Easy Sudoku

Sudoku数独游戏相信大部分家长都知道怎么玩,这里就不解释了,有问题请问google。

小朋友可以从简单的4X4开始。下面会附上三页作为例子,也可以到

最开始的时候小朋友还不太熟悉规则,家长可以帮助检查,但是熟悉了以后,尽量鼓励小朋友自己检查。 尤其是最后做完以后check整个表 , 一定要鼓励小朋友自己先检查一遍是不是都对了,是不是每行每竖每个粗方框里每个数字只出现一遍.

如果有不确定是哪个数字的时候,可以用Guess and Check 的方法,这时候也是尽量鼓励和引导小朋友自己Check。

手机/iPad上也有很多app,不过我还是比较推荐在纸上做,这样可以自己检查,app里经常是它帮助你检查对不对。

下面是4张简单的,答案在第二页

下面是难一点的4×4的:

下面是简单的9×9的:

English Nine Nine Multiplication Table

Here is the Chinese Nine Nine Multiplication Table in English, that is, 9 times table.

我以前教老二背乘法表的时候,网上没有找到满意的版本。所以我做了两个九九乘法表的英文版,给大家分享一下。你也可以在下面打印PDF版。我最重要的经验是,千万不要像skip counting一样只记答案。 因为那样几天下来小朋友可能还是搞不清7×6是什么。

背乘法表的时候,小朋友可以横着背:
One one is one
One two is two
Two two is four
One three is three
Two three is six
Three three is nine
。。。

也可以竖着背:
One one is one
One two is two
One three is three
One four is four
One five is five
One six is six
One seven is seven
One eight is eight
One nine is nine
Two two is four
Two three is six
Two four is eight
Two five is ten
Two six twelve
Two seven fourteen
Two eight sixteen
Two nine eighteen
。。。

需要指出来的是乘法满足交换率(Commutative property),所以小朋友只需要背会乘法表的下三角就行了,比如只要记住Two Nine Eighteen,而不需要专门记忆Nine Two Eighteen。
