In the context of modern education, developing mathematical communication skills for primary school students has become an urgent requirement. Mathematical communication skills do not only help students understand and solve problems effectively, but also create conditions for them to practice the skill of communicating ideas clearly and coherently. Thereby, students can discuss, debate, and express their mathematical views with teachers as well as friends, thereby forming critical thinking and the ability to express mathematical ideas logically.In the context of modern education, developing mathematical communication skills for primary school students has become an urgent requirement.
