Pupils tend to rely on teachers, who are authoritative for a long time, and dare not question and ask questions, which has a bad influence on students' learning and growth. For example, primary school students who are naturally lively and active, like uncut wood, have their own personality. Rigid teaching methods and unified answers, like a cold axe, cut off students' thirst for knowledge, curiosity and imagination, making them uninspired and uncreative. The use of learning tools can focus on stimulating students' interest and thirst for knowledge, and get twice the result with half the effort.

(B) the use of learning AIDS is conducive to the cultivation of practical ability.

The cultivation of students' practical ability cannot be divorced from real life. Learning tools are like a bridge of communication, which can guide students to link the study of abstract mathematical knowledge with practical problems in real life, teach students to solve practical problems with mathematical knowledge, and consciously cultivate students' practical thinking.

(C) the use of learning AIDS is conducive to the cultivation of the status of learning subject.

Inquiry consciousness is an essential spiritual condition for human cognitive activities. Pupils in the information age have a wide range of knowledge. Under the guidance of teachers, with the help of learning tools to explore and discover, mastering mathematical knowledge is conducive to students' better understanding of abstract knowledge. At the same time, the use of learning tools strengthens the interaction between teachers and students, so that students can actively absorb knowledge instead of passively accepting it, which is helpful to change the one-way indoctrination teaching situation with teachers as the mainstay.

(D) The use of learning AIDS is conducive to the cultivation of cooperative consciousness.

Cooperation plays an important role in human society, whether in study or work. In teaching, the way of group teaching and the means of operating learning tools can promote the communication between students and enhance their awareness of cooperative learning.
