22 － 7 ＝ 15（只）
从22只船里去掉划走的7只，就是剩下的。
看这图道你题解知怎答道样正了解确什答吗么？？？
1、你学到了什么？ 2、你想夸夸谁？向谁学习？为什么？
退位减法
第先说观二说察组7出6这都十－两算么要算的发从。现十？位上退1，是退位减法。
1. 想一想，算一算。
30－6＝24
20 10 4
这道题计算时也是个位不够减，也是退位减法。
0减6不够减，把30分成20和10，先算10－6＝4，再算20＋4＝24。
100以内的加法和减法（一）
两位数减一位数（退位）（1）
口算。 57－4＝53
75－3＝72 69－5＝64
57－40＝17 75－30＝45 69－50＝19
先都算是57把0－相－4同4＝0数3＝，位10上，再的算数15直0接＋相73＝减15。73。
这两说道说题57计－算40你时你是有是什么怎相样同计的算地的方。？

一年级数学下册两位数减一位数(退位)一课一练人教版

（人教版）一年级数学下册两位数减一位数（退位）一、填空。

二、找出得数是36的算式，在算式下面画横线。

27＋9＝ 45－8＝ 34＋2＝51－5＝96－60＝66－30＝28－9＝ 34＋5＝8＋38＝ 44＋8＝ 37＋6＝ 8＋35＝三、先把有关的条件和问题用线连起来，再计算。

（1）（2）（3）四、先说出缺少的条件，再算出来。

（1）鱼缸里有红16条，___________________，红和黑一共有多少条？（2）学校原来有56盒粉笔，___________________，现在有多少盒？（3）停车场有9辆，___________________，一共有多少辆大卡车？（4）草原上有21匹，_____________，比少几匹？五、下面的应用题编得对吗？对的在括号内打√，错的打×。

（1）用 15＋7编一道应用题。

小红做了15朵红花，7朵黄花。

现在做了多少朵花？（）（2）用“30－9”编一道应用题。
