空间与图形的教学是小学数学教学的重要组成部分之一,其知识来源于现实世界,但往住又是现实世界的抽象,因而看似具体,实则很抽象。小学生空间观念比较弱,解决几何问题有时很难理解。本文从实践操作,体验知识的形成、举一反三,触类旁通促理解两个方面来阐述如何在小学数学课堂教学中,引导学生理解空间与图形,以更好地培养学生的空间观念,提高小学数学课堂教学效果。
The teaching of space and graphics is one of the most important parts of mathematics teaching in primary schools. Its knowledge comes from the real world. However, the past and present are abstractions in the real world. Therefore, it seems concrete and abstracts in reality. Pupils space concept is relatively weak, to solve the geometric problems are sometimes difficult to understand. This article explains how to guide students to understand space and graphics in mathematics classroom teaching in order to better cultivate students’ space concepts and improve the teaching of mathematics in primary schools from two aspects: practical operation, experience knowledge formation, effect.
