联想,即把解决较简单问题所采用的办法、经验和所获得的结论,类推到较繁杂、较陌生的相似情境中,从而迅速地找到解决问题的办法。善于联想,能增强同学们思维的敏捷性.例1不进行计算,比较下面两个数的大小:A=123456789×987654321,B=123456788×987654322.容易看出:123456789+987654321=123456788+987654322,这就使我们联想到这样一道我们都比较熟悉的结论:“如果长方形
Lenovo, that is, the methods, experiences, and conclusions that are used to solve simpler problems are analogized to more complicated and unfamiliar similar situations to quickly find a solution to the problem. Being good at associating can enhance the agility of the students’ thinking. Example 1 does not calculate, compare the size of the following two numbers: A=123456789×987654321, B=123456788×987654322. It is easy to see: 123456789+987654321=123456788+987654322, This reminds us of such a conclusion that we are all more familiar with: "If the rectangle
