一年级下6.1《整十数加减整十数》《一年级下 61《整十数加减整十数》》对于一年级的小朋友们来说，数学的世界就像一个充满奇妙和惊喜的乐园。

在这个乐园里，“整十数加减整十数”可是一个非常重要的知识关卡哦！那什么是整十数呢？像 10 、 20 、 30 、 40 、 50 、 60 、 70 、 80 、90 这样个位上是 0 的数，就是整十数。

那整十数的加减法又该怎么算呢？别着急，咱们一起来看看。

比如说，有 30 个苹果，又拿来了 20 个苹果，那现在一共有多少个苹果呢？这就是一个整十数相加的问题。

30 加上 20 ，我们可以这样想：3 个十加上 2 个十，就是 5 个十，5 个十就是 50 。

所以 30 ＋ 20 ＝ 50 。

再比如，有 50 个气球，飞走了 20 个，还剩下多少个气球呢？这就是整十数相减。

50 减去 20 ，我们可以想：5 个十减去 2 个十，还剩下3 个十，3 个十就是 30 ，所以 50 20 ＝ 30 。

为了让小朋友们更好地理解整十数的加减法，老师和家长可以准备一些直观的教具，比如小棒、计数器等等。

咱们先用小棒来演示。

比如计算 40 ＋ 30 ，可以先拿出 4 捆小棒表示 40 ，再拿出 3 捆小棒表示 30 ，把它们合在一起，数一数一共有 7捆小棒，也就是 70 。

再用计数器来看看。

还是算 40 ＋ 30 ，在计数器的十位上拨 4 个珠子表示 40 ，再在十位上拨 3 个珠子表示 30 ，这时十位上一共有 7 个珠子，就表示 70 。

小朋友们在做整十数加减法的时候，要注意先看清楚数字，想清楚是几个十加上或减去几个十，这样就能算得又快又准啦。

那咱们来做几道练习题巩固一下吧。

20 ＋ 50 ＝（） 70 30 ＝（） 60 ＋ 30 ＝（） 90 40 ＝（）小朋友们，做完这些题目，是不是觉得整十数的加减法也没有那么难呀？在日常生活中，整十数的加减法也有很多用处呢。

比如去超市买东西，一包薯片 10 元，买 3 包就是 30 元；妈妈买了 60 个鸡蛋，吃了 20 个，还剩下 40 个。

一年级整十数加整十数的题
一、知识点讲解
1. 定义
整十数是指个位为0的两位数，如10、20、30等。

整十数加整十数就是将几个十与几个十相加。

2. 计算方法
计算整十数加整十数时，可以把整十数看成几个十，然后直接相加。

例如，20+30，20就是2个十，30就是3个十，2个十加3个十等于5个十，也就是50。

也可以根据数的组成，十位上的数字相加，个位写0。

如30 + 40，3+4 = 7，结果就是70。

二、题目示例及解析
1. 题目
10+20 =
解析：把10看作1个十，20看作2个十，1个十加2个十等于3个十，所以10+20 = 30。

2. 题目
30+40 =
解析：30是3个十，40是4个十，3个十加4个十等于7个十，即70，也可以直接计算3 + 4 = 7，然后在结果后面添0，得到70。

3. 题目
50+20 =
解析：5个十加2个十等于7个十，所以50+20 = 70。

4. 题目
40+30 =
解析：4个十加3个十等于7个十，结果是70。

5. 题目
60+10 =
解析：6个十加1个十等于7个十，答案为70。

6. 题目
20+70 =
解析：2个十加7个十等于9个十，即90。
