解答数学题,有时需要把条件、问题以及它们之间的数量关系用图形或表格的形式表示出来,借助直观的图表分析、推理,寻求解题途径。这种方法叫做图表法。 “数形结合”本来就是一种重要的数学思想方法。和语言、文字比,图表形象、直观,特别适合于以形象思维为主的小学生。 一、示意图 小学生的语言、文字的识别能力不足,对 To solve math problems, sometimes it is necessary to express the conditions, problems and the quantitative relations between them in the form of graphs or tables. With the help of intuitive chart analysis and reasoning, we can find solutions to problems. This method is called charting. The “combination of numbers and shapes” has always been an important mathematical method. And language, text ratio, the image of the chart, intuitive, especially suitable for image-based primary school students. First, the schematic pupil language, text recognition capacity is insufficient, right
