Dear teacher,
We'll have a class meeting this afternoon. All of us students hope that you can attend it. Please accept our sincere invitation. I
n the class meeting, we will make some plans about all the subjects, including English. We do have some puzzles and we need your help. So we hope you can set some time aside to be with us in the class meeting. We will feel honored if you can come to attend our class meeting.
Looking forward to your coming.

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

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。
3.1275610000=1万 13890001390000=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 teacher:
Let me introduce one of my friends to you.
His name is Liming . He graduated from Beijing University and major in English. He started learning English since 12 years old. His parents have a lot of American friends. That’s why he has no problem communicating with Americans or others by speaking English.In his spare time, He like to do anything relating to English such as listening to English songs, watching English movies or TV programs, or even attending the activities held by some English clubs or institutes. He used to go abroad for a short- term English study. During that time, He learned a lot of daily life English and saw a lot of different things.Now he is my best friends .We often communicate in English .I can learn some fresh things from him.

秋天是硕果累累的。黄澄澄的柿子像一个个灯笼高挂枝头,红彤彤的苹果像一张张胖娃娃害羞的脸,绽放着笑容,亮晶晶的葡萄像黑珍珠般透射出诱人的色彩……赏心悦目之余垂涎欲滴的。
秋天是风景优美的。花园里,菊花在尽情的开放,阵阵幽香扑鼻而来,使人立刻觉得神清气爽。行人看到这美景,闻到阵阵幽香,情不自禁的停下脚步,拍照留念,细细观赏,直到恋恋不舍的离去,这才发现,烦恼早就抛到九霄云外去了。
秋天是五彩缤纷的。枫叶是火红的,那一片片火红的枫叶从树上纷纷扬扬的'飘落下来,像一只只蝴蝶在空中翩翩起舞。这是你仿佛置身于红色的海洋。稻谷是金黄的,田里的稻谷已经成熟了,金黄一片,农民伯伯在地里收获庄稼,虽然很辛苦,但脸上却洋溢着幸福的笑容。
秋,你拥有独特的美,无可比拟的神韵。哦!秋之神韵,我欣赏你;秋之高洁,我赞美你。
