  • Multiplication: An operation that gives the totalnumber when you join equalgroups.

    Example: 4 + 4 + 4 + 4 = 16 or 4 x 4 = 16

  • Factors: Numbers that are multiplied to give a product.

    Example: 3 x 2 = 6 (3 and 2 are factors)

  • Product: The answer to a multiplicationproblem.

    Example: 5 x 2 = 10 (10 is the product)

  • You find patterns.

    Example: 2 x 7 = 14 can be found by counting by twos 2, 4, 6, 8, 10, 12, 14

  • You use rhymes.

How to multiply by zero 0
How to multiply by zero (0)

  • Rule: Any number times zero is alwayszero!

    Zero Times Table

  • 0 x 0 = 0

  • 0 x 1 = 0 1 x 0 = 0

  • 0 x 2 = 0 2 x 0 = 0

  • 0 x 3 = 0 3 x 0 = 0

  • 0 x 4 = 0 4 x 0 = 0

  • 0 x 5 = 0 5 x 0 = 0

  • 0 x 6 = 0 6 x 0 = 0

  • 0 x 2 365 778 = 0


Now let s practice the zero times tables get your pencil ready and answer the following questions

0 x 7 =

3 x 0 =

5 x 0 =

0 x 9 =

0 x 6 =

How to multiply by one 1
HOW TO MULTIPLY BY ONE (1)

  • Rule: One times any number is the samenumber

  • Groups: There is only one group

    Example: 1 x 5 = 5, one group of 5 is 5

  • Arrays: 3 rows of 1 is 3 1 row of 3 is 3

    Example: 3 x 1 = 3 1 x 3 = 3


Now let s practice the one times tables get your pencil ready and answer the following questions

5 x 1 =

3 x 1 =

1 x 1 =

1 x 7 =

1 x 0 =

12 x 1 =
