教会学生利用实物图、框图、线段图、几何图、韦恩图、统计图等直观地分析应用题,对提高学生解答应用题的能力,是很有帮助的。一、利用框图分析应用题设计一些框图,在每个框图中写上已知的或未知的数量,用箭头把各个框图按照分析过程联起来。并用运算符号、等号表示框图问的关系。例1.一个被服厂计划做上衣1500件,前3天每天做150件,以后提高效 Church students to use the physical map, block diagram, line drawing, geometric figure, Wayne diagram, statistical analysis of intuitive application questions, to improve students' ability to answer questions, is very helpful. First, the use of block diagram analysis Application of some block diagram design, in each block diagram to write the number of known or unknown, with arrows to link the various block diagram in accordance with the analysis process. And use the symbol, the equal sign that the relationship between the block diagram. Example 1. A clothing factory plans to make a shirt 1500, the first three days a day to do 150, after improving efficiency
