教学中要注意引导学生去发现列竖式的方法，体会数位对齐的基本规律。
同时要求学生与加减法竖式进行比较，体会乘法竖式与加减法竖式的区别。
二、学情分析：学生对乘法口诀已基本掌握，对乘法竖式的教学奠定了基础，同时也为今后的多位数和乘法竖式的教学打下基础。
教学中要注意引导学生去发现列竖式的方法，体会数位对齐的基本规律。
同时要求学生与加减法竖式进行比较，体会乘法竖式与加减法竖式的区别。
三、教学目标：1.知识与技能：学生掌握乘法竖式中各部分的名称，并理解各部分表示的意义。
2、过程与方法：使学生初步掌握乘法竖式的书写方法，能用竖式正确计算乘法。
3.情感态度与价值观：培养学生的计算能力。
四、教学重点：初步掌握乘法竖式的书写方法，能用竖式正确计算乘法。
五、教学难点：让学生理解积是两位数时的竖式书写格式。
六、教学过程：（一）复习导入1.用9的乘法口诀转盘的练习乘法口诀2.口算：（卡片出示）4×6 3×6 5×7 7×7 4×5 7×6 7×1 6×5（适当针对性问问学生是怎么算出来的）3.指名两位同学在黑板上用竖式计算，并口述计算过程和应注意什么。
36+23 59-16 4.创设情境，导入新课。
谈话：小朋友课余时间在图书室里看图书，你们看！每4人一组，这样的9组，图书管理员一共要发给他们多少本书呢？你能列出乘法算式算一算吗？（板书：4×9＝36）并说一说乘法算式各部分名称。
5.提出：加、减法可以用竖式计算，乘法也可以用竖式计算。
6.揭示课题：乘法竖式（二）探究新知教学： 1.教学4×9的乘法竖式你会列竖式计算4×9吗？试一试，指名板演。
（肯定板演正确的竖式，表扬写对的学生）说说乘法竖式各部分的名称。
（学生回答后，在竖式旁画出虚线标注。
）讨论：乘法竖式与加、减法竖式比一比，你发现了什么？你认为乘法竖式可以怎样写，怎样算？（用乘法口诀计算）2.讨论乘法竖式：重点解决以下问题：(1)乘法竖式的结构。
(2)算式中的4、9、36分别写在哪个数位上?为什么这样写?(引导学生利用加、减法竖式的经验去解决。
算式中4×9=36表示9个4是36，个位满十，所以要把3写在十位，6写在个位上。
)教师小结：乘法算式除了可以用口诀直接算积，还可以用竖式的方式进行计算，乘法竖式和加法、减法竖式的格式相同，只是计算符号不同，都要注意相同数位对齐。
乘法竖式计算时用乘法口诀计算。
3.试一试9×7。
尝试，出现计算的情况，板书：9 × 7 6 34.辨析：你认为哪一种写法是正确的？错误的问题在哪里？先跟同桌讨论，再全班交流。
63怎么算出来的？（用7的乘法口诀）9和谁对齐？3写在哪里？（这里结合孩子错误的例子进行正确的指导，注意反馈）指出：积的个位应与乘数的个位对齐。
5.小结：刚才我们学习了用竖式计算了乘法，提醒同学们注意用竖式计算乘法时要注意积的个位一定要和乘数的个位对齐，如果积满十时，积的十位要写在十位上。
（三）巩固练习1.第81页做做1。
让学生在书上独立完成，巡视时加强对书写不够规范的学生进行个别指导，并注意通过交流，使学生进一步明确积的个位要与乘数的个位对齐。
2.第81页做做2。
仔细审题，从题目中你都得到了那些信息，我们应该怎样列式？3.第83页第7题.先让学生填一填，再指名说说是怎样想的，用的是哪句口诀。
4.第83页第8题。
× 6 3 7 6 3 看图找信息，提问题，讨论解决。
要启发学生根据图中的信息先算“一共有多少间隔？” 让学生正确列式。
说一说，你是怎样想的？5.数学游戏：学生用数字卡片，同桌同学为一组，进行摆数算乘法算式。
6.背口诀比赛。
（四）全课总结板书：4×9=36（人）9 4 … 乘数9 ×9 … 乘数-----------------3 6 … 积 6 3笔算乘法×7=63×7第三篇：教学乘法竖式教学内容书本第64-65页例题、想想做做第1-4题。
共几课时1课型新授教学目标1.在具体情境中探索并初步掌握乘法的竖式写法，知道乘法竖式中各部分的名称，能用竖式计算表内乘法。
2.探索乘法竖式的过程中，进一步体会数学知识之间的内在联系，培养初步的抽象、概括以及合情推理能力。
3.培养学生积极的学习态度，树立学好数学的信心。
教学重难点重点：竖式的书写格式和计算过程。
难点：使学生明确积的个位应该和乘数对齐。
口算：16÷4 7×3 75+5 42-5 36÷6 7×4一、创设情景，导入新课1、谈话：每天中午我们班的小朋友都会在教室里阅读图书柜里的图书，你们看！（出示场景图）这里有2组同学在看书，每组4人，已经有多少人在看书？2、提问：你能列出乘法算式算一算吗？（指名回答，教师板书）3、指名说说乘法算式中各部分的名称。
4、提出：加减法可以用竖式计算，乘除法也可以用竖式计算。
（板书课题：乘法竖式）二、自主探索，感悟方法1、教学2×4的竖式（1）尝试列式，指名板演，肯定正确的竖式。
（1）提问：你能说说乘法算式中各部分的名称吗？（2）讨论：乘法竖式与加减法竖式比一比，你发现了什么？（3）引导学生讨论发现：乘法竖式与加减法竖式格式相同，计算符号不同，计算时用乘法口诀算。
2、试一试：5×7 先让学生独立计算选择板书如下 5 5 5 × 7 × 7× 7 3 5 3 5 3 5 辨析：你认为哪一种是正确的？同桌讨论，再在班里说说你想法。
