一、说教材《认识人民币》是人教版小学数学一年级下册第五单元的第一课时的内容。本课是让学生认识各种面值的人民币,初步知道人民币的基本知识和如何使用人民币,提高社会实践能力;另一方面使学生加深对100以内数的概念的理解,体会数概念与现实生活的密切联系。二、说教学目标1、学生能够正确的认识各种面值的人民币,知道人民币的单位元、角、分,知道1元=10角。 2、能较熟练地辨认各种面值的人民币。 3、感受数学与实际生活的密切联系。。教学重点:认识各种面值的人民币,知道人民币的单位元、角、分,知道1元=10角。教学难点:人民币的等价兑换。三、说教法、学法在整个教学过程中采用小组合作交流的学习方式,为学生设计猜一猜,看钱、认钱,唱歌、分类等活动。

1.统计是数学课程标准规定的四个领域之一。传统上比较注重统计图表等知识和根据统计图表回答问题的教学,而课程标准则更加重视学生对数据统计过程的体验,学习一些简单的收集、整理和描述数据的方法,认识统计的作用和意义。这部分内容比较繁琐,分小组进行合作学习是有效的学习方式。2.教师将教科书的盆花变成纸花,努力为学生创设一些数据,使教材更具有实用性。但是,对于有条件的学校,可以带领学生进行实地统计,效果会更佳。3.教师要善于捕捉课堂上学生的反馈信息,创设轻松愉悦的课堂气氛。本课中,教师设计的让学生学四种动物的叫声,不仅活跃了课堂气氛,又引入到下一个问题的探讨。4.充分尊重学生的选择,让学生用自己喜欢的方法进行统计,使他们的情感、态度在其中得到了充分体验。

教学内容:统一长度单位教材分析:通过量一量说一说想一想等活动切实感受到统一长度单位的必要性及其对生活的重要意义。学情分析:在上册“比一比”中学了比较物体长短的基础上学习的。尽管学生有这方面的经验和基础,但是长度单位的操作和应用是多种知识的综合,对小孩来说还是比较难的,在教学中应根据学生特点,注重实践性,培养观察力。教学目标:1、让学生通过量一量、说一说的活动,体验统一长度单位的过程,感受统一长度单位的必要性,为厘米、米的学习打下基础。2、让学生用不同实物作标准进行测量,培养学生的动手、思考能力,以及合作、估测的意识。3、通过不同的测量活动,让学生体验测量活动的过程,感受学习与生活的联系,体验学习数学的乐趣。

五、说教学过程 《观潮》这篇课文结构非常清楚,作者分别按潮来前、潮来时和潮头过后这三个方面向我们详细介绍了钱塘江大潮的壮观景象,课文的第一自然段为总写,重点描写了潮来时的景象。这篇课文不仅可以让学生积累好词佳句,还是一篇写作的好范文。为了使本课的工具性和人文性的统一,我设计了以下几个教学环节: (一)质疑导入,激起探究兴趣 导语“同学们,今天我们来学习《观潮》这一课。”(教师板书课题后质疑课题,什么是观,什么是潮?师生交流后回到课文中。)请同学们齐读课文第一段“钱塘江大潮自古以来被称为天下奇观”,提问“读到这儿,你有什么要问的?”学生会质疑“为什么说钱塘江大潮是天下奇观,奇在哪儿?”让学生展示课前搜集的资料再结合课后的资料袋说说钱塘江大潮形成的原因。{意图:让学生主动参与学习活动中来,激起学习新知识的欲望,为下一步的学习做好铺垫。}过渡语“同学们,我们知道了这儿的潮水是由于特殊的地形而形成的,那它究竟是什么样的呢,我们一起走进课文去感受感受。我们先把课文的障碍—生字扫除掉。”

二、在教育教学上,敬业爱岗,严谨治教 把学生教好,让学生成功,是每位教师最大的心愿、最高的荣誉。作为一名校本课程教师,最紧迫的问题是具有新的教学理念,刻苦钻研如何把花木文化与校本课程到达有机的融合,从而显现出我校的校本特色。在备课中,力图体现校本课程的综合性、开放性、实践性、体验性,把语文、数学、科学、美术课、音乐等整合进校本课程,围绕“花木文化提高学生的综合素质”这教学目标,有的课堂让学生观察写话,品析优美的文章,有的课堂让学生想象绘画,有的课堂让学生歌唱,欣赏名曲。在低年级尝试让学生经过观察、调查等开展探究性学习。此刻对于课程改革环境下的教师,光有一桶水是不够的,要根据学校与地方的实际,拓展学生学习资源。我注重研究现代教育技术在课堂教学中的应用,经过把本地的花木文化资源与网络资源相结合,进行教学资源的重组,尽量使课堂教学效果优化。所以孩子们还是比较喜欢上校本课的。

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分,只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

Step 5: After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century. He wanted to find the _3_____ of cholera in order to help people ___4_____ it. In 1854 when a cholera __5__ London, he began to gather information. He ___6__ on a map ___7___ all the dead people had lived and he found that many people who had ___8____ (drink) the dirty water from the __9____ died. So he decided that the polluted water ___10____ cholera. He suggested that the ___11__ of all water supplies should be _12______ and new methods of dealing with ____13___ water be found. Finally, “King Cholera” was __14_____.Keys: 1. doctor 2. 19th 3.cause 4.infected with 5.hit 6.marked 7.where 8.drunk 9.pump 10.carried 11.source 12.examined 13.polluted 14.defeatedHomework: Retell the text after class and preview its language points

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

一、 问题导学前面两节所讨论的变量,如人的身高、树的胸径、树的高度、短跑100m世界纪录和创纪录的时间等,都是数值变量,数值变量的取值为实数.其大小和运算都有实际含义.在现实生活中,人们经常需要回答一定范围内的两种现象或性质之间是否存在关联性或相互影响的问题.例如,就读不同学校是否对学生的成绩有影响,不同班级学生用于体育锻炼的时间是否有差别,吸烟是否会增加患肺癌的风险,等等,本节将要学习的独立性检验方法为我们提供了解决这类问题的方案。在讨论上述问题时,为了表述方便,我们经常会使用一种特殊的随机变量,以区别不同的现象或性质,这类随机变量称为分类变量.分类变量的取值可以用实数表示,例如,学生所在的班级可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多时候,这些数值只作为编号使用,并没有通常的大小和运算意义,本节我们主要讨论取值于{0,1}的分类变量的关联性问题.

Step 7: complete the discourse according to the grammar rules.Cholera used to be one of the most 1.__________ (fear) diseases in the world. In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention,the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste. The people who drank this water were much more likely _10_________ (get) cholera than those who drank pure or boiled water. Through John Snow's efforts, the _11_________ (threaten) of cholera around the world saw a substantial increase. Keys: 1.feared 2.when 3. nor 4.unless 5.that/which 6.infection 7.had gathered 8.removed 9.was polluted 10.to get 11. threat

4.写出下列随机变量可能取的值,并说明随机变量所取的值表示的随机试验的结果.(1)一个袋中装有8个红球,3个白球,从中任取5个球,其中所含白球的个数为X.(2)一个袋中有5个同样大小的黑球,编号为1,2,3,4,5,从中任取3个球,取出的球的最大号码记为X.(3). 在本例(1)条件下,规定取出一个红球赢2元,而每取出一个白球输1元,以ξ表示赢得的钱数,结果如何?[解] (1)X可取0,1,2,3.X=0表示取5个球全是红球;X=1表示取1个白球,4个红球;X=2表示取2个白球,3个红球;X=3表示取3个白球,2个红球.(2)X可取3,4,5.X=3表示取出的球编号为1,2,3;X=4表示取出的球编号为1,2,4;1,3,4或2,3,4.X=5表示取出的球编号为1,2,5;1,3,5;1,4,5;2,3,5;2,4,5或3,4,5.(3) ξ=10表示取5个球全是红球;ξ=7表示取1个白球,4个红球;ξ=4表示取2个白球,3个红球;ξ=1表示取3个白球,2个红球.

温故知新 1.离散型随机变量的定义可能取值为有限个或可以一一列举的随机变量,我们称为离散型随机变量.通常用大写英文字母表示随机变量,例如X,Y,Z;用小写英文字母表示随机变量的取值,例如x,y,z.随机变量的特点: 试验之前可以判断其可能出现的所有值,在试验之前不可能确定取何值;可以用数字表示2、随机变量的分类①离散型随机变量:X的取值可一、一列出;②连续型随机变量:X可以取某个区间内的一切值随机变量将随机事件的结果数量化.3、古典概型:①试验中所有可能出现的基本事件只有有限个;②每个基本事件出现的可能性相等。二、探究新知探究1.抛掷一枚骰子,所得的点数X有哪些值?取每个值的概率是多少? 因为X取值范围是{1,2,3,4,5,6}而且"P(X=m)"=1/6,m=1,2,3,4,5,6.因此X分布列如下表所示
