小学数学中的概念大都有一定的联系,常常是这个概念从另一个概念发展而来,同时又给以后的概念学习打下基础。基础打不好,概念不清楚,相应的技能、技巧就不易形成。为使学生掌握清晰的数学概念,教师不仅要讲清概念的内容,还要对学生进行多种训练,加深学生对概念的理解。 The concept of elementary mathematics mostly has some connection, often this concept evolved from another concept, while laying the foundation for future concept learning. Basis to play well, the concept is not clear, the corresponding skills, skills is not easy to form. In order to equip students with a clear mathematical concept, teachers should not only clarify the concept of content, but also conduct a variety of training for students to deepen students' understanding of concepts.
