If you are multiplying five times and even number. Take half of
the number and put a zero after it. (The FIVES are half way through the 0 - 9 multiplication facts.
This helps you remember to take half of each number)
For example 5 x 6 (6 is even)
Take half of 6 (3)
Add a zero - 30
Another example 5 x 8
Take half of 8 (4)
Add a zero - 40
If you are multiplying 5 times an odd number, subtract 1 from the
number and halve the number. Then put a 5 after it.
For example 5 x 7 (7 is odd)
Subtract one from 7 (6)
Take half of 6 (3)
Add a five - 35
Another example 5 x 9
Subtract one from 9 (8)
Take half of 8 (4)
Add a five - 45
