2
COMMUTATIVE PROPERTY: pumpkins bats

3
To commute means to travel… (like when people commute to work…or take a commuter train)

4
This does NOT work with subtraction (let’s see why)

5
This does NOT work with division either (let’s see why)

6
ASSOCIATIVE PROPERTY:

7
Who you associate with does not matter…. (the whole group is still the same)

8
This does NOT work with subtraction (let’s see why)

9
This does NOT work with division either (let’s see why)

10
IDENTITY PROPERTY:

11
The identity of the number stays the same…(just like if you put on a mask for Halloween, your identity stays the same…you are still the same person) SHOW ME YOUR I.D.

12
Let’s try to identify some math properties… GET YOUR RESPONSE CARDS READY

13
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 5 + 0 = 5

14
IDENTITY :)

15
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 3 + 4 = 4 + 3

16
COMMUTATIVE

17
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 9 x 5 = 5 x 9

18
COMMUTATIVE

19
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? (5+3)+2 = 5+(3+2)

20
ASSOCIATIVE

21
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 4 x 3 = 3 x 4

22
COMMUTATIVE

23
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? (3 x 8) x 6 = 3 x (8 x 6)

24
ASSOCIATIVE

25
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 5 x 4 = 4 x 5

26
COMMUTATIVE

27
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 7 x 1 = 7

28
IDENTITY. \____/

29
Now, let’s try it with letters…

30
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? a + b = b + a

31
COMMUTATIVE

32
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? a x 1 = a

33
IDENTITY

34
ASSOCIATIVE? COMMUTATIVE? or IDENTITY? a + (b + c) = (a + b) + c

35
ASSOCIATIVE

36
The associative property only works with… a)addition and multiplication b)addition and subtraction c)division and multiplication

37
The commutative property only works with… a)addition and subtraction b)division and multiplication c)addition and multiplication

38
The identity property only works with… a)addition and subtraction b)addition and multiplication c)division and multiplication

39
WHAT IS THE SAME FOR ALL 3 OF THESE PROPERTIES?

40
THEY ALL ONLY WORK FOR ADDITION AND MULTIPLICATION.

41
END OF SLIDE SHOW

42
Exit Slip ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 1. 4 + 3 = 3 + 4 2. 8 x 1 = 8 3. (3 + 1) + 7 = 3 + (1 + 7) Write in box: A C I NAME ______________________

43
FLASHBACK: ASSOCIATIVE? COMMUTATIVE? or IDENTITY? 1. 4 + 3 = 3 + 4 2. 8 x 1 = 8 3. 6 + 0 = 6 4. (3 + 1) + 7 = 3 + (1 + 7) 5. a + b = b + a write: A C I
