小学四年级数学口算加减法教案教学目标

1.能正确的口算整百整十数加、减整百整十数、以及整万数的加减法.

2.培养学生推理能力.

教学重点

掌握口算方法.

教学难点

培养学生计算的正确性.

教学过程

一、复习导入

口算,并说一说口算过程

27+38=64-38=250+70=530-300=250+400=二、学习新课

(一)教师谈话:我们已经学习了两位数加、减两位数,两位数加、减整十、整百的口算,今天我们继续学习口算加、减法.(板书课题:口算加、减法)今天学习的口算加、减法与过去的有什么不同呢?

教师把最后一道口算题250+400改为250+470(即例1)1.提问:同学们会口算250+400,那么怎样口算250+470呢?请大家试一试.

2.学生交流汇报,并说说自己是怎样想的?(演示课件口

算加、减法)

板书汇报结果.(设想三种方法)

A.200+400=600,50+70=120,600+120=720

B.250+400=650,650+70=720

C.25+47=72,250+470=720

(第三种方法是把250看作25个十,470看作47个十,25个十加47个十得72个十,所以250+470=720)学生说出这种方法应给予鼓励.

(二)教学例2

1.出示例2 口算:540-370

2.小组讨论:怎样口算才能又对又快.

3.汇报结果,说出思路.

540-370=170

A.540-300=240,240-70=170

B.540-340=200,200-30=170

C.540-70=470,470-300=170

D.54-37=17,540-370=170

教师肯定这四种方法正确,同时说明第四种方法:把540看作54个十,370看作37个十,54个十减37个十得17个十,所以540-370=170

4.练习

(1)口算(要求说出口算过程,方法自选)

360+180 410-240 520-150 370+58

(2)一个数是390,另一个数比它多150,另一个数是多少?(三)教学例3

1.出示例3、口算:

(1)17万+8万=_________万

由学生自己说思路

(2)27万+19万=_________万

因为27+19=46, 所以27万+19万=46万

(3)27万-4万=_________万

因为27-4=23, 所以27万-4万=23万

(4)35万-28万=_________万

因为35-28=7, 所以35万-28万=7万

2.练习

(1)口算(要求说出口算过程)

34万+18万=23万-18万=

250万+750万=50万-27万=

(2)一个数是820万,另一个数比它少150万,这个数是多少?

三、课堂练习

69万+26万82万-54万230万-70万

四、课堂小结

这节课我们都学习了什么知识?你是怎么口算的?(让学生各抒己见,讲出自己采用的方法)

五、课后作业

1.口算下面各题.

320+60=350+460=330-80=

250+490=270+28=760-450=

520+480=670-500=400-260=

2.口算下面各题.

170+320=100-51=630+27=

850-40=650+180=860-47=

“师”之概念,大体是从先秦时期的“师长、师傅、先生”而来。其中“师傅”更早则意指春秋时国君的老师。《说文解字》中有注曰:“师教人以道者之称也”。“师”之含义,现在泛指从事教育工作或是传授知识技术也或是某方面有特长值得学习者。“老师”的原意并非由“老”而形容“师”。“老”在旧语义中也是一种尊称,隐喻年长且学识渊博者。“老”“师”连用最初见于《史记》,有“荀卿最为老师”之说法。慢慢“老师”之说也不再有年龄的限制,老少皆可适用。只是司马迁笔下的“老师”当然不是今日意义上的“教师”,其只是“老”和“师”的复合构词,所表达的含义多指对知识渊博者的一种尊称,虽能从其身上学以“道”,但其不一定是知识的传播者。今天看来,“教师”的必要条件不光是拥有知识,更重于传播知识。

宋以后,京师所设小学馆和武学堂中的教师称谓皆称之为“教谕”。至元明清之县学一律循之不变。明朝入选翰林院的进士之师称“教习”。到清末,学堂兴起,各科教师仍沿用“教习”一称。其实“教谕”在明清时还有学官一意,即主管县一级的

教育生员。而相应府和州掌管教育生员者则谓“教授”和“学正”。“教授”“学正”和“教谕”的副手一律称“训导”。于民间,特别是汉代以后,对于在“校”或“学”中传授经学者也称为“经师”。在一些特定的讲学场合,比如书院、皇室,也称教师为“院长、西席、讲席”等。240+56=520-360=910-180=

要练说,得练听。听是说的前提,听得准确,才有条件正确模仿,才能不断地掌握高一级水平的语言。我在教学中,注意听说结合,训练幼儿听的能力,课堂上,我特别重视教师的语言,我对幼儿说话,注意声音清楚,高低起伏,抑扬有致,富有吸引力,这样能引起幼儿的注意。当我发现有的幼儿不专心听别人发言时,就随时表扬那些静听的幼儿,或是让他重复别人说过的内容,抓住教育时机,要求他们专心听,用心记。平时我还通过各种趣味活动,培养幼儿边听边记,边听边想,边听边说的能力,如听词对词,听词句说意思,听句子辩正误,听故事讲述故事,听谜语猜谜底,听智力故事,动脑筋,出主意,听儿歌上句,接儿歌下句等,这样幼儿学得生动活泼,轻松愉快,既训练了听的能力,强化了记忆,又发展了思维,为说打下了基础。
