教学倍数应用题时帮助学生掌握正确的分析数f关系的方法非常重要。教师在教学中要在正确分析题中的数A关系的基础上,加深学生对“倍”的应用题的内在联系的认识,这是教给学生分析“倍”的应用题的方法的关键所在。一、学生掌握分析理解“倍”的应用题的结构的方法(一)扎实的建立“倍”的概念基础1.理解“倍”的意义在解决“倍”的应用题结构的认识时,重点应抓住应用题的数量关系。让学生从易到难地认真分析理解。“倍”的概念是学习有关“倍”的三类应用题的基础,只有学生熟练正确的理解“倍”的概念,才能运用它去分析问题并解答有关的应用题,进而形成技能与能力。
Teaching multiple application questions to help students master the correct number of analysis f relationship is very important. Teachers in teaching correctly analyze the relationship between the number of A on the basis of deepening students “times ” application of the problem of the inherent linkages, which is to teach students to analyze “times ” application The key to the method. First, the students master the method of understanding the structure of the application of “times” (a) a solid foundation of the concept of “times” 1. Understand the meaning of “times” in the solution of “times” When applying the problem structure understanding, the emphasis should be on the quantitative relationship of the applied questions. Students from easy to difficult to carefully analyze the understanding. The concept of “times ” is to learn the basis of the three types of application questions about “times ”, only students proficiency in the correct understanding of “times ” concept, to use it to analyze the problem and answer the relevant application questions, Thus forming skills and abilities.
