<<show example – centered on screen>>
The associate property for addition or
multiplication deals with numbers being a
part of a group.
For example, when multiplying, we can
group 2 times 8 in this expression
(2 * 8)* 4
<<fade parentheses around 8 and 4 in
previous image. Reference below>>
2 * (8*4)
<<show example – centered on screen>>
(3 + 7) + 5
<<fade parentheses around 7 and 5 in
previous. Reference below>>
3 + (7 + 5)
<<show image – centered>>
or we can group 8 times 4.
Or, when adding, we can group 3 plus 7
or we can group 7 + 5
In this lesson, we are going to learn about
(2 * 3) * 4 = 2*(3*4)
the associative property of multiplication.

<Add the word “Parentheses” as an over
lay on a step in the image>
These steps are called the order of
operations.
They include doing parentheses first,
<Add the word “Exponents” as an over lay
on a step in the image>
<Add the words “Multiplication and
Division” as an over lay on a step in the
image>
<Add the word “Addition and Subtraction”
as an over lay on a step in the image>
then exponents,
multiplication and division in order from
left to right,
and then addition and subtraction in order
from left to right.

Question for Clip B
Stem:
What would you simplify first in the
expression 12 – 7 *3*(1+6)?
Answers for Question B
A. 12-7
B. 7*3
C. 3*(1+6)
D. 1+6
Correct Response  D
Using order of operations to simplify this
expression, we would multiply 6 times 1
because it is inside of parentheses.

is important, but being able to use them in
everyday life is even more important.

Use order of operations and simplify
multiplication first, since there are no
parentheses or exponents.

How can we use the commutative
property of multiplication to make this
expression easier to simplify?
<<show expression centered on previous
image>>
4 times 13 times 5
4* 13 * 5
<<background image fades leaving the
expression>>
4 * 13 * 5
<<make 4 and 5 much larger than 13 to
emphasize those numbers>>
Since it is easier to multiply 4 times 5
<<make 4 and 13 much larger than 5 to
emphasize those numbers>>
than 4 times 13,
<<Use a hand to drag and reorder 5 and
13>>
let’s reorder our numbers using the
commutative property of multiplication.
4 * 5 * 13
<<add to previous expression as shown
below>>
4*5*13 = 20*13 = 260
When we simplify completely, we get 260.

In math, to group terms together, we use
parentheses.

PEMDAS
Using Please Excuse My Dear Aunt Sally
We can simplify expressions with multiple
operations.
<<show example on screen – center>>
We will look for parentheses first.
5*(2 + 6)+22
<<highlight (2+6)>>
<<add example below previous>>
5 *8+ 22
<<highlight 22>>
Then, look for
<<show example below previous>>
5*8+4
Is there multiplication or division?
<<highlight 5*8>>
Do these operations in order from left to
right.
exponents
<<make an arrow and animate it going
from left to right of the expression>>
<<show example below – centered>>
40 + 4
Is there addition or subtraction?
<<highlight 40+4>>
Once again, do these in order from left to
right.
<<make an arrow and animate it going

<<add answer to original expression>>
5*(2 + 6)+22 = 40

Using order of operations, we are going to
do the multiplications in order from left to

or swap numbers
<<center title under previous and zoom to

using the commutative property of
multiplication
