Primary school students to learn the concept of mathematics, often with specific facts and existing experience, from perceptions, appearances and other sensory material obtained summed up the concept of mathematics. Therefore, the actual contact with students should run through the entire process of teaching mathematics concepts. Grasp the specific guidance, speaking, practice, with four links.
