一、动手操作易于理解数学概念 由于数学知识的抽象性与小学生思维的形象性的矛盾,教学中必须根据学生的年龄特点,把有关的概念寓于他们日常生活所能接触的事物之中,赋予它丰富的内容与形式,设计一系列的操作活动。如教“3”的认识,可以让学生观察主题画,数一数图上有几个工人,几台彩电等,突出这些东西的数量都是“3”可以用数字“3”来表示,从而初步抽象概括出“3”的基本含
First, the hands-on operation easy to understand the concept of mathematics Due to the mathematical knowledge of the abstract and primary thinking of the image of the contradictions in the teaching must be based on the characteristics of the students of the age, the concept of the concept of their daily life can be touched by things, given it Rich content and form, design a series of operational activities. Such as teaching “3” awareness, allowing students to observe the theme of the painting, the number one figure on the number of workers, several color TV sets, etc., highlighting the number of these things are “3” can be used to indicate the number “3” The initial abstraction summarizes the “3” basic contains
