(2)圆锥的体积教学内容:第25~26页,例2、例3及练习四的第3~8题。教学目的:1、 通过分小组倒水实验,使学生自主探索出圆锥体积和圆柱体积之间的关系,初步掌握圆锥体积的计算公式,并能运用公式正确地计算圆锥的体积,解决实际生活中有关圆锥体积计算的简单问题。2、 借助已有的生活和学习经验,在小组活动过程中,培养学生的动手操作能力和自主探索能力。3、 通过小组活动,实验操作,巧妙设置探索障碍,激发学生的自主探索意识,发展学生的空间观念。教学重点:掌握圆锥体积的计算公式。教学难点:正确探索出圆锥体积和圆柱体积之间的关系。教学过程:一、复习1、圆锥有什么特征?(使学生进一步熟悉圆锥的特征:底面、侧面、高和顶点)
学生活动:阅读课本,找出问题。教师点评:纸币是由国家发行的,强制使用的货币符号。因为在商品流通中,人们只关心货币能否带来价值相等的商品,不关心它本身是否足值,所以,可以用货币符号――纸币,代替它执行流通手段职能。这样就产生了纸币。教师活动:既然国家有权发行货币,是否可以随意决定纸币的发行数量呢?(2)纸币的发行规律 纸币的发行量必须以流通中所需要的货币量为限度。发行过多会引起物价上涨,;发行过少,阻碍流通。生活中出现的通货膨胀、通货紧缩现象,往往是与货币发行违反发行规律有重要关系。(3)制造假币是违法行为教师活动:请同学们阅读教材P6-7页,说明刑法中的这些规定对你有什么启示?学生活动:阅读课本,探索问题。教师引导:通过学习这些规定,应该明确:制造假币是一种违法行为,应受到法律制裁;人民币在我国经济和人民生活中有十分重要的作用,爱护人民币是每个公民的责任;要提高鉴别假币的能力。
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.

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。

一、知识和能力目标本单元的核心教学内容是“认物”。用英语确认周围的常见事物比较符合英语初学者的实际情况。通过本单元教学,使学生运用所学句型,去熟悉周围事物的名称;教学生学会在实际生活中如何确认事物。通过辨认物体,学生学到一些生词,并巩固所学句型。二、过程和方法目标教师要尽量使学生对课文中出现的句型能够熟练上口,这样,学生才能顺利开展比较灵活的对话。教师可以用手势,表情,动作等示意,帮助学生听懂课堂教学内容,但在实际操作中应尽量避免“明知故问”的倾向,应该采用应用性原则;如:遮盖物品、显露局部、辨认物体、完形识别、图形辨认等方法。三、情感态度和价值观目标目标在学生学习过程中的作用至关重要,教师要帮助他们建立起一个切合自己实际的目标,通过渐进的学习以及一点一滴的进步,使他们逐步建立起成功感。成功越多,自信心就越强。
三、教学建议第一课时:1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places.

Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3.
