一、复习

1.复习比较两个数的大小。

师:我们已经学了怎样比较亿以内数的大小,谁来说一说比较大小的方法。(指名1、2个学生回答)

师让学生自己完整的.总结:首先要看数位是否相同,相同的数位就要从最高位比起,如果不能比较出来,就一位一位往下比,直到比出大小为止。如果数位不相同,就看哪一个数的数位多那个数就大。

2.复习把整万的数改写成用“万”作单位的数。

1100000=110万 1210000=121万 720000=72万

师:要写成以“万”作单位的数就要把万后面的零去掉,要加上一个“万”字。

3.做一做练习 学生独立完成,全班核对。

二、复习求近似数的方法

1.让学生表演地球与太阳(课本例6)。

2.师:“大约130万个”是一个什么数?

生:是一个大概数,近似数。

师:求一个近似数要用什么方法?

生:四舍五入。

3.12756≈10000=1万 1389000≈1390000=139万

≈13000=13千 =1389千

① 师:我们要省略万后面的尾数应该怎么做?

生:首先找出万位,再看千位上的数是否满5,不满5就四舍,满5就五入,然后在把万后面的数改写成零或加一个万字。

② 请同学思考:如果是省略千、百后面的尾数又该怎么办呢?

做练习15页的“做一做”,然后在小组内交流。请小组派代表来汇报。

生总结:省略哪一个数位上的数要先找出那个数位,然后看到右边下一位是否满5决定四舍五入,但必须在后面加上省略那一数位上的计数单位。

三、巩固练习

1.第4题 由师生对答哪些是近似数,哪些是准确数。

2.第5题 由学生自己独立完成,然后开火车的形式校正,并要求说明过程。

3.第7题 由老师提示,讲解题意,然后让学生独立完成,同桌互对。投影校对,并让学生提出质疑。

4.第8题 学生独立完成,拿学生的课本投影校对,并请学生说明理由。

四、课堂小结

让学生说说这节课的体会,并答解疑难问题。

Dear Mr Wang:

We are so pleased that you are willing to share our views.

In the course of the general revision,What we need is solid foundation. Methods are vital,so could you please introduce some learning keys?We think it can help us much better.

Could you please teach us slower? We should have time to understand everything we learnt .Then we can learn the nature not the surface.

We also need to practice the important and easily wrong difficulties again and again. And we won\'t get puzzled when we meet the similar questions.

Doing homework is a way to make sure if all of us can control the knowledge.We hope that there will be less homework in order to increase the quality.

Besides,inspire us more and we\'ll do better than before.

Yours,

Li hua

DearAmy:

How are you? I guess it’spretty tiring to correct all that homework, I wonder if there areany shortcuts?

As a new teacher for ourclass, I think maybe you would like to know a few things about ourclass.

Um…… firstly, maybe you would like a real goodassistant. I recommend agirl, her English name is Amy too, Amy Lin. She’s really good atprocessing details, and, yes, carrying stuff (but not too much.She does everything really fast, and can leave enough timeleft.

Secondly, you might need a student-tutor, astudent that teaches other students. Well, I think a student whichhas “maths-craze” called Eric well be fit for the job. Hecan get good English grades as well, also, he loves helping otherswith their studies. He wears black and blue rimmed glasses all daylong, and maybe you know him. Many boys treat him as a boss, andare willing to listen to him.

Thirdly, perhaps you’re alsolooking for a student which can entertain the class and makeEnglish classes more interesting (a class clown. Then I recommendLeo, he jokes all day long, has a great sense of humor and crazyimagination. But he isn’t a classic good student, so perhapssometimes you’ll get a bit annoyed.

It’sabout ten! Maybe I’ll have to leave the rest for nexttime.

Bestwishes!
