人教版新课标小学数学一年级下册多些、少些、多得多、少得多说课稿
在100以内数的范围里，18比50是少得多，但到了万以内数的范围内，可能只是少一些，所以结合具体情境帮助孩子体会是很重要的教学方法。想想做做第1题是小孩在进行拍皮球比赛，让孩子选合适的答案，在小组中说说是怎么想的，孩子在交流中就能体会到12比46少得多，50比46多一些，85比46多得多；想想做做第2题是发生在校园里的一个场景，让孩子自己选合适的答案，说说怎么想的，孩子就能体会到16比38少的多，36比38少一些，40比38多一些；第3题的场景是在商店里，让孩子先讨论、认识“贵多啦”的含义，在进行选择，在选择、辨析时进一步明白贵多啦就是“用的钱多得多”；最后，和孩子进行一些活动，比比身高（孩子和孩子比、老师和孩子比）、比比身边的一些数量大小，让孩子尝试用语言描述的同时体会数量之间的大小关系，感受到数学就在身边。最后由一个游戏结束本节课，让孩子拿一个数同45比一比，自己想两个数让同桌比一比，练习使用多些、少些多的多、少的多描述两个数量之间的大小关系，增强合作能力。
人教版新课标小学数学三年级下册用连乘解决问题说课稿2篇
3、小结比较观察三种方法，提出问题：为什么同一个问题有三种不同的解决方法？学生交流，教师小结：先解决的问题不同，选择的信息不同，图形拼摆的不同，解决的方法就不同，体现数形结合的思想。相同点是：无论思路如何，都是用连乘的方法解决问题。板书课题：解决问题——两步连乘应用题生活中还有很多这样的清况，想不想再尝试一下。（三）联系生活，优化方法，拓展深化，学校有特异为这些参加比赛的同学们购买了矿泉水，出示画面：共有20箱矿泉水，每箱24瓶，每瓶2元，请问学校共要支付多少钱？学生独立完成观察和思考的角度不同，先后选择的信息不同，所以同一道题有不同的解决方法。看来大家多用连乘的方法解决问题有了进一步的理解。生活中类似这样的问题很多，再来看一看：学校定好了水，付了钱，总得运回来吧.出示搬运车搬水到卡车上的画面：搬运车一次搬4摞，一摞3箱，一箱24瓶，请问搬运车一次能搬多少瓶？
第二周国旗下讲话稿：发扬宏志精神，实现青春跨越
老师们，同学们，大家好！今天我国旗下讲话的题目是《发扬宏志精神，实现青春跨越》。XX年9月，宏志班在xx市xx实验中学创立了。从那时起到今天，历经三年时光，自强不息的田中人用青春和汗水换来了宏志大树的刚健与挺拔，铸就了xx中学今日的丰硕与芬芳。特别是XX年、XX年两年中考，宏志班的同学取得了优异的成绩，有90多名宏志生录取到四星级高中，圆满的完成了教育局下达的扬中、附中指标，这些数据不断刷新着田中教学质量的新高度，赢得了家长、社会的刮目相看和高度赞誉。喜人的成绩面前，我们追寻原因：到底是什么让田中学子不断书写美丽的传奇？我想：应该就是宏志精神。什么是宏志精神呢？宏志精神的核心就是“自强、勤奋、感恩”。《易经》中说：“天行健，君子以自强不息”。古往今来，成就大事之人，都是自强之人。勾践卧薪尝胆，实现了“三千越军可吞吴”的壮举；祖逖闻鸡起舞，赢得了东晋军事家的美名；曹雪芹披阅十载，增删五次，铸就了《红楼梦》的绝世经典。人生的道路漫长而又精彩：我们要学会在阳光中欢笑，在阴霾中坚强，在狂风中抓紧希望，在暴雨中坚守理想；自强不息，乐观向上，走出一条属于自己的人生之路。
春季学期第二周国旗下讲话稿：争做文明学生，共筑美好校园
老师们，同学们，大家早上好！今天我国旗下讲话的主题是：争做文明学生，共筑美好校园。大家知道做什么事情不简单、做什么事情不平凡吗？把每一件简单的事情做好，就是不简单；把每一件平凡的事情做好，就是不平凡。我的一个好朋友，每次在食堂吃完饭，都会一边把盘子递给收餐具的阿姨，一边礼貌地对她说声“谢谢”。收餐具的阿姨通常忙得顾不上回答——她们正以最快的速度整理着几只手同时甩在桌上的餐盘。不过也有时候，阿姨会冲我们笑笑，或者开心地说“不用谢”，然后继续麻利地工作。我不知道这一句简单的“谢谢”能有多大的作用，不过我想，至少这个阿姨的一天可以因此多一丝愉快，我们的校园里可以多一点文明的正能量。

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教学设计二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.
