Multiplication Factsare easiest to learn when...: 

Multiplication Facts are 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: 

Zero Pattern 0 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: 

What is 0 x 8 = 0

One’s Pattern1 times any number is the same number: 

One’s Pattern 1 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: 

What is 1 x 5 = 5

Two’s Pattern2 times any number is thatnumber doubled: 

Two’s Pattern 2 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:
