Learning the Multiplication FactsPart 1
By Monica Yuskaitis
3 x 3 = 9 4 x 8 = 32
Multiplication Factsare easiest to learn when... You find patterns. You use rhymes. You use stories. You relate them to what
you already know.
Zero Pattern0 times any number is 0
0 x 3 = 0 0 x 7 = 0 0 x 4 = 0 0 x 1 = 0 0 x 0 = 0 0 x 9 = 0
What is
0 x 8 = 0
One’s Pattern1 times any number is the
same number 1 x 3 = 3 1 x 7 = 7 1 x 4 = 4 1 x 1 = 1 1 x 2 = 2 1 x 9 = 9
What is
1 x 5 = 5
Two’s Pattern2 times any number is that
number doubled 2 x 3 = 6 2 x 7 = 14 2 x 4 = 8 2 x 1 = 2 2 x 2 = 4 2 x 9 = 18
What is
2 x 5 = 10
Five’s Pattern - Step 1Cut the number you are
multiplying in half 5 x 3 = 1.5 5 x 7 = 3.5 5 x 8 = 4 5 x 1 = .5 5 x 2 = 1 5 x 6 = 3
Five’s Pattern - Step 2 If you are multiplying an odd
number, drop the decimal point 5 x 3 = 5 x 7 = 5 x 5 = 5 x 1 = 5 x 9 =
1. 53. 52. 5
. 54. 5
What is
5 x 7 = 3 5
What is
5 x 3 = 1 5
What is
5 x 9 = 4 5
What is
5 x 5 = 2 5
Five’s Pattern - Step 3 If you are multiplying an even
number, just add a zero 5 x 2 = 5 x 6 = 5 x 4 = 5 x 8 = 5 x 10 =
1 03 02 0
05 04
What is
5 x 8 = 4 0
What is
5 x 6 = 3 0
What is
5 x 4 = 2 0
What is
5 x 2 = 1 0
Nine’s Pattern - Step 1Subtract 1 from number you
are multiplying 9 x 3 = 2 9 x 7 = 6 9 x 8 = 7 9 x 1 = 0 9 x 2 = 1 9 x 6 = 5
Nine’s Pattern - Step 2Add a 2nd number that totals
nine with the 1st number 9 x 3 = 2 9 x 7 = 6 9 x 8 = 7 9 x 1 = 0 9 x 2 = 1 9 x 6 = 5

What is

What is
9 x 9 = 8 1
What is
9 x 6 = 5 4
What is
9 x 5 = 4 5
What is
9 x 3 = 2 7
What is
9 x 4 = 3 6
What is
9 x 2 = 1 8
Six’s Pattern (even #’s only)Step #1 Cut the number you
are multiplying in half.
6 x 2 = 1 6 x 4 = 2 6 x 6 = 3 6 x 8 = 4
Six’s Pattern (even #’s only)Step #2 The number you aremultiplying by 6 is the 2nd #.
6 x 2 = 1 6 x 4 = 2 6 x 6 = 3 6 x 8 = 4

What is
6 x 6 = 3 6
What is
6 x 2 = 1 2
What is
6 x 8 = 4 8
What is
6 x 4 = 2 4
