(6)交流。6的乘法口诀一共有几句?口诀中的第一个数与算式中的第二个因数相同,表示什么?口诀中的第二个数与算式的第一个因数相同,表示什么?相邻两句口诀的积相差几?哪几句难记一些?你用什么方法记呢?怎样记住"三六十八"、"四六二十四"两句口诀?教师在学生发言的基础上鼓励学生大胆说、想出不同记口诀的方法。(7)应用"做一做"第1题(学生半独立完成):①用6根小棒摆1个六边形;②摆2个六边形要用多少根小棒?你是怎样想的?(想口诀"二六十二"。)③运用所学的口诀口答摆4个、6个、3个、5个六边形所需要向小棒数。"做一做"第2题(独立完成):①将第2题改为填空题,在圆圈内填写正确的积;②口答得数,并说一说所用口诀。
教学目标:1、通过多种形式的练习,提高学生的计算速度和正确率。2、培养学生看图表的能力,初步渗透统计思想。3、培养学生学习数学的兴趣,同时培养学生的数感。教学重、难点:熟练掌握计算方法并能够进行正确的计算,能够有效的提高计算速度及正确率教学过程:一、基本练习1、口算10-38+49-1 9-88+215+38+77+55+6 3+911-19+68+86+78+6 9+82+93+102、()里应填什么数?(1)比9大2的数是(),比7多4的数是()。(2)写出得数是13的四道算式?( )、()、( )、()(3)练习9+()=13 8+()=1512-()=2()+7=14()+()=12 ()+()=19二、指导练习练习二十一第4题(1)学生看书,弄清题目的意思。问:这题是什么意思?(2)分组讨论,并派代表说一说。(3)教师板书,引导学生看统计表。指导学生看表:表的第一竖行画有皮球、毽子、跳绳;第二竖行上面写着“一班有”,下面的数就是一班有这三种体育用品的数量,即一班有7个皮球、5个毽子、4条跳绳;
一、激趣导入同学们,你们想去动物园吗?今天我们就跟着亮亮和晶晶一起去动物园逛一逛,好不好?(打开课件,指出亮亮和晶晶,说他们手里还拿着漂亮的气球,为下面的观察作铺垫)动物园里可真热闹,天上还有4只小鸟也在跟着凑热闹,注意观察,你看到了什么?(飞走了1只小鸟)。二、探索新知1.减法的意义(1)认识减号原来有4只小鸟,飞走了1只,就是从4里面去掉1,“去掉”用什么符号表示?板书“-”,并让学生伸出小手和老师一起写。用减号表示的算式叫作减法算式。从4里面去掉1,就用减法计算。不仅这个用减法,只要是从一个数里去掉一部分,就要用减法计算。(2)写算式用算式怎样表示呢?4-1=3(只)“4”表示原来有4只小鸟,“1”表示飞走1只也就是去掉1,“3”表示还剩3只小鸟。去掉的数写在减号后面,原来的数写在减号前面,剩下的数写在等号后面。这个算式就表示从4里面去掉1,还剩3.
(二) 呈现新课 (Presentation)1、教师出示学过的缩略语PRCUKCANUSA让孩子读一读,然后拿出相应的卡片贴在黑板上请掌握较好的学生带着同学们读一读缩略语2、出示课文中的缩略语,让孩子们自己试着读一读,然后试着说说缩略语的含义3、听录音,跟读。小组说说4、让孩子们介绍自己收集的生活中的缩略语教师给以适当的扩充:CCTVWTOUFO等5、教师分别出示大小写Hh,让孩子想想大小写的字母分别想什么,用语言描述或是用动作表示。6、Let’s chant听录音,边听边打节奏听录音,边听边出示相应的字母听录音,边听边试着说歌谣孩子们带上自己的头饰,在小组中边演边说各小组展示(三)趣味操练(Practice)1、listen and order the cards让孩子说字母,按照听到的顺序排列字母2、listen and guess教师拼一拼缩略语,孩子快速说出词小组游戏(四) 扩展性活动(Add-activities)纸牌游戏两个孩子分别有一套学过的字母卡,按顺序出卡片,看谁能最先组成一个学过的缩略语。【板书设计】
(一)创设问题情境:师:小朋友,你们喜欢老师漂亮一点呢还是喜欢老师丑一点?生:大多数的小朋友说喜欢老师漂亮。师:那你们帮助老师打扮打扮。我最喜欢红色体恤和这三件下衣,到底怎样搭配最漂亮呢?请小朋友们给老师出出主意。小朋友们纷纷发表自己的意见,并说出了自己的理由。师:谢谢。你们的建议都不错。那我这一件上衣、三件下衣能有多少种不同的穿法呢?老师接着问:那我有两件上衣、三件下衣又有多少种不同的穿法呢?有说4种、有说5种、也有说6种的,到底有几种呢?(二)1.自主合作探索新知试一试师:请同学们也试着想一想,如果你觉得直接想象有困难的话可以借助手中的学具卡片摆一摆。学生活动教师巡视。2.发现问题学生汇报所写个数,教师根据巡视的情况重点展示几份,引导学生发现问题:有的重复了,有的漏写了。
教学设计理念:英语课程标准明确指出,学生的发展是英语课程的出发点和归宿。小学英语课的主要目标是培养学生用英语做事情的能力,同时重视学科内容的有效融合。新课程提倡任务型教学,让学生在教师的指导下通过感知、体验、实践、参与和合作等方式完成教学目标。本着这一理念,我在设计本课时从激发和保持学生的学习兴趣入手,精心创设生活化语言情景,开展丰富多彩的活动,让学生在我的指导下进行语言交流,感受用英语交流的乐趣和成功感,从而培养学生用英语进行交流的能力。教学目标:1. 情感目标:关注学生的内在需要,在活动中培养学生的协作精神和竞争意识,培养学生学习英语的积极情感态度。2. 知识目标:能运用所学语言进行交流。3. 能力目标:通过本课的学习,学生能在实际生活中用英语进行问候;培养学生在课堂上进行自主评价的能力;培养学生根据情景猜测语义和在尝试中自我修正的学习策略。
4 课堂评价 (Assessment) (1)做活动手册本单元第3、4、5 部分的练习。练习3是检测学生的词汇掌握情况。教师可以让学生组成两人组进行看词快说的比赛,说对一个词涂一朵小花,比谁的花多。练习4是让学生看词涂色,说说两种颜色的结合会变成什么颜色,并将第3种颜色涂在圈中。教师可以给学生做一个示范,然后再让学生动手实践。此练习是机动性练习,教师可根据时间分配情况灵活安排。练习5 是让学生将句子和相对应的图连线,教师可以先让学生看图,猜图上人说的话,然后再连线。此练习是检测学生对句子的整体认读能力,不需要学生认识句子中的每个单词。练习后,根据学生情况进行简单小结。给学生适当的奖励。(2)让学生自我评价半学期的英语学习情况,可在第37页上做标记,看看自己能达到什么程度。对于评价结果不太理想的学生,教师要及时鼓励,教育学生不能灰心放弃,针对这部分学生具体的情况在课后进行进一步交流。
【教学过程】一、从实际情景入手,引入新知,使学生学会在具体情景中用数对确定位置1.谈话引入。今天有这么多老师和我们一起上课,同学们欢迎吗?老师们都很想认识你们。咱们先来给他们介绍一下我们班的班长,可以吗?2.合作交流,在已有经验的基础上探究新知。(1)出示要求:以小组为单位,想一想,可以用什么方法表示出班长的位置,把你的方法写或画在纸上。汇报:班长的位置在第4组的第三个,他在从右边数第二组的第三排…哪个小组也用语言描述出了班长的位置?请班长起立,他们的描述准确吗?刚才同学们的描述有什么相同和不同?(都表示的是班长的位置,有的同学说第几组,第几行,第几排……)看来在日常生活中,我们可以用组、排、行、等多种方式,还可以从不同的方位来描述物体的位置。为了我们在确定位置的时候语言达成一致,一般规定:竖排叫列,横排叫行。
1.小组学习法全班分成各个部位,以半弧形状摆设,不仅拉近了师生、同学间的距离,便于口语交际和合作学习,而且让学生在独立与合作的交织中变得大胆、自信。2)Learning by singing, chanting, playing, touching.通过这些活动激发学生学习英语的兴趣,帮助他们建立学习的成就感和自信心。四.教学步骤英语课程的学习即是学生通过英语学习和实践活动逐步掌握语言知识,技能,提高实际运用能力的过程,又是他们陶冶情操,拓宽视野形成有效学习策略的过程。整个教学我设计了复习——新知展示——练习——小结及作业布置四个步骤。一.Warm-up1.Geetings2.SingasongT:Do you like to sing a song?Ss: Yes.T: Now, Let’s sing as ong,OK?Ss:OK. 【教师和学生一起边拍手边唱这首歌,不仅复习前面的打招呼语,而且把学生拉回到英语课堂,活跃了课堂的氛围,增加学生的学习兴趣】3.guessinggameT: Good. Look at me, What’s in my hand ?【教师拿出一个书包,书包内装入了各种学过的文具和一个玩具人头,让学生感到新奇,从而增强兴趣】
五、总结存储1.教师总结这篇演讲词,作者用幽默诙谐的语言阐述了自己人生中的一个重要抉择——大力扶植年轻人。作者善于自我调侃,在自我解剖中进行了深入的分析,强调了扶植年轻人的重要性和必要性。演讲中列举了大量名人事例进行论证,使演讲具有很强的说服力。这篇演讲词展示了一位科学家精彩绝伦的语言魅力:不但有科学原理,而且有人生哲理;不但有学术的穿透力,而且有情感的震撼力;不但有理论的清晰度,而且有语言的幽默感——这一切构成了王选演讲的独特风采。我们在体会王选演讲魅力的同时,也领略到了他的人格魅力。2.布置作业(1)人的一生所做的重要抉择,如果与时代和国家紧密相连,意义会更加重大。我们在人生的关键阶段,如选择未来事业时,会做出怎样的抉择?请你写一段200字左右的演讲词,并在小组内演讲交流。(2)课外阅读王选的《我一生中的八个重要抉择》。
