带小括号的加减法

带小括号的加减法
带小括号的加减法

第六课时小括号

教学目标

1、认识小括号,初步了解带小括号的加、减两步式题的运算顺序。

2、正确计算带小括号的加、减两步式题。

3、能准确判断两步式题的运算顺序。

4、能准确地计算带小括号的加、减两步式题。

教学重点

使学生认识小括号及其作用。

教具、学具准备

投影片、口算卡。

教学过程

(一)铺垫孕伏

1、直接说得数。

15-6= 17-8= 5+4= 8+4=

5+6= 11-4=

2。说说14-8-3、8+6-7、15-7+5的计算顺序。

(二)探究新知

1、导入

引导学生回忆加、减两步式题的运算顺序是从左到右依次计算。今天我们继续学习加、减两步式题。

2、教学例2。

⑴出示糖果投影图:

从图上看到了什么?

⑵同学们拿出圆片,代表五角星,在桌上摆一摆。

想一想:怎样算出还剩几个呢?如何列算式呢?相互之间可以讨论一下。

⑶引导学生说出不同的解题思路:

①从10个里面去掉2个,再去掉3个,剩下5个。

②把2个和3个合起来一共是5个,再从10个里面一起去掉5个,

还剩5个。

③样列算式呢?板书:“10-2-3=”“10-(2+3)=”

第一种算法:先算10减2,再减3。

第二种算法:计算中要先计算2+3,但这一步在后面,这就需要改变运算顺序,因此要在先计算的这一步加上一个小括号。板书课题:“小括号”

师生共同根据小括号的作用,列出两种算法的算式。

10-2-3= 10-(2+3)=

④引导学生计算。

10-2-3=先算10-2=8,再算8-3=5。(板书结果)

10-(2+3)=先算2+3=5,再算10-5=5。(板书结果)

(三)全课小结

今天你学到了什么?

明确:我们学习了带小括号的加减两步式题的计算方法:“在一个算式里有括号的,先算括号里面的。”

教师指出:这个括号与前面的填括号的题不同,如5+()=11是要在括号里填一个数6,而10-(2+3)括号里给出了数和加号,是要先算2+3=5
