1、学习好资料欢迎下载儿童乐园教学设计教学内容:北师大版小学数学二年级上册第一单元教学目标:1.结合“儿童乐园”的生活情境,培养学生发现、提出和解决问题的意识与能力。2.在解决问题的过程中,经历把相同加数的连加算式抽象为乘法算式的过程,初步体会乘法运算的意义,体会乘法与生活的密切联系。3.会把相同加数的连加算式改写为乘法算式,知道它各部分的名称、读法,并应用加法计算简单的乘法算式的结果。教材分析:本节教材是北师大版小学数学二年级上册第一单元“数一数与乘法”的第2节课(第 4 页至第 5 页)。继上一节课“数一数”对连加算式有了一定体验的基础上,结合“儿童乐园”的现实情境,提出并解决其中需要列连加算
2、式进行计算的数学问题,并经历把相同加数的连加算式进一步抽象为乘法算式的过程,初步体会乘法运算的意义;会把相同加数的连加算式改写为乘法算式,体会学习乘法的必要性。教学重点:了解乘法的含义,学会用乘法算式解决问题。教学难点:理解乘法与加法的联系和区别。教学过程:一、创设情境,激趣导入。师:今天老师带你们到儿童乐园去玩,你们想去吗?(板书:儿童乐园)师:观察,你能提出哪些数学问题?二、活动探究,获取新知。1师:请大家仔细观察图片:(1)你观察到了什么?(2)根据这些信息你能提出哪些数学问题?生:有多少人坐小飞机?乘小火车的有多少人?坐在椅子上休息的有多少人?2学生独立思考并解决上面的问题,为抽象乘法
3、算式打基础。(1)坐小飞机的有:2+2+2+2=8(人)。(2)乘小火车的有:4+4+4+4+4+4=24(人)。(3)划小船的有:3+3+3=9(人)。(4)坐在椅子上休息的有:1+2+3=6(人)。3结合上述相同加数的连加算式,进一步抽象出乘法算式。师:像 2+2+2+2这样 4 个 2 相加,也可以用乘法来表示:24=8(人)或 42=8(人),(师边说边板书。)24 读作 2 乘 4,42 读作 4 乘 2。(学生跟老师读)4 2=8(人)乘乘乘积数号数学习好资料欢迎下载让学生向同桌介绍算式24=8(人)各部分的名称。4请学生结合上述解决“儿童乐园”中数学问题的过程,每人选择一道连加算
4、式,把它改写为乘法算式,并说一说可以改写的理由。生:我数了数有 6 个 4,就是 46=24(人)或 64=24(人)。师:“其中 4 是相同加数,6 是相同加数的个数。”生:我看到有 3 个 3 相加,就列式为 33=9(人)。生:老师,我发现两个乘数不一样时,可以列出另外一个乘法算式,两个乘数一样时,就只有一个乘法算式。师:你观察得真仔细!师:(指着算式 1+2+3=6)这个算式谁会用乘法表示?师:相同加数的连加算式。三、巩固应用。P19练一练。读图、列式计算。每个乘法算式中各个乘数的意义。四、总结:知道了求几个相同加数的和可以用乘法表示,用乘法表示比用加法表示更简;学会了乘法算式的读写法
5、。认识了乘法算式中各部分的名称。五、作业布置 19 页 2、3 题六、板书设计:儿童乐园2+2+2+2=8(人)4 2=8(人)或 24=8(人):乘乘 乘 积数 号 数4+4+4+4+4+4=24(人)4 6=24(人)或 64=24(人)3+3+3=9(人)3 3=9(人)或 33=9(人)1+2+3=6(人)文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7K4X1W6L8文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7K4X1W6L8文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7K4X1W6L8文档编码:CS7E4X6S7Z4 HF4Q9

12、与现实生活紧密联系”的课程理念。创设学生熟悉的的情境,让学生体会到用连加算式解决这类问题相对烦琐,激起学生学习乘法的愿望,进而感受学习乘法的必要性。学生初步认识了乘法运算的意义之后,让他们再找一找生活中有哪些问题可以用乘法表示,体会乘法与生活的密切联系。2把解决问题与学习乘法运算意义的过程结合起来,利用学生已有的用连加算式解决问题的经验,进一步抽象,建立乘法算式,从中体会乘法运算的意义。在列乘法算式时,“4 个 2”中的 4,“6 个 4”中的 6 和“3 个 3”中的第一个 3 是教学的关键,而对此学生往往容易疏忽。教师请学生说说自己列式过程中的想法,特别是从哪儿找到“4”“6”和“3”的,
13、由学生讲给学生听,更容易被学生所接受。另外,引发对“123=6(人)”为何不能用乘法算式表示的讨论,进一步强化对乘法运算意义的体验。总之,本节课的设计,能自始至终给学生创造出宽松的学习氛围,让学生在大量的生活情境中去体会、感悟和发现,真正让学生感受到了学习的乐趣,进一步激发了他们学习数学的愿望。文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7K4X1W6L8文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7K4X1W6L8文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7K4X1W6L8文档编码:CS7E4X6S7Z4 HF4Q9V7U8N6 ZG7
