Kids Math: Multiplications

Date:  Sep 14, 2013

I made this for Jay Jay.  And I told him, memorising multiplication is very easy.  You only need to memorise the colour one.  

Jay: Huh?  We need to learn ONLY 9×9=81 for 9 multiplication?  

Dad:  Yes!  You have learn 9×8, 9×7, etc before.  

Jay: Huh?  Puzzled.

Dad:  9×8 is 8×9, 9×7 is 7×9, so, you learned those in 8 multiplication table, so no need to learn twice.

Jay: Oh really. Ya!  

Dad:  So, you do not need to learn twice.

Jay:  Happy.

Of course, I have another one that has the answer on it.

You can do this using Excel.  And then print it out.

So, every morning, let him take a look at the table and try to memorise.

I sent him to CMA class.  And there is a nice little multiplication songs that he has to learned since few weeks ago.

So, here he bring up his iPod to learn the song.  The challenge is when you use a song, he has to sing the song from 9×1, 9×2 to 9×8 to get the answer of 9×8.  HaHaHaHa.  But that is the easiest way to do it.

After that, let’s put this on test.  Give him some assessment book.  And when he can do all these, then, it is OK.

Make it a fun thing for him to learn.

I caught him “trying” to read my book one day.

And the next thing you know, he has mastered the multiplication of 11 with any two digit number.

Dad: 43 x 11 =?

Jay:  473 (1 second calculate in his head)

Dad:  54 x 11 =?

Jay:  594

Dad:  how about 65 x 11 =?

Jay:  (he took 4 seconds) 615, no 715.

Yes, if you add up the two numbers is more than 10, you need carry over the 10 to the first digit.  So, you add 1 to 6.
