提高小学生解答应用题的能力,实现应用题的多能性目标,教师必须以思维训练为主弦律,弹好数学应用题教学五部曲。一、审题由于应用题叙述的生活化语言与数学语言的差别,加上冗长、抽象的特点,学生对理解题意往往产生困难。对此,可采用“缩写”、“改写”的方法帮助理解。“缩写”即是把与解题有关的已知量与未知量从题中分化出来,“去粗取精”、“去伪存真”、重新构建,使句式简单,数量关系趋于明朗“;改写”即把应用题的生活化叙述改
Improve the ability of primary school students to answer the application questions, to achieve the goal of multiplying the application of the problem, teachers must thinking training as the main rhythm, playing a good teaching of mathematics teaching five parts. First, the exam As the application of narrative life language and mathematical language differences, coupled with lengthy, abstract features, students often have difficulty understanding the meaning. In this regard, can be used “abbreviation ”, “rewrite ” method to help understand. “Abbreviation ” is to distinguish the known and unknowns related to the problem from the title, “to faint ”, “to pseudo-true”, rebuild, so that the sentence is simple, the number of relations tends to be clear “; Rewrite ” that is, the application of life narrative change
