1.复习亿以内数的'改写和求近似数。首先让学生举例说出一个含有两级的大数,其他学生在自己的本子上写出来,一生板演。根据学生举得例子要求将整万的数改写成“万”做单位的数,将不是整万的数,用“四舍五入”法省略万位后面的尾数,重点让学生说一说怎样改写和求近似数的方法。
2.“你能举例含有三级的大数吗?”老师的这个问题引发学生的兴趣,大家争先举例,板书呈现出来。
在我们成长的过程中,既有阳光雨露呵护,也有寒风雪霜相伴,它们都是人生的宝贵财富。经历与体验,使我们逐渐摆脱了蒙昧、幼稚,走向了成熟。
每次吃饭的时候,我都会在餐桌上掉下好些饭粒,大人们看着心疼,总会唠叨:“孩子,粒粒皆辛苦啊,你吃饭为什么总是掉饭粒呢?”
妈妈见我老是浪费,老是不改,就想了一个办法,她说:“从下顿饭开始,咱们数饭粒,如果掉下的饭粒比上顿多,多几粒,就从你零花钱中扣几元钱。”我认为这个条件对我是不公平的,为什么不说少几粒奖几元钱呢?
本以为妈妈是随便说说,谁知她却当了真,当天晚饭时我比中午饭多掉了三粒米,妈妈硬是从我的零花钱中扣掉了三元钱。我的`三元钱啊,能吃好几个雪糕,怎么就这样没了呢!
为了不让零花钱就这样白白流失,每逢吃饭时我都非常小心,确保掉下的饭粒要比上一顿少。有一次,我没有掉下一粒饭,全家人非常高兴,像看到什么大稀罕事一样直夸我,说我长大了,懂事了。我没想到自己仅仅做了这样一件小事,就能为家人带来这样的喜悦,为了能经常得到家人的称赞,每次吃饭我都小心翼翼,尽量不掉饭粒。
童年养成了不浪费粮食的习惯,后来上学了识字了,终于明白了“粒粒皆辛苦”的意思。粮食来之不易,它是农民伯伯用汗水换来的,所以我们要珍惜它,不能让农民伯伯的汗水白流。

Do you ever watch movies from other countries? Whenever I do, I think about how similar people really are all around the world. Even though the cultures and languages in those movies are different from mine, people all around the world are alike in their goals and emotions.
One time, I saw a movie made in china that showed parents helping their children with their homework. . My parents helped me the same way. Another time I saw a movie from Argentina. It showed school children playing hide and seek, which is a game I used to play with my friends during recess. Seeing these films demonstrated to me that education is a common goal in every country. Parents want their children to learn so their lives will improve. It also showed me that children in schools everywhere wants to play with their friends. Sometimes the games are similar to ours and sometimes they’re different. Still, they all have the common purpose of fun and learning to work together.
Earning a living is another common goal. I’ve often seen that in movies about other countries. In some countries, people choose their careers from what they like and are good at. In other countries, careers are chosen for them following the traditions of their families. But in every country it seems that people care a great deal about earning a living, and working hard is respected.
Showing people having fun together is always an important part of any movies, no matter what country it comes from. People everywhere want to be entertained, and want to spend time with their families and friends. Different cultures sometimes enjoy different activities, but all cultures enjoy some form of sports, music and dancing.
The movies I’ve seen make it clear to me that no matter the cultural differences between countries, people everywhere have the same basic needs and goals.

这部剧带给我许多快乐感动和泪水。完美学长修齐,女汉子罗曼,萌男张灏,婷婷,马俊才……这一个个角色深深地映在我的心里。
今天结局了,虽然最后不知罗曼和谁在一起,但这让我懂得了一个道理:有时爱情的最后结局不一定是要两个人在一起,只要曾经在一起快乐的生活过,拥有过美好的时光,这已足够。这是我一个未成年的学生感慨的。
修齐和罗曼从小就是青梅竹马,修齐一直在罗曼最难过,最需要帮助的时候第一个默默守护在他身边,保护她,永远为她着想着,给她最爱吃的面包,随时放着她最爱的面包,扛下她的错误,她受伤了自己比谁都着急给她买膏药……但张灏的出现又让她有了心动的感觉。如果换做任何人我想也应该会很难抉择吧!但对于罗曼来说这一年的夏天都不一样。
马俊才总是让我哭笑不得的人,最初他总是在不断寻找女朋友,但最后最爱他的人其实就在身边。婷婷最初一直喜欢着修齐,但最后发现了马俊才对自己的好,无论他们之间怎样吵过闹过,但最后发现对方就是自己想要遇见的那个人。
还有很多很多人物,却总是一言难尽。最后的学期和夏天假期的开始,一又二分之一的夏天这部剧陪伴我走过,今天大结局时,我又开始了永无止息的哭泣,这种舍不得似乎很久都没有过了。
现在的我们正处于青春期,青春是一场不散的宴席,青春不朽,我们都不知未来会发生什么,又怎么会又什么结局?夏天会一直陪伴着我们,虽然再美好也只是曾经,但到最后长大后的我们找到自己的曾经,或许会觉得自己正在经历着时光倒流的故事缩影。我们正在成长,未来的路还很长,在不知不觉中长大,许多东西,事早已发生了变化,我们要拥有正能量,学着包容,学着感激这个世界的一切,学着如何去爱,去冲向梦想的.未来,去面对未来的自己。
这部剧虽然结束了,但我们的夏天,我们的青春没有结束。人总要离别,但要笑着面对一切,笑着说再见。但缠绵回忆却总会闪现在脑海,让我们哭泣,我们不能逃避,现在不发生但这一切总是会发生的,只不过在你不经意的某个瞬间,身处某个地方,某年的某月某日而已。
让我们珍惜眼前的一切,享受夏天给我们带来的一切。希望这部剧还有第二部,希望这部剧一直陪伴着我们。这篇观后感虽然不是很长,但这包含了我对夏天这部剧浓浓的爱。希望夏天一直都在……
1.看,这些大数含有三级,你会读吗?这些数有什么特点?你能将它们改写成用“亿”作单位的数吗?对于学生举得例子中整亿的数,老师放手让他们自己改写(比较简单),改写后,说一说怎样改写的,应注意什么?
2.不是整亿的数省略亿后面的尾数求近似数,老师也是给学生充足的空间时间,自己尝试做一做。汇报交流时,重点强调,省略亿位后面的尾数关键要看哪一位上的数是否满五?
总之,学生自己能学会的知识,老师绝不包办代替,给学生留有空间,鼓励他们大胆尝试,利用已有的知识和学习方法自主探索,解决新的问题,提高数学能力。
