Here's some tips for kids dealing with multiplication tables.

There is an important rule shown in the multiplication tables. Any number multiplied by 0 is equal to 0, and is not included in the multiplication table. Any number multiplied by 1 is itself.

Here are the multiplication tables for 1 through 12

1 x 1 = 1    2 x 1 = 2   3 x 1 = 3   4 x 1 = 4    5 x 1 = 5    6 x 1 = 6   7 x 1 = 7
1 x 2 = 2   2 x 2 = 4   3 x 2 = 6   4 x 2 = 8   5 x 2 = 10    6 x 2 = 12   7 x 2 = 14
1 x 3 = 3    2 x 3 = 6   3 x 3 = 9   4 x 3 = 12    5 x 3 = 15   6 x 3 = 18   7 x 3 = 21
1 x 4 = 4    2 x 4 = 8   3 x 4 = 12   4 x 4 = 16    5 x 4 = 20   6 x 4 = 24   7 x 4 = 28
1 x 5 = 5   2 x 5 = 10    3 x 5 = 15   4 x 5 = 20   5 x 5 = 25   6 x 5 = 30   7 x 5 = 35
1 x 6 = 6   2 x 6 = 12   3 x 6 = 18   4 x 6 = 24   5 x 6 = 30   6 x 6 = 36   7 x 6 = 42
1 x 7 = 7   2 x 7 = 14   3 x 7 = 21   4 x 7 = 28   5 x 7 = 35   6 x 7 = 42   7 x 7 = 49
1 x 8 = 8   2 x 8 = 16    3 x 8 = 24   4 x 8 = 32   5 x 8 = 40   6 x 8 = 48   7 x 8 = 56
1 x 9 = 9   2 x 9 = 18    3 x 9 = 27   4 x 9 = 36   5 x 9 = 45   6 x 9 = 54   7 x 9 = 63
1 x 10 = 10   2 x 10 = 20   3 x 10 = 30   4 x 10 = 40   5 x 10 = 50   6 x 10 = 60   7 x 10 = 70
1 x 11 = 11   2 x 11 = 22   3 x 11 = 33    4 x 11 = 44   5 x 11 = 55   6 x 11 = 66   7 x 11 = 77
1 x 12 = 12   2 x 12 = 24   3 x 12 = 36   4 x 12 = 48   5 x 12 = 60   6 x 12 = 72   7 x 12 = 84

8 x 1 = 8   9 x 1 = 9   10 x 1 = 10   11 x 1 = 11   12 x 1 = 12
8 x 2 = 16    9 x 2 = 18   10 x 2 = 20   11 x 2 = 22   12 x 2 = 24
8 x 3 = 24   9 x 3 = 27   10 x 3 = 30   11 x 3 = 33   12 x 3 = 36
8 x 4 = 32   9 x 4 = 36   10 x 4 = 40   11 x 4 = 44   12 x 4 = 48
8 x 5 = 40   9 x 5 = 45   10 x 5 = 50   11 x 5 = 55   12 x 5 = 60
8 x 6 = 48   9 x 6 = 54   10 x 6 = 60   11 x 6 = 66   12 x 6 = 72
8 x 7 = 56   9 x 7 = 63   10 x 7 = 70   11 x 7 = 77   12 x 7 = 84
8 x 8 = 64    9 x 8 = 72    10 x 8 = 80    11 x 8 = 88    12 x 8 = 96
8 x 9 = 72   9 x 9 = 81   10 x 9 = 90   11 x 9 = 99   12 x 9 = 108
8 x 10 = 80   9 x 10 = 90   10 x 10 = 100   11 x 10 = 110   12 x 10 = 120
8 x 11 = 88   9 x 11 = 99   10 x 11 = 110   11 x 11 = 121    12 x 11 = 132
8 x 12 = 96   9 x 12 = 108   10 x 12 = 120    11 x 12 = 132   12 x 12 = 144


There are a few things to notice when looking at the multiplication tables. Staring with the 1's, each answer goes up by 1. We say that the multiples of 1 are 1,2,3,4,5,6, and so on.

For the 2's tables, each answer goes up by 2. The multiples of 2 are 2,4,6,8,10,12, and so on.

For the 3's tables, each answer goes up by 3. The multiples of 3 are 3,6,9,12,15,18, and so on.

The same pattern is true for all the multiplication tables.

The answer to a multiplication problem is also called the product.

Notice that any number multiplied by 10 ends in 0.

It may seem hard to learn the whole table, but notice that 1 x 2 is the same as 2 x 1, 3 x 2 is the same as 2 x 3, and so on
