赞可夫曾说:“教会学生思考,这对学生来说,是一生中最有价值的本钱。”作为一名教师,不仅要教授学生知识,更要教会学生思考,使学习的知识“活”起来。还记得去年镇里举行课堂擂台赛时我执教的“3的倍数特征练习”一课。课伊始,我出示练习题:用3的倍数的特征判断,452能被3整除吗?为什么?学生平静地答道:“452不能被3整除,因为4+5+2=11,各数位上数字之和是11,11不是3的倍数,所以这个数不能被3整除。”看
Zakhoof once said: “Teaching students to think, this is the most valuable cost of life for students.” “As a teacher, not only to teach students knowledge, but also to teach students to think, so that learning knowledge ”Alive “ up.

At the beginning of the class, I showed the exercise: Judging by the characteristics of multiples of 3, can 452 be divisible by 3? Why? Students calmly replied: ”452 can not be divisible by 3 because 4 + 5 + 2 = 11, The sum of the numbers is 11, 11 is not a multiple of 3, so this number can not be divisible by 3. "Look
