一年级20以内加减法口算题1

一年级20以内加减法口算题1一年级20以内加减法口算题。
一年级是学习基础数学知识的关键时期,加减法口算是其中的重要内容。
通过口算练习,可以帮助学生提高计算能力和逻辑思维能力。
下面我们来看一些20以内的加减法口算题。
1. 7 + 3 = 。
2. 15 8 = 。
3. 9 + 6 = 。
4. 12 5 = 。
5. 4 + 9 = 。
6. 18 7 = 。
7. 5 + 5 = 。
8. 11 3 = 。
9. 8 + 4 = 。
10. 17 9 = 。
通过这些简单的口算题,学生可以锻炼加减法的基本技能。
同时,老师可以根据学生的实际情况,适当增加难度,让他们逐步提高计算能力。
在进行口算练习时,老师可以采用多种方式,比如口头快速问答、小组竞赛等,让学生们在愉快的氛围中学习。
此外,老师还可以设计一些趣味性的口算游戏,让学生在游戏中学习,激发他们的学习兴趣。
除了在课堂上进行口算练习,家长们也可以在家里和孩子一起做口算题。
可以利用日常生活中的场景,比如购物、做饭等,让孩子动手算一算,锻炼他们的计算能力。
在进行口算练习时,学生们需要注意一些细节。
比如加法口算时,要注意进位;减法口算时,要注意借位。
同时,还要注意计算过程的正确性,避免出现粗心错误。
通过口算练习,学生不仅可以提高计算能力,还可以培养逻辑思维能力。
口算是一种简单而有效的学习方法,可以帮助学生打好基础,为以后的学习打下坚实的基础。
总之,20以内的加减法口算题是一年级学生必须掌握的基本技能。
通过口算练习,学生可以提高计算能力,培养逻辑思维能力,为以后的学习打下坚实的基础。
希望老师和家长们能够重视口算练习,为学生的数学学习打下良好的基础。
一年级20以内加法计算题可打印

一年级20以内加法计算题可打印一年级20以内加法计算题(人教版)一、题目。
1. 1 + 2 =.解析:1表示1个物体,2表示2个物体,把它们合起来就是3个物体,所以1+2 = 3。
2. 3 + 1 =.解析:3个物体再加上1个物体,一共就是4个物体,所以3 + 1 = 4。
3. 2 + 3 =.解析:先有2个,又加上3个,2、3、4、5,总共是5个,所以2+3 = 5。
4. 4 + 1 =.解析:4个加上1个,就是从4开始往后数1个数,那就是5,所以4 + 1 = 5。
5. 1 + 3 =.解析:1个和3个合起来,数一下就是4个,所以1+3 = 4。
6. 2 + 2 =.解析:2个再加2个,2、4,一共是4个,所以2+2 = 4。
7. 3 + 2 =.解析:3个物体加上2个物体,数一下得到5个物体,所以3+2 = 5。
8. 1 + 4 =.解析:1和4合起来,从1开始往后数4个数,1、2、3、4、5,所以1+4 = 5。
9. 2 + 1 =.解析:2个加上1个,一共就是3个,所以2+1 = 3。
10. 0 + 3 =.解析:0表示没有,加上3个,结果就是3个,所以0+3 = 3。
11. 1 + 1 =.解析:1个加上1个,那就是2个,所以1+1 = 2。
12. 3 + 0 =.解析:3个加上0个(也就是没有增加),还是3个,所以3+0 = 3。
13. 2 + 4 =.解析:2个加上4个,2、3、4、5、6,总共是6个,所以2+4 = 6。
14. 4 + 2 =.解析:4个再加上2个,从4开始往后数2个数,4、5、6,所以4+2 = 6。
15. 1 + 5 =.解析:1个和5个合起来,1、2、3、4、5、6,总共是6个,所以1+5 = 6。
16. 3 + 3 =.解析:3个加上3个,3、4、5、6,一共是6个,所以3+3 = 6。
17. 2 + 5 =.解析:2个加上5个,2、3、4、5、6、7,总共是7个,所以2+5 = 7。

一年级数学20以内训练题

一年级数学20以内训练题一、20以内加法训练题(10题)1. 3 + 5 =.- 解析:3和5合起来是8,所以3+5 = 8。
2. 2+9 =.- 解析:先把2记在心里,再往后数9个数,3、4、5、6、7、8、9、10、11,所以2 + 9=11。
3. 4+7 =.- 解析:4可以分成1和3,先算7+3 = 10,再算10+1 = 11,所以4+7 = 11。
4. 1+12 =.- 解析:12往后数1个数就是13,所以1+12 = 13。
5. 6+9 =.- 解析:6可以分成5和1,先算9 + 1=10,再算10+5 = 15,所以6+9 = 15。
6. 8+7 =.- 解析:8可以分成5和3,7可以分成5和2,先算8+2 = 10,7+3 = 10,再算10+5 = 15,所以8+7 = 15。
7. 5+8 =.- 解析:5可以分成3和2,先算8+2 = 10,再算10+3 = 13,所以5+8 = 13。
8. 3+11 =.- 解析:11往后数3个数,12、13、14,所以3+11 = 14。
9. 7+9 =.- 解析:7可以分成6和1,先算9+1 = 10,再算10+6 = 16,所以7+9 = 16。
10. 2+13 =.- 解析:13往后数2个数,14、15,所以2+13 = 15。
二、20以内减法训练题(10题)1. 15 - 3 =.- 解析:15可以分成10和5,先算5 - 3 = 2,再算10+2 = 12,所以15 - 3 = 12。
2. 11 - 2 =.- 解析:11可以分成10和1,先算1 - 2不够减,从10里面借1个变成10 - 1 = 9,再加上剩下的1就是9+1 = 9,所以11 - 2 = 9。
3. 13 - 4 =.- 解析:13可以分成10和3,先算10 - 4 = 6,再算6+3 = 9,所以13 - 4 = 9。
4. 18 - 9 =.- 解析:18可以分成10和8,先算10 - 9 = 1,再算1+8 = 9,所以18 - 9 = 9。
