20以内加减法口诀表
一、20以内加法口诀表:
20以内的进位加法归纳下来口诀是:
“加九减一,加八减二,加七减三,加六减四,加五减五。
以“加九减一”为例,“加九减一”是指一个数与9相加,将这个数减去1作为它们和的个位。
例如:8+9=()就拿8减去1结果7,用7来作和的个位,即8+9=17,6+9=()就拿6减去1等于5,用5来作和的个位,即6+9=15。
“加八减二,加七减三,加六减四,加五减五”的方法同上。
二、20以内减法口诀表:
20以内退位减法与20以内进位加法相反,就是把20以内退位减法转化为10以内加法。
口诀是:“减九加一,减八加二,减七加三,减六加四,减五加五。
以“减九加一”为例,“减九加一”是指一个数减去9,将这个数的个位加上1所得的结果就是它们的差。
例如:18-9=()就拿18的个位8加上1结果是9,即18-9=9,14-9=()就拿14的个位4加上1结果是5,即14-9=5
“减八加二,减七加三,减六加四,减五加五”与“减九加一”的方法一样。

数学一年级知识点:20以内加减法口诀+练习题
【导语】美国的⼀位数学家说过:学习数学的的⽅法就是“做数学”。
所谓实践就是要完成相当的练习,我们知道我国的数学家陈景润对歌德巴赫猜想取得了突破性的成就,震惊了世界,可他⽤去的草稿纸就有⼏⿇袋!可见做题是多么的重要。
以下是整理的相关资料,希望各位同学有所收获。

进位加法儿歌:退位减法儿歌:
进位加法我会算,数位对齐才能加。
退位减法并不难,数位对齐才能减。
个位对齐个位加,满十要向十位进。
个位数小不够减,要向十位借个一。
十位相加再加一,得数算得快又准。
十位退一是一十,退了以后少个一。
十位数字怎么减,十位退一再去减。
