20以内连加连减口算题

20以内连加连减口算题一、连加口算题1. 题目- 2 + 3+ 4- 1+2 + 5- 3+4+2- 4 + 5+12. 解析- 对于2 + 3+ 4:- 先计算2+3 = 5,这是根据数的组成,2和3合起来是5。
- 再计算5+4 = 9,同样是数的组成,5和4合起来是9。
- 对于1+2 + 5:- 先算1+2 = 3,1个一加上2个一是3个一。
- 然后算3+5 = 8,3个一加上5个一是8个一。
- 对于3+4+2:- 先得出3 + 4=7,因为3和4组成7。
- 再算7+2 = 9,7个一加上2个一是9个一。
- 对于4 + 5+1:- 先计算4+5 = 9,4个一和5个一合起来是9个一。
- 再算9+1 = 10,9个一加上1个一是10个一,也就是10。
二、连减口算题1. 题目- 9 - 2- 3- 8-3 - 1- 10 - 4-2- 7-2 - 32. 解析- 对于9 - 2- 3:- 先算9 - 2=7,9个一去掉2个一还剩7个一。
- 再算7-3 = 4,7个一去掉3个一还剩4个一。
- 对于8-3 - 1:- 先计算8 - 3=5,8个一去掉3个一剩下5个一。
- 再算5-1 = 4,5个一去掉1个一剩下4个一。
- 对于10 - 4-2:- 先得出10 - 4 = 6,10个一去掉4个一还剩6个一。
- 再算6-2 = 4,6个一去掉2个一还剩4个一。
- 对于7-2 - 3:- 先算7-2 = 5,7个一去掉2个一剩下5个一。
- 再算5-3 = 2,5个一去掉3个一剩下2个一。

一年级20以内连加连减口算练习题

一年级20以内连加连减口算练习题对于一年级的小朋友来说,掌握 20 以内的连加连减口算能力是数学学习中非常重要的一环。
为了帮助小朋友们更好地练习和提高这一能力,以下为大家准备了一系列的练习题。
首先,让我们来了解一下什么是 20 以内的连加连减。
连加就是把三个或三个以上的数相加,例如 2 + 3 + 5 = 10 ;连减则是从一个数中连续减去两个或两个以上的数,比如 15 3 2 = 10 。
为了让小朋友们熟悉这种计算方式,我们来做几道简单的练习题。
第一组:1、 3 + 2 + 5 =2、 1 + 4 + 6 =3、 2 + 1 + 7 =4、 4 + 3 + 2 =5、 5 + 1 + 3 =这一组练习题主要是让小朋友们先感受一下连加的运算,数字都比较小,容易计算。
接下来是第二组:1、 7 + 3 + 1 =3、 5 + 4 + 2 =4、 9 2 3 =5、 6 + 3 1 =这一组的题目稍微增加了一点难度,既有连加,又有连减。
然后是第三组:1、 4 + 5 + 3 =2、 10 4 2 =3、 3 + 6 + 4 =4、 8 3 2 =5、 7 + 2 + 1 =这一组的数字会更大一些,需要小朋友们更加认真地计算。
再来看第四组:1、 5 + 7 3 =2、 9 + 1 5 =3、 6 + 5 2 =4、 12 3 4 =这一组的题目难度又有所提升,需要小朋友们更加细心。
最后是第五组:1、 7 + 5 4 =2、 11 2 3 =3、 4 + 8 2 =4、 10 5 3 =5、 6 + 6 5 =做完这些练习题之后,小朋友们可以自己检查一下答案,看看自己做对了多少。
如果做错了,也不要灰心,多练习几次就会越来越熟练的。
在做 20 以内连加连减口算练习题的时候,小朋友们可以先从左到右依次计算,先算出前面两个数的结果,再和第三个数进行计算。
比如 3 + 5 + 2 ,先算 3 + 5 = 8 ,再算 8 + 2 = 10 。
