在小学低年级数学教学中,要激发刚入学儿童的求知欲,使他们通过积极思维来主动获取知识,教师就有必要精心设计难易适度、富有思考价值的启发性问题,并掌握好课堂提问的时机。何为课堂提问的时机呢?我通常抓住以下三个方面: 一是教学的关键处。如教“求一个数的几倍是多少”的应用题。教学的关键是让学生理解“倍”的含义。这个问题解决了,其它问题也会迎刃而解。于是,我先按教材的图示,将剪好的白蝴蝶和花蝴蝶贴在黑板上,然后问:“花蝴蝶每份的只数跟白蝴蝶的只数有什么关系?”学生看到花蝴蝶每份的只数跟白 In the lower primary school mathematics teaching, to stimulate the curiosity of new-enrolled children, so that they take the initiative to gain knowledge through positive thinking, teachers need to elaborate on the difficulty of moderate and thoughtful enlightenment, and master the classroom questions The timing. What is the timing of the class questions? I usually grasp the following three aspects: First, the key to teaching. Such as teaching “seeking a few times what is the number of” application questions. The key to teaching is to make students understand the meaning of “times.” This problem is solved, other problems will be solved. So, I first press the icon of the textbook, the cut white butterfly and flower butterfly on the blackboard, and then asked: “The number of each butterfly flower butterfly has nothing to do with the number?” Students see the flowers The number of butterflies with each white
