Zero Property
When you multiply any number by zero, the product is ___________________
Examples:
Identity Property
When you multiply a number by 1, the product will always be that
_____________________________. The number keeps its own
_______________________________ —_______________________________________
Ex:
Commutative Property
In multiplication, if you change the __________________________________________,
the product ___________________
___________________________
Ex:
Associative Property
The associative property is also known as the _____________________________
property’.
You can ________________________________________________________ of the factors
and the product will be the same!
Ex:
That problem has _____________________________. Parenthesis tell us what
part of the problem to do _________________________.
__________________________________ do what’s in the parenthesis _______________.
Let’s Multiply 3 Factors
There are different ways that you can find the product of 3 x 4 x 2.
(3 x 4) x 2 –
You can
____________________________________________________ and get
3 x (4 x 2) –
This is the
________________________________________________
Guided Practice:
1
(4 x 5) x 1 =
4 x (5 x 1) =
2.
(2 x 6) x 2 =
2 x (6 x 2) =
3.
(5 x 2) x 2 =
5 x (2 x 2) =
Independent Practice
1.
3x3x4=
2.
2x5x8=
3.
3x3x3
Distributive Property
The _________________________________________ property says that multiplying
a number by a group of numbers added together, is the same as doing
each multiplication separately.
3 x 5 = 15
Guided Practice
1.
5 x 7 = 35
2.
3 x 13 = 39
Why would I want to use the distributive property?

Identify which property of multiplication is shown:
4x6x5–
4,589 x 0
9x6=6x9
14, 855 x 1 =
56 x 5 x 7
(56 x 5) x 7 =
56 x (5 x 7)
4 x 26 –
4 x 10 + 4 x 10 + 4 x 6
4x1=
