数学概念是反映数学对象的本质属性和特征的思维形式数学概念是反映数学对象的本质属性和特征的思维形式,是构成数学的基本元。因此,概念教学是数学课堂教学的核心教学是数学课堂教学的核心。本文以“认识比”教学为例,谈如何有效进行概念教学。小学数学概念的教学可以从三个维度去进行构建:首先让学生认同该概念产生的价值,在此基础上明晰概念的数学表达形式,深刻把握概念的本质特征,以最有效的方式引发学生的数学思考,提升学生的数学
Mathematical concept is a form of thinking that reflects the essential attributes and characteristics of a mathematical object. A mathematical concept is a form of thinking that reflects the essential attributes and characteristics of a mathematical object and constitutes the basic element of mathematics. Therefore, the concept of teaching is the core teaching of mathematics classroom teaching is the core of mathematics classroom teaching. This article takes “cognition ratio ” teaching as an example to talk about how to carry on concept teaching effectively. The teaching of elementary mathematics concepts can be constructed in three dimensions: firstly, letting students recognize the value of the concept; on the basis of this, clarifying the mathematical expressions of concepts; deeply grasping the essential characteristics of concepts; and provoking students in the most effective way Mathematical thinking, improve students’ math
