笔者最近听了一节第十一册分数应用题的复习题的复习课,有一道复习题,学生的回答出现了错误,老师不批评,也不直接告诉结论,而是抓住契机,培养学生的思维能力。这道复习题是: 果园里有桃树300棵,比梨树少1/4,梨树有多少棵? 学生板演列的算式有两种: (1)300×(1-1/4)=300(棵) (2)300÷(1-1/4)=400(棵) The author recently listened to a review of the eleventh book application questions of the review class review class, there is a review questions, the student's answer appeared wrong, the teacher does not criticize, nor tell the conclusion directly, but seize the opportunity to develop students Thinking ability. This road review questions are: there are 300 peach trees in the orchard, less than a quarter of pear trees, pear tree how many trees? Student board presentation formula has two kinds: (1) 300 × (1-1 / 4) = 300 (tree) (2) 300 ÷ (1-1 / 4) = 400 (tree)
