Objective: Today you will be able to… use the commutative and associative
properties of addition and multiplication.
Proving Behavior: By… coming up with your own examples that
demonstrate the 2 properties.
Purpose: We are doing this because… both properties are essential to
solving problems that you’ll face in the future.

“Say”s are appropriate teacher directed statements that further student learning
“See”s are appropriate think alouds, steps in the VIP, modeling, visual examples that further student learning, and varied
“Do”s are appropriate student actions that match the Say and the See and are varied
Step 1
Define Commutative
Property
Say: The commutative property includes the word “commute.” Commute means to move or to change; think of the word “commuters.”
Have you guys ever heard that word before? Like someone who commutes work?
See: Arrows demonstrating that commute means to move/swap places
* Do: Choral Response: What does to “commute” mean?
Step 2
Say: So the commutative property applies to both addition and multiplication but doesn’t apply to subtraction and division. Let’s focus
Demonstrate
Commutative
Property of Addition
Step 3
Commutative
Property of
Addition: People
example
on the commutative property of addition. When we add two numbers together, we can change/swap their order—that is, commute
their order—without changing the resulting sum.
See: 3 + 2 = 5 and 2 + 3 = 5; therefore 3 + 2 = 2 + 3; that is, 5 = 5
* Do: Now create your own example of the commutative property of addition and write it how I wrote 3 + 2 = 2 + 3. Write it on your
whiteboard and raise it so I can see it when you’re done.
Say: OK, now I want you guys to demonstrate this property. Everyone pair up and stand immediately next to your partner. Now take
one step apart. Imagine there is a plus sign between you two. You two together equal one combination; a sum. Now switch sides.
You’re now in a different order, but added together you’re the same combination.
See: Teacher demonstrates with one student.
* Do: Students participate in exercise.
Step 4
Variables
Say: As we’ve seen, for example, 3 + 2 = 2 + 3 and you gave me your examples. Numbers can be represented by letters. These are called
variables We can write a + b = b + a. “a” can represent any number but “a” represents the same number in the equation; the same holds
for “b.” So all the a’s represent the same number and all the b’s represent the same number.
See: a + b = b + a
* Do: Choose 2 letters not a and b and write them in the form of the commutative property of addition on your whiteboard and hold up.
Step 5
Commutative
Property of
Multiplication
Say: Like with addition, there is a commutative property of multiplication. When we multiply numbers together, we can change their
order without changing the resulting product.
See: 4*2 = 8 and 2*4 = 8; therefore 4*2 = 2*4; that is 8 = 8
* Do: Now create your own example of the commutative property of multiplication and write it how I wrote my example. Write it on
your whiteboard and raise it so I can see it when you’re done.
Step 6
Commutative
Property of
Multiplication
Say: Like I said with addition, the multiplication version of this property can be represented with variables. The variables represent
any possible numbers (Use shapes if they struggle with the concept).
See: a*b = b*a
* Do: Choose 2 letters not a and b and write them in the form of the commutative property of multiplication on your whiteboard and
hold them up.
Say: The associative property of addition includes the word to associate. “Associate” means to group/be with someone else or
something. A person, for example, associates—that is, groups himself with—certain other persons. The same thing holds for numbers.
When we throw parentheses around numbers that we are adding, we are associating—grouping—them together. That means, if we
recall order of operations from yesterday and from our “do now,” we take care of whatever is in the parentheses first. The trick here,
however, is that no matter where you put your parentheses, you get the same sum. This is the associative property of addition.
See: (2 + 3) + 5 = 2 + (3 + 5)
(5) + 5 = 2 + (8)
10 = 10
Do: Create your own example of this property, writing it on your whiteboard and holding it up for me to see.
Step 7
Associative Property
of Addition
Step 8
Associative Property
of Addition:
Variables
Step 9
Associative Property
of Multiplication
Step 10
Associative Property
of Multiplication:
Variables
Say: As we have already established, we can use letters to represent numbers. Every place we had numbers in our previous example,
we can use letters. The letters just represent any possible number but each letter represents the same number in any given equation.
See: (a + b) + c = a + (b + c)
Do: Use your own letters to write out this property with variables. Show your whiteboard when you’re done.
Say: When we multiply three or more numbers together, again it doesn’t matter where we throw down our parentheses—we will get
the same product. This is the associative property of multiplication. So, again remembering our good practice from yesterday, we will
do what’s in the parentheses first, but it really doesn’t matter.
See: (4*2)*2 = 4*(2*2)
8*2 = 4*4
16 = 16
Do: Create your own example of this property, writing it on your whiteboard and holding it up for me to see.
Say: Again, we can use variables to represent numbers.
See: (a*b)*c = a*(b*c)
Do: Create your own example, using your own letters. Hold it up for me to see.

students approach automaticity by manipulating, time, materials, group size)

Example 1: 5*7 = 7*5: Write down which property is illustrated in this example.
Example 2: Write an example of the associative property of addition
Example 3: 6 * 3 * 2 = 6 * 3 * 2
Write in parentheses where appropriate to demonstrate the associative property of multiplication.
Example 4: 3 + 4 = 4 + ______ . Fill in the correct number to demonstrate the commutative property of addition.
