一、教学中让学生理解数学概念1.直观形象地引入概念数学概念比较抽象,而小学生,特别是低年级小学生,由于年龄、知识和生活的局限,其思维处在以具体形象思维为主的阶段。认识一个事物、理解一个数学道理,主要是凭借事物的具体形象。因此,教师在数学概念教学的过程中,一定要做到细心、耐心,尽量从学生日常生活中所熟悉的事物引入。这样,学生学起来就有兴趣,思考的积极性就会提高。2.运用旧知识引出新概念 First, the teaching of students to understand the concept of mathematics 1. Intuitive introduction of concepts Mathematical concepts more abstract, and pupils, especially the lower primary school pupils, because of age, knowledge and life limitations, the thinking in a concrete image-based thinking stage. Understand a thing, understand a mathematical truth, mainly by virtue of the specific image of things.
