归纳猜想型试题是给出一定条件(可以是有规律的算式、图形或图表),让同学们认真分析,仔细观察、归纳,发现共同特征,大胆猜想,据此去预测它的变化规律,并能够应用此结论。在近几年各地中考数学试卷中,此类题型逐步成为热点内容之一。解归纳猜想型试题的具体方法和步骤是:(1)通过对几个特例的分析,寻找规律并且归纳;(2)猜想符合规律的一般性结论;(3)验证或说明结论是否正确。下面举例说明。
The conjecture conjecture questions are given certain conditions (which can be regular arithmetic, graph or chart), let the students carefully analyze, carefully observe, summarize, find common features, bold conjecture, accordingly to predict its variation, and Can apply this conclusion. In recent years around the math test papers, such questions gradually become one of the hot topics. The specific methods and steps to solve the conjecture conjecture are as follows: (1) Through the analysis of several special cases, we can find the law and summarize it; (2) We can guess the general conclusion that accord with the law; (3) Verify or prove the conclusion is correct. Here’s an example.
