1、表内乘法（一）第一课时乘法的初步认识教学目标1创设情境初步体会乘法含义，认识乘号，会读会写乘法算式。2培养学生动手操作及语言表达能力，鼓励学生小组交流合作学习。教学用具多媒体，小棒。教学过程一、创设情境1出示情景图。师：小朋友们，今天老师带你们去游乐园好吗？多媒体出示第44页主题图。2观察画面。师：仔细看一看，你都发现了什么？互相说一说。想不想把你看到的告诉其他的小朋友或者听课的老师呢？学生可能说：看到小火车、过山车、摩天轮、小桌子等等。看到小火车有 4 排座位，每排坐 3 个人二、探索新知1摆图形游戏。（1）（过渡）师：小朋友们可真聪明，给你们一幅图，你们就能想到这么多的问题，现在老师手里有

2、三根小棒，你能想到什么呢？（、个、工）我想摆两个三角形得用几根小棒？给你们4 根小棒，你能摆什么呢？（口、山、2 个人）4 根小棒的作用真不小，能摆口、山，还能摆 2 个人字呢。现在每个小朋友都有一捆小棒，你喜欢什么图形，就摆什么图形。开始吧。（2）摆图形听音乐。教师巡视，有目的地问几名学生。（3）交流。师：摆好了吗？给同桌说一说，你摆了什么图形？每个图形用了几根小棒？共用了几根小棒？并把算式写到题卡上。师：谁摆的是一样的图形，告诉老师。（板书三个加数相同的算式）文档编码:CY9S2U10Q7M5 HT1A7B6G1T2 ZD5A8U7R9I4文档编码:CY9S2U10Q7M5 HT1A7B6

17、7B6G1T2 ZD5A8U7R9I4师：求 6 个 3 是多少，还可以用乘法计算，就在6 和 3 的中间写乘号，看老师怎么写，先写“”，再写“”，伸出小手练一遍，这就是乘号，读作“乘”。我们读一遍。师：因为 6 个 3 连加是 18，6X3也是 6 个 3 连加的意思，所以 6X3也等于 18。这个算式读作：6 乘 3 等于 18。（板书）师：6 个 3 连加可以写成 6X3 18，还可以写成 3X618，这个算式会读吗？（板书“读作：3 乘 6 等于 18”）。师：观察这两个算式，你发现了什么？学生可能会说：两个数交换了位置；得数不变。4尝试。（1）师指第二个算式问：你能把这个加法算式改写

18、成乘法算式吗？互相说一说，谁来告诉大家（10X330，3X1030）。10 是什么？为什么要写 3？（2）师指第三个算式问：这个加法算式用乘法怎么表示，谁能上来写？（3）师指第四个算式问：这个算式能用乘法表示吗？为什么？（4）再看看自己题卡上的算式，能否用乘法算。能用的写出乘法算式，学生写完后投影出示。文档编码:CY9S2U10Q7M5 HT1A7B6G1T2 ZD5A8U7R9I4文档编码:CY9S2U10Q7M5 HT1A7B6G1T2 ZD5A8U7R9I4文档编码:CY9S2U10Q7M5 HT1A7B6G1T2 ZD5A8U7R9I4文档编码:CY9S2U10Q7M5 HT1A7B6
