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

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.

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.

得到13－8=这个算式后，我让小朋友们想办法，“13－8怎么算？你是怎样想的？把你的想法告诉你小组的同学们。”由于我是用讲故事的形式引出这一问题的，因此在计算13－8时，小朋友们就被迫要自己想办法去计算，而不能光借助情境图去直接数出得数。这并不阻碍算法的多样化，相反更好地实现了算法多样化的目的，真正让学生成为了数学学习的主人。为了增加这堂课的趣味性，我有意将学生说出来的各种算法分别以他们的名字来命名，这样一来，学生兴趣盎然，都积极投入到了寻找算法的思考活动中来了。在寻求多样化的过程中，充分发挥了学生学习的主体性，培养了学生的创新精神，让每一个学生都能体验学习的成功。学生们在思考、讨论中可能会出现这样几种算法：
人教版新课标小学数学一年级下册数的组成 说课稿3篇
一、说教材分析教材分析：本部分内容是在学生认识了认数的第一阶段—20以内各数认识的基础上，扩展到认数的第二阶段—100以内各数的认识。本阶段的数概念不仅是学习100以内数计算的基础，也是认识更大的自然数的基础。它在日常生活中有着广泛的应用，因此必须使学生切实学好。在分析教材的基础上，灵活的运用教材，我认为开始的主题图，如果10只一群地出示，虽然有利于学生估数，但这样学生能很快地10只10只地数出羊群只数是100，在后面数100个物体的个数时，就会受其影响而10个10个地数，这样的数法，要在学生会逐个数数的基础上自然生成，其实，它比一个一个地数要高一个层次，数数单位由“一”变成了“十”，不利于学生把100以内的数逐个数出来，因此，我把主题图的出示放在了一个一个数物体之后。
人教版新课标小学数学一年级下册统计 说课稿5篇
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。
