小学数学涉及的各类典型应用题,尽管其结构、形式和数量关系有所不同,但在解题方法上却有着密切的联系。弄清它们之间的联系,就不会孤立地看待各类应用题和死记硬背公式,从而提高解答应用题的能力。下面以“归一问题”为主线,谈谈教材中各类应用题之间的关系。 Although all kinds of typical application topics involved in elementary mathematics are different in structure, form and quantity, they are closely related to the method of problem solving. To find out the relationship between them, you will not look at all kinds of application problems and rote formulas in isolation, thus improving the ability to answer the questions. The following to “normalize the problem” as the main line, talk about the relationship between the various types of application questions in the textbook.
