Hi there -

I've made up a table for you that goes through 12x12 - I hope that's 
enough.

         2    3    4    5    6    7    8    9   10   11   12

    2    4    6    8   10   12   14   16   18   20   22   24

    3    6    9   12   15   18   21   24   27   30   33   36
    
    4    8   12   16   20   24   28   32   36   40   44   48
    
    5   10   15   20   25   30   35   40   45   50   55   60
    
    6   12   18   24   30   36   42   48   54   60   66   72

    7   14   21   28   35   42   49   56   63   70   77   84
   
    8   16   24   32   40   48   56   64   72   80   88   96
    
    9   18   36   36   45   54   63   72   81   90   99  108

   10   20   30   40   50   60   70   80   90  100  110  120

   11   22   33   44   55   66   77   88   99  110  121  132

   12   24   36   48   60   72   84   96  108  120  132


Do you notice any patterns?  How about in the 2's column?  

Look at the horizontal and vertical rows for the 10's and the 11's - 
they're pretty easy to see.

Have you seen our archive of questions and answers for Dr. Math? (The 
URL is at the bottom of this message.) There's a suggestion for 
learning multiplication tables that you should really look at there:

My grandfather was one of the first surveyors of the Mississippi 
River.  He was an engineer and floated down the river on a raft.  I've 
been told that he was famous for playing the harmonica and knowing his 
multiplication tables through 20x20.  When you have learned your 
tables through the 12's, you'll probably be able to make up a table 
for the higher numbers yourself!

I think the only real way to learn your multiplication tables is to 
practice a lot.  They are a really good thing to know, though - you 
will use them all the time, even when you're grown up!
