应用题是小学数学教学的重、难点,许多小学生对应用题感到困难,不知道如何分析其中的数量关系。其实应用题就是结合生活情境设置的数学问题,其中各个数量关系都通过生活情境逻辑串联起来,需要我们通过阅读理解加以辨别。我们只有捋顺数量的逻辑关系,才能通过已知量求得未知量,这样才能掌握数学知识,解决实际问题。下面我们就结合教学实践分析两种引导小学生掌握数学应用题逻辑关系的方法。一、找准比较什么 Application questions are the primary and secondary mathematics teaching heavy and difficult, many of the primary school students find it difficult to apply the question, do not know how to analyze the quantitative relationship among them. In fact, the practical problem is to combine the mathematical settings of life situations, in which the relationship between the number of life through the logic of the series together, we need to be understood by reading comprehension. Only by the logical relation of quantity, can we get the unknown quantity by the known quantity, so as to master the mathematical knowledge and solve the practical problems. Below we combine teaching practice to analyze two kinds of guiding students to master the logical relationship between mathematical applications. First, find out what to compare
