二年级1-6乘法口算
二年级口算题乘除

二年级口算题乘除二年级乘除法口算题(人教版)一、乘法口算题(10题)1. 3×2 =- 解析:这是一道简单的乘法运算,表示2个3相加,即3 + 3=6,所以3×2 = 6。
2. 4×5 =- 解析:表示5个4相加,4+4 + 4+4+4 = 20,所以4×5 = 20。
3. 2×6 =- 解析:6个2相加,2+2+2+2+2+2 = 12,所以2×6 = 12。
4. 7×1 =- 解析:任何数乘以1都等于它本身,所以7×1 = 7。
5. 5×3 =- 解析:3个5相加,5 + 5+5=15,所以5×3 = 15。
6. 8×2 =- 解析:2个8相加,8+8 = 16,所以8×2 = 16。
7. 3×9 =- 解析:9个3相加,3+3+3+3+3+3+3+3+3 = 27,所以3×9 = 27。
8. 6×4 =- 解析:4个6相加,6+6+6+6 = 24,所以6×4 = 24。
9. 2×7 =- 解析:7个2相加,2+2+2+2+2+2+2 = 14,所以2×7 = 14。
10. 5×8 =- 解析:8个5相加,5+5+5+5+5+5+5+5 = 40,所以5×8 = 40。
二、除法口算题(10题)1. 10÷2 =- 解析:除法是乘法的逆运算,2×5 = 10,所以10÷2 = 5,表示把10平均分成2份,每份是5。
2. 18÷3 =- 解析:因为3×6 = 18,所以18÷3 = 6,也就是18里面有6个3。
3. 24÷4 =- 解析:由于4×6 = 24,所以24÷4 = 6,即把24平均分成4份,每份是6。

4 用1~6的乘法口诀求商 说课稿-2021-2022学年数学二年级上册(苏教版)

4 用1~6的乘法口诀求商一、教学目标通过本节课的学习,学生将能够:•掌握1-6的乘法口诀并能够熟练运用;•能够用1-6的乘法口诀来求商。
二、教学重点•让学生掌握1-6的乘法口诀;•教学生如何用1-6的乘法口诀求商。
三、教学难点•如何教会学生用1-6的乘法口诀来求商。
四、教学方法•讲解法:讲解口诀,带着学生练习;•互动问答法:通过提问来检查学生掌握情况;•练习法:通过习题来巩固所学知识。
五、教学过程1. 导入新课教师将卡片准备好,让学生依次快速读出题目上的乘法口诀。
2. 温故而知新推出每个数对应的乘法口诀,并让学生边读口诀,边对应着点数做计算。
比如:•1乘法口诀:任何数和1相乘,都等于它本身;•2乘法口诀:将这个数加上这个数,就得到了这个数的2倍;•3乘法口诀:先将一个这个数的2倍求出来,再将它加上这个数本身就是这个数的3倍了;•4乘法口诀:先将这个数的2倍求出来,再将它的2倍再求出来,所得到的数就是这个数的4倍;•5乘法口诀:取那个数的一半,然后加上这个数的一半,就是这个数的5倍;•6乘法口诀:先将这个数的5倍求出来,再将这个数的2倍求出来,将这两个数加起来得到的结果就是这个数的6倍了。
3. 导入教学重点将难点部分进行解释,让学生感知1-6的乘法口诀的应用。
当做除法时,应该采取怎样的方式计算。
4. 案例演示举例展示一些用1-6的乘法口诀进行除法计算的例子。
比如:28除以4等于几?由乘法口诀4乘以7=28 可以知道。
换句话说,28除以4就等于7。
再比如,18除以2等于几?由乘法口诀2乘以9=18 可以知道。
换句话说,18除以2就等于9。
5. 练习验证带领学生进行练习巩固所学的知识。
比如,让学生计算30除以5的商是多少呢?由乘法口诀5乘以6=30 得知,30除以5的商是6。
6. 总结体会与小结学生观看口算视频教学,参与班级贴吧交流,以巩固所学内容。
六、教学评价•通过观察学生的练习情况,评价学生是否掌握1-6的乘法口诀;•通过测试或问答来检查学生的掌握情况;•对于学生在求商过程中出现的错误进行指导和纠正。
