poor persistence, the classroom learning effect is often affected. Therefore, the courseware aided by information technology is not only used to convey the teaching content, but also to change the traditional teaching methods and learning methods, which is conducive to adjusting the classroom atmosphere, creating learning situations and stimulating students' interest in learning mathematics.

Second, with the help of information technology, we can turn abstraction into intuition and promote students' understanding of mathematical knowledge.

Pupils have a narrow knowledge of life, little perceptual knowledge and weak abstract thinking ability. Using information technology can intuitively show the whole process, give students an immersive feeling, build a bridge from visual thinking to abstract thinking for them to learn mathematics knowledge, and help them understand knowledge.

Third, with the help of information technology, let students feel the process of knowledge formation.
