Alan学数学 – 九九乘法表

最近Alan很喜欢学乘法,自己出题自己做,然后让妈妈看结果对不对,虽然他的计算方法不是最好的,但自己尝试还是很值得鼓励的,数学锻炼的不仅仅是算数的能力,很多时候是训练的不同的思考方式,用不同的方法去解决问题,有的方法简单,有的方法比较笨,方法想得越多,思考的能力不断被开发,所以不要觉得孩子的方法笨而去批评,引导孩子想更多的办法来解答。

看着Alan这么想学习乘法,我用Excel做了个九九乘法表,贴在墙上,带着他们一起读。需要的可以点击九九乘法表下载。不喜欢这个版本,网上直接搜制作九九乘法表,有很多教程教你怎么做。

第一步,在Excel中的单元格A2-单元格A10依次输入1-9,单元格B1-单元格J1依次输入1-9

第二步,在单元格B2中输入一个公式,并将公式 “=B$1&”×”&$A2&”=”&B$1*$A2” 复制到其他空白单元格区域后完成乘法表。

付一首英文背乘法的儿歌:

2 times 1, 2 is the clue,
‘Cause with 2 times 1, the answer’s still 2.
2 times 2, the answer is double,
That makes 4, this double’s no trouble.

2 times 3, there are no tricks,
By mem-o-ry, the answer is 6.
Ask a friend, “what’s 2 times 4?”
He should answer 8, and no more.

2 times 5, pencil or pen,
You won’t need to erase if your answer is 10.
2 times 6 is time for the swings,
The answer’s 12, and the lunch bell rings.

2 times 7 is the name of the game,
14 is the answer, and there’s no-one to blame.
2 times 8 is an age that’s cool,
16 in years, and I’ll drive to school.

2 times 9 is an age that’s great,
18 in years, and I’ll graduate.
2 times 10 is good and plenty,
When you multiply, the answer is 20.
