概念是客观事物的本质属性、特征在人们头脑中的反映。数学概念是反映现实世界的空间形式和数量关系的本质属性的思维形式。在小学数学教学中,加强概念的教学,正确理解数学概念是掌握数学基础知识的前提,是学好定理、公式、法则和数学思想的基础,搞清概念是提高解题能力的关键。特别是比较抽象概念的教与学,是数学的一大难点,也是体现集合思想、数形结合思想的代表。
The concept is the essential attribute of objective things, the reflection of the characteristics in people’s minds. Mathematical concepts are the forms of thinking that reflect the essential attributes of the spatial form and quantitative relations in the real world. In elementary mathematics teaching, to strengthen the teaching of concept and correctly understand the concept of mathematics are the prerequisites of grasping the basic knowledge of mathematics, and the basis of learning theorems, formulas, laws and mathematical ideas. Understanding the concept is the key to improving the ability of solving problems. Teaching and learning, especially abstract concepts, is a major difficulty in mathematics and also represents the idea of combining thought and figure with thought.
