B、葡萄娃娃说“我比5少1” C、橘子娃娃说“我是1-----5数字中最小的那个数,是数字几呢? D、你们看看1----5数字中还剩下哪两个数呢?那西瓜娃娃和苹果娃娃谁是2谁是5呢?西瓜娃娃说:“我的数字比苹果娃娃大,谁能告诉大家是几?那苹果娃娃是数 字几? (2)巩固 现在老师看看你们记住了没有,加以验证。师指认每个水果娃娃,让幼儿说出背后的数字。 (3)猜猜少了哪个数? 现在老师任意拿走一样水果,问少了几,是什么水果,重复指认水果和数字。
活动目标:1、感受生活中有规律的序列,产生对规律活动的兴趣。2、能仔细观察、主动探索,感知规律的主要特征。3、尝试自创规律,发展幼儿的实际运用能力。活动准备:1、有色彩排列出规律的衣服。2、可以串挂的小积木若干,穿挂用的绳子人手一根。3、生活中有规律事物的课件(照片以幼儿身边场景为主)。
2、发展幼儿的逻辑思维能力。3、教育孩子珍惜时间,养成按时作息的好习惯。活动准备:1、幼儿人手一份硬纸片钟。2、动物手偶3、实物钟活动过程:一、引入并简单认识钟及其作用。1、 引入并简单认识钟的种类及其作用。教师调闹钟闹铃引入提问:⑴你们猜猜是什么声音?(闹钟的闹铃)⑵家里还有哪些钟?是什么形状的?(有闹钟,手表,挂钟和大座钟)⑶钟有什么作用?(钟不停的走,告诉人们几点了,人们就按照时钟上的时间进行学习休息)2、简单认识钟面。教师:今天老师也带来了一个钟,看看它是什么形状的?(圆形)请你仔细观察钟面上有什么?总结:有两根针和12个数字。提问:⑴这两根针有什么不同?(长度不同)教师:他们都有自己的名字,长的叫分针,短的叫时针。我们在看看数字,提问:⑵正上面的是数字多少?(12)⑶正下面的是数字多少?(6)二、由时针、分针赛跑,引导幼儿感知时针、分针的运转规律。教师:今天呀,时针和分针要进行依次跑步比赛,现在他们都摘在数字12的起跑线上了。请你们猜猜谁回赢?好,比赛就要开始了,预备— 开始!(教师操作钟表)提问:⑴谁跑的快?(分针)议论:分针和时针跑的时候,他们之间有什么秘密呢?教师反复操作。总结:分钟走一圈,时钟走一格,这就是一小时。
活动目标:通过实践活动,学会用自己的方法分类统计生活中物品的数量,从中体验数学的有趣及重要。活动准备:教师事先选择好实践的场地(幼儿园内),并亲自实践一遍做好记录,心中有数;纸、笔。活动过程:(一)复习巩固:1、你能从1数到几?数数看。2、更快的数数方法:5个5个地数,10个10个地数。3、100以内的随便一个数你会写吗?试试看(请几个幼儿到黑板上听写)。(注:此环节的目的在于教师了解幼儿在实践活动中必备的一些相关知识掌握如何,以便在活动中更好地把握。)(二)联 系生活:1、在生活中,你碰到什么东西要用数来数?举例子。2、在幼儿园里也藏了许多数,请小朋友们说说。3、用什么方法统计方便?(每5个或10个记录一次,然后5个5个或10个10个地数;列表统计等)
重点:了解接龙游戏的规律,并能运用比较、对应的经验合作制作接龙卡。难点:1.孩子对前后卡片的界限区分。成因是接龙卡本身有两小部分所组成,容易会造成孩子辨别卡片上的混淆。2.操作中的前后推理。成因是由于幼儿的逆向思维发展尚不成熟,容易被附近一个已知数所误导。解决策略:1.逐步化解法:借助双色的卡片做教具,以层层递进的方式从顺向推理向逆向推理逐步过渡。2.资源共享法:以小组合作形式开展操作活动,能以兵兵互教的形式化解补缺的难点,达到资源共享。活动目标:1.了解接龙游戏的规律,并能运用比较、对应的经验合作制作接龙卡。 2.尝试用简洁语言介绍和交流自己的操作结果,能运用以往的数学经验表明意思。
