在一年级的数学教学中,20以内进位加法和退位减法既是教学的重点,又是教学的难点。

一般的孩子在学前班时就学会了10以内加减法,进入小学后,20以内不进位不退位的加减法稍加练习也能熟练掌握。

但是,孩子学习进位加法和退位减法就不是那么轻松了,部分学生的计算速度大大下滑,计算的准确率也降低了,两极分化初露端倪。

有的学生由于计算速度跟不上,开始拖拉作业,成为数学学习困难者。

那么,到底是什么原因造成了孩子学习20以内进位加法以及退位减法的困难呢?我认为,这和我们运用的计算进位加法和退位减法的算法有关。

算法不外乎数数法和数字推理法,数数法就是通过数数来计算,包括借助实物数数和单纯数数两种。

数字推理法指的是包含凑十法、拆分法等的运用数字进行推算的方法。

然而,数字推理法对学生的思维要求高,需要的思维步骤也多,并不利于学生熟练掌握最终到达到脱口而出的地步。

以运用最为广泛的凑十法为例,求9加6等于几,学生在解决问题之前就需要这几个思考过程:
一.判定该题是不是进位加法;二、如果是进位加法,怎样才能凑成10。

这样确定方法后才能进行下面的运算:9+6=9+(1+5)=(9+1)+5=10+5=15 从上面的运算中可以看出,这是一个运用加法结合律进行简便计算的一个过程,而且属于不能直接运用题中数据,需要拆分才能进行简便运算的一类。

所以,看似简单的凑十法,其思维是不简单的,包含着一系列逻辑推理过程,它的认知基础与一年级学生所具有的知识结构和思维能力之间存在一定的距离,一定程度上造成了学生计算的困难。

那么,怎样的方法才能更好地解决这一难题呢?我是这样做的: 20以内进位加法:怎样才能使学生能在较短时间内掌握20以内进位加法,只要将其转化为学生已经掌握的10以内减法就行了,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。

”怎样用口诀,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, 5+9=()就拿5减去1等于4,用4来作和的个位,即5+9=14“加八减二,加七减三,加六减四,加五减五”的方法同上。

20以内退位减法: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。

”如何用口诀,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:17-9=()就拿17的个位7加上1结果是8,即17-9=8,13-9=()就拿13的个位3加上1结果是4,即13-9=4“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。

一年级学生还不能正确的行抽象思维,采用以上方法,能使习惯依赖摆实物来计算的学生脱离实物也能快速准确的算出结果,避免了死记硬背,盲目多练,提高了运算速度,降低了出错率,减轻了学生的学习负担。
