一年级上册口算50题

一年级上册口算50题一年级上册口算练习题(人教版)一、不带进位加法(1 - 10)1. 题目:1 + 2 =。

- 解析:这是最基础的加法运算,1表示1个物体,2表示2个物体,把它们合在一起就是3个物体,所以1+2 = 3。

2. 题目:3+4 =。

- 解析:3个物品加上4个物品,我们可以通过数手指或者在脑海中想象物品的数量来计算,先数出3个,再接着数4个,得到7个,即3 + 4 = 7。

3. 题目:2+5 =。

- 解析:2加上5,我们可以从2开始往后数5个数,2、3、4、5、6、7,所以2+5 = 7。

4. 题目:1+3 =。

- 解析:1和3相加,1个加上3个,一共是4个,答案是1+3 = 4。

5. 题目:4+2 =。

- 解析:4个再加上2个,就像我们有4个小方块,又拿来2个小方块,数一数就知道一共有6个小方块,所以4+2 = 6。

二、带进位加法(1 - 10)1. 题目:5+6 =。

- 解析:先把5记在心里,然后接着数6个数,6、7、8、9、10、11,所以5+6 = 11。

也可以想5和5凑成10,6比5多1,10再加1就是11。

2. 题目:7+4 =。

- 解析:可以把4分成3和1,7先加上3等于10,10再加上1就是11,所以7+4 = 11。

3. 题目:8+3 =。

- 解析:8和2凑成10,3可以分成2和1,8加2得10,10再加1就是11,所以8+3 = 11。

4. 题目:9+2 =。

- 解析:9再往后数2个数就是11,所以9+2 = 11。

也可以想9离10差1,2可以分成1和1,9加1得10,10再加1就是11。

三、不带退位减法(1 - 10)1. 题目:5 - 2 =。

- 解析:5个东西拿走2个,还剩下3个,所以5 - 2 = 3。

2. 题目:7 - 3 =。

- 解析:7个物体减去3个物体,就剩下4个物体,即7 - 3 = 4。

3. 题目:8 - 5 =。

- 解析:8里面去掉5,我们可以数8个手指,弯下5个,还剩下3个手指是伸直的,所以8 - 5 = 3。
