  • 人教版新课标小学数学一年级下册人民币的简单计算教案

    人民币的简单计算是在对人民币的认识后,是人民币的再进一步的认识。本节课的主要知识点主要有三个:一人民币单位间的换算、二进行简单的计算,三是知道商品价格的表示形式。同时通过这节课的学习,逐渐培养交往和社会实践能力,体会人民币在社会生活商品交换中的作用。为了达成以上的一些目标我是这样设计这节课。一、从学生经验入手直接引入商品价格,在学生回忆商品价格的表示方法中,唤醒学生的思绪,使学生觉得在所学的知识与实际生活的联系。让学生体验到数学与日常生活的密切联系。二、在操作中完成进率的换算。进率的换算在教学是一个重点也是难点,为此我在教学上通过不同的的付钱方法,深刻体会,这样的教学让说不清的关系,在操作讲解中得以内化。学生学了也不易忘记。

  • 初中历史与社会人教版九年级下册《地球一小时 活动》教材教案

    地球一小时(Earth Hour)是世界自然基金会(WWF)应对全球气候变化所提出的一项倡议,希望家庭及商界用户关上不必要的电灯及耗电产品一小时。来表明他们对应对气候变化行动的支持。过量二氧化碳排放导致的气候变化目前已经极大地威胁到地球上人类的生存。公众只有通过改变全球民众对于二氧化碳排放的态度,才能减轻这一威胁对世界造成的影响。地球一小时在3月的最后一个星期六20:30~21:30期间熄灯。活动由来:“地球1小时”也称“关灯一小时”,是世界自然基金会在2007年向全球发出的一项倡议:呼吁个人、社区、企业和政府在每年三月最后一个星期六20:30~21:30期间熄灯1小时,以此来激发人们对保护地球的责任感,以及对气候变化等环境问题的思考,表明对全球共同抵御气候变暖行动的支持。这是一项全球性的活动,世界自然基金会于2007年首次在悉尼倡导之后,以惊人的速度席卷全球,大家都来参加这个活动。[1] “地球1小时”活动首次于2007年3月31日在澳大利亚的悉尼展开,一下子吸引了超过220万悉尼家庭和企业参加;随后,该活动以惊人的速度迅速席卷全球。在2008年,WWF(中国)对外联络处透露,全球已经有超过80个国家、大约1000座城市加入活动。2013年,包括悉尼歌剧院、帝国大厦、东京塔、迪拜塔、白金汉宫在内的各国标志性建筑也在当地时间晚八点半熄灯一小时。[2] ,其中包括巴勒斯坦、法属圭亚那、加拉帕戈斯群岛、卢旺达、圣赫勒那岛、苏里南、突尼斯等首次参与“地球一小时”的国家和地区。在中国,北京鸟巢、水立方、世贸天阶等标志性建筑同时熄灯,同一时段,从上海东方明珠到武汉黄鹤楼,从台北101到香港天际100观景台,中国各地多个标志性建筑均熄灯一小时,全国共有127个城市加入“地球一小时”活动。

  • 人教版新课标小学数学五年级下册设计镶嵌图案教案

    师:同学们,在四年级的时候,我们已经了解了图形的密铺,请你说一说,什么是图形的密铺?(没有重叠、没有空隙地铺在平面上,就是密铺。)师:图形的密铺又可以叫做镶嵌,以上四个图片,都是由哪些基本图形密铺(镶嵌)而成的呢?(请学生边指边说。)师:还有哪些图形也可以镶嵌?(学生可能回答:三角形,平行四边形,梯形,菱形,正六边形,……)师:今天就请你发挥一下想象力,设计一些与众不同的镶嵌图形。[设计意图说明:学生在四年级已经初步了解了图形的密铺(镶嵌)现象,四幅图片是四年级下册教材《三角形》单元中《密铺》内容中的原图。本单元在此基础上,通过数学游戏拓展镶嵌图形的范围,让学生用图形变换设计镶嵌图案,进一步感受图形变换带来的美感以及在生活中的应用。]二、新授探究一:利用平移变换设计镶嵌图形

    1.自己选择植物的花瓣(牵牛花、月季花)、蔬菜(紫卷心菜、胡萝卜) 在研钵中捣烂,加入酒精(它有消毒作用,可使制得的指示剂长期 保存)浸泡,用纱布将浸泡出的汁液过滤或挤出,就得到指示剂, 2.把制好的指示剂装入试剂瓶,贴上标签备用。 把食醋、稀盐酸、稀氢氧化钠、澄清石灰水,分别滴在两个 白色点滴板上,用石蕊、酚酞分别滴在上述溶液上,通过颜 色变化检验它们的酸碱性。 用玻璃棒分别蘸取上述溶液,滴在pH试纸上,然后对照标准 比色卡比较,得出pH值,也就是酸碱度。 把上述溶液滴在白色点滴板上,用滴管吸一下你自制的指示剂,滴在滴板的溶液里,观察颜色变化,每用一种指示剂,换一下滴板的溶液。 把所得到颜色变色变化的信息和pH值数据填入教材第70页的表中。 3.取少量土壤样品,将土壤样品与蒸馏水按1∶5的质量比在烧杯中混合, 充分搅拌后静置,用玻璃棒蘸澄清的液体,滴在pH试纸上,然后对照 标准比色卡记录读数。

  • 人教版新课标小学数学五年级下册因数与倍数教案

    因此,本套教材中删去了“整除”的数学化定义,而是借助整除的模式na=b直接引出因数和倍数的概念。在本册教材中,由于允许学生采用多样的方法求最大公因数和最小公倍数,分解质因数也失去了其不可或缺的作用,同时,也是为了减少这一单元的理论概念,教材不再把它作为正式教学内容,而是作为一个补充知识,安排在“你知道吗?”中进行介绍。由于这部分内容较为抽象,很难结合生活实例或具体情境来进行教学,学生理解起来有一定的难度。在过去的教学中,一些教师往往忽视概念的本质,而是让学生死记硬背相关概念或结论,学生无法理清各概念间的前后承接关系,达不到融会贯通的程度。再加上有些教师在考核时使用一些偏题、难题,导致学生在学习这部分知识时觉得枯燥乏味,体会不到初等数论的抽象性、严密性和逻辑性,感受不到数学的魅力。所以在教学中应注意以下两点: (1)加强对概念间相互关系的梳理,引导学生从本质上理解概念,避免死记硬背。(2)由于本单元知识特有的抽象性,教学时要注意培养学生的抽象思维能力。
