Multiplication Facts and Hints
Every multiplication has a twin, which may be easier to remember.
For example if you forget 8×5, you might remember 5×8. This way, you only have to remember half the table.
to multiply by 
Trick 

2

add the number to itself (example 2×9 = 9+9) 
5

the last digit goes 5, 0, 5, 0, ... 
is always half of 10× (Example: 5x6 = half of 10x6 = half of 60 = 30)  
is half the number times 10 (Example: 5x6 = 10x3 = 30)  
6

when you multiply 6 by an even number, they both end in the same digit. Example: 6×2=12, 6×4=24, 6×6=36, etc 
9

the last digit goes 9, 8, 7, 6, ... 
is 10× the number minus the number. Example: 9×6 = 10×6−6 = 60−6 = 54  
when you add the answer's digits together, you get 9.
When learning the 9 times table, remember that the number in the 10s column will be one less than the number they are multiplying 9 by. For example, 8 x 9 will have a 7 in the tens column as it is 1 less than the 8 and the answer is a number bond to 9. Therefore 8 x 9 is 72 because 7 + 2 = 9. 

10

put a zero after it 
11

up to 9x11: just repeat the digit (Example: 4x11 = 44) 
for 10x11 to 18x11: write the sum of the digits between the digits Example: 15x11 = 1(1+5)5 = 165 Note: this works for any twodigit number, but when the sum of the digits is more than 9, we need to"carry the one". Example: 75x11 = 7(7+5)5 = 7(12)5 = 825. 

12

is 10× plus 2× 
This may not work for you, but it worked for me. I like remembering the squares (where you multiply a number by itself):
1×1=1  2×2=4  3×3=9  4×4=16  5×5=25  6×6=36 
7×7=49  8×8=64  9×9=81  10×10=100  11×11=121  12×12=144 
And this gives us one more trick. When the numbers we are multiplying are separated by 2 (example 7 and 5), then multiply the number in the middle by itself and subtract one. See this:
5×5 = 25 is just one bigger than 6×4 = 24 
6×6 = 36 is just one bigger than 7×5 = 35 
7×7 = 49 is just one bigger than 8×6 = 48 
8×8 = 64 is just one bigger than 9×7 = 63 
etc ...
