陶行知曾说:“发明千千万,起点在一问。”科学史上每一项重大发现都是从问题开始的:牛顿发现万有引力是从“苹果为什么落地”这一问题开始的;弗莱明发现青霉素是从“为什么霉菌菌落周围没有细菌”开始的。心理学研究表明:学生思维活动是从问题开始,并在解决问题中得到发展的。所以,在小学数学教学中,我们要认真贯彻《数学课程 Tao Xingzhi once said: “The invention of tens of millions starts at 1.” Every major discovery in the history of science begins with the question: Newton discovers that gravitation begins with the question “Why did Apple land?” ; Fleming found that penicillin started from “why there are no bacteria around the mold colonies.” Psychological research shows that: student thinking activities from the beginning of the problem, and to solve problems in the development. Therefore, in elementary mathematics teaching, we must conscientiously implement the "mathematics curriculum
