When itcomes to a meaningful life, we might think of love, happiness and health. Alife filled with meaning is what most of us want for ourselves. Then, whatmakes a meaningful life?Manyresearchers agree that a meaningful life comes down to three factors (因素): havinglong-term goals, believing that one’s life matters, and feeling that one’s lifefits together and “makes sense”.But we believe there is more to consider. Sometimeslife enables us to experience small moments of beauty. When people are open toappreciating (欣赏) suchexperiences, these moments may improve how they see their own life. We callthis experiential appreciation (EA).
1.自学文本出示书中情境图:有21架飞机要参加飞行表演,怎样飞呢?想请同学们帮忙设计编组方案,下面小组同学合作,用学具摆一摆,设计出自己的编组方案,看哪个小组设计的方案最多?学生小组合作,边摆学具边说方案。2.交流研讨哪组想到前面来汇报一下你们制定的飞行方案?(不必强调平均分,如有小组同学说出每组有7(3)架,可以分成3(7)组,或每7(3)架一组,可以分成3(7)组,老师在给予肯定的同时可以问其它小组摆法一样吗?之后板书算式:21÷7=3,21÷3=7。如果学生没说出平均分,老师可引导说:有时表演的每组也可同样多)
活动过程:一、引导幼儿看范画,导入活动 师:“小朋友,这是谁啊?狮子是百兽之王。它代表着威武、吉利。人们都很喜欢它。今天,我们就要用版画的方式来表现狮子。把狮子的威武画出来。” 二、引导幼儿观察狮子的身体结构 1、引导幼儿看范画和幼儿共同分析狮子的特征。 师:“狮子长的是什么样子的?是什么颜色的?它喜欢吃什么?生活在那里?” 2、幼儿自由讨论交流。 小结:“狮子有一个长圆形的头,一双三角眼可历害了,最主要的是它那满头的毛看上去很威武,圆圆的身体,四条粗壮的腿,还有那一条像小棒一样的尾巴,尾巴末还有一小团毛。” (华令玲说:老师我在电视里看见狮子是金黄色的,它分身体圆鼓鼓的,很大。华楚楚说:狮子满身是毛,眼睛很凶。刘梦静说:狮子有胡子的,它的毛很长……) 幼儿对狮子比较熟悉,平时在图书、电视里经常能够接触到狮子,所以对于它的样子能够比较熟悉的描述出来。
泰山正南面有三谷。中谷绕泰安城下,郦道元所谓环水也。余始循以入,道少半,越中岭,复循西谷,隧至其巅。古时登山,循东谷入,道有天门。东谷者,古谓之天门溪水, 余所不至也。今所经中岭及山巅,崖限当道者,世皆谓之天门云。道中迷雾冰滑,蹬几不可登。及既上,苍山负雪,明烛天南;望晚日照城郭,汶水、徂徕如画,而半山居雾若带然。
活动目标:1、分享各自采访获得的感受,阅读相关的图片,进一步理解爷爷(奶奶)童年的故事,体验其中的艰难。2、运用实物比较感知发现两个时代生活条件的不同(吃、穿),初步体验今天生活的幸福。环境和材料创设:1、带补丁的衣服、黄面粉、蛋糕,绳子、ppt等。2、幼儿事先采访过爷爷奶奶,并记录
甲方因生产经营需要,经考核,录用乙方 (姓名)为 (工程名称)工人,遵照国家有关劳动法律法规,经双方协商,签订本合同。 第一条 甲方录用乙方从事 (工作名称)。 第二条 劳动合同期限从 年 月 日起至 年 月 日时止。其中试用期限为 个月,至 年 月 日止。
(2)∵点G是BC的中点,BC=12,∴BG=CG=12BC=6.∵四边形AGCD是平行四边形,DC=10,AG=DC=10,在Rt△ABG中,根据勾股定理得AB=8,∴四边形AGCD的面积为6×8=48.方法总结:本题考查了平行四边形的判定和性质,勾股定理,平行四边形的面积,掌握定理是解题的关键.三、板书设计1.平行四边形的判定定理3:对角线互相平分的四边形是平行四边形;2.平行线的距离;如果两条直线互相平行,则其中一条直线上任意一点到另一条直线的距离都相等,这个距离称为平行线之间的距离.3.平行四边形判定和性质的综合.本节课的教学主要通过分组讨论、操作探究以及合作交流等方式来进行,在探究两条平行线间的距离时,要让学生进行合作交流.在解决有关平行四边形的问题时,要根据其判定和性质综合考虑,培养学生的逻辑思维能力.
教学过程一、导入听辨乐器音色,思考问题:你听到了哪些声音?(由合成器演奏的不同音色的声音,如掌声、鸟鸣、流水,有旋律的梦幻般的声音,怪异的声音等。)生: 掌声、鸟鸣、流水等。师: 这些都是由一件乐器演奏出来的,什么样的乐器可以演奏出这么多种不同的声音?生:电子琴,合成器。师:这些乐器与我们所知道的西洋乐器和中国民族乐器有什么区别吗?生:有电。师:用这类乐器演奏的音乐通常被称为什么?生:电子音乐。师:今天我们就来学习电子音乐的相关知识。 二、电子音乐1. 电子音乐。电子音乐简称电音。其是20世纪50年代兴起的一种新音乐。任何以电子合成器、效果器、电脑音乐软件、鼓机等“乐器”所产生的电子声响,都可合理地称为电子音乐。2. 电子音乐发声原理。是用电子技术获得各种音源,用正弦波造成无泛音的所谓纯音,或用打击乐器、嘈杂乐器发出的杂音,也用人声和具体音乐相结合,通过声音滤波器和反响设备,使之变形、变质、变量,再经其他电子仪器和录音技术加以剪切处理,使之再生、复合,组成音乐作品。
2、能注意倾听他人讲述。 活动准备: 1、录音机、磁带、彩红屋黑板、透明胶。 2、小图片六张、一只没涂颜色的蜗牛。 活动过程: 1、 出示蜗牛(一只没涂颜色的蜗牛),引起幼儿的兴趣。 师:这是什么?(蜗牛)蜗牛走起路来是怎样的?谁来学一学?我们一起来学一学。 师:这只蜗牛的本领可大了,它会变颜色的,是一只变色蜗牛。猜猜看它会变成什么颜色呢?
