数学源于生活,现实生活就在数学课堂上。面对枯燥的笔算加、减、乘、除法的教学方法,我们更加清楚地认识到,把教材内容情境化,设计出现实的、有趣的、富有挑战性的问题情境,容易激活学生已有的生活经验和数学知识,从而将静态的、抽象的知识变得动态化和形象化了,让学生不由自主地产生问题,直至激活思维,迅速解决问题,完成再创造过程。一、创设生活情境新教材的呈现方式是丰富多彩的,采用多种多样 Mathematics comes from life, real life in mathematics classroom. In the face of boring teaching methods of counting, subtracting, multiplying and dividing, we recognize more clearly that it is easy to activate the existing situation of students by deconstructing the contents of the teaching materials and designing realistic, interesting and challenging problem situations Life experience and mathematical knowledge, so that the static, abstract knowledge become dynamic and visualization, so that students can not help but produce problems until the activation of thinking, quickly solve the problem, to complete the process of re-creation. First, the creation of life situations The new textbook presentation is rich and varied, using a wide range of
