一年级应用题的教学是小学数学应用题教学的基石;启蒙的好坏,基石的牢固与否,关系到以后应用题教学质量的高低。五年制小学数学课本第一册一、二单元,即10以内的数的认识和加减法、11-20各数的认识;在应用题教学方面,只出现用图画表示的应用题,这是学习应用题的第一个阶梯,它是学习应用题的启蒙阶段。在这一阶段主要是教会学生看图说意,从感性上认识应用题的实际意义。教学中要将课本中的插图(或适当补充)利用实物、模型、幻灯等形式进行形象化演示,把图中的数量关系用形象生动的语言表述出来,训练学生围绕应用题的结构进行说话。如:教认数1时,教会
The application of the first grade teaching is the cornerstone of the teaching of primary school mathematics problems; enlightenment is good or bad, the cornerstone of the firm or not, relates to the quality of the next application of teaching quality. Five-year primary school mathematics textbook first book one or two units, that is, the number of less than 10 understanding and addition and subtraction law, 11-20 understanding of each number; in the teaching of application problems, only the use of pictures that appear in the application, which Is the first step in learning application problems, it is the Enlightenment phase of learning application problems. At this stage, it is mainly to teach the students to look at the pictures and understand the practical significance of the application questions from the perspective of emotion. In the teaching, the illustration (or proper supplement) in the textbook should be visualized in the form of in-kind, model, slideshow and so on, and the quantitative relationship between the figures should be expressed vividly in the vivid language so as to train the students to speak around the structure of the application question. Such as: teaching number 1, the church
