小学数学教学的主要任务之一是使学生掌握一定的数学基础知识。而概念是数学基础知识中最基础的知识,是学生计算能力提高,空间观念形成,思维能力发展的前提和重要保证。因此数学概念的教学是数学教学的核心。一、引入,认识概念的前提概念教学的第一步就是引入概念,概念如何引入,将直接关系到学生对概念的理解和掌握。概念引入得当,能激发学生的学习兴趣及探究欲望,把学习新知的压力变为探求新知的动力。(一)实践操作引入
Primary mathematics teaching one of the main tasks is to enable students to master a certain basic knowledge of mathematics. However, the concept is the most basic knowledge in the basic knowledge of mathematics, which is the prerequisite and important guarantee for the students to improve their computational ability, form the concept of space and develop the thinking ability. Therefore, the teaching of mathematical concepts is the core of mathematics teaching. First, the introduction of the premise of the concept of understanding the concept of teaching the first step is to introduce the concept of how to introduce the concept will be directly related to the student’s understanding and mastery of the concept. Proper introduction of concepts can stimulate students’ interest in learning and explore the desire to change the pressure of learning new knowledge into the motivation to explore new knowledge. (A) the introduction of practical operation
