1. FOR OUR BBES 3 RD GRADERS MULTIPLICATION PROPERTIES

2. COMMUTATIVE PROPERTY Looks like… a X b = b X a The order of the numbers doesn’t change the answer to the problem!

3. COMMUTATIVE PROPERTY a X b = b X a How can I remember this? “Commutative” sounds like “communicate.” The a is COMMUNICATING (talking) with the b and then the b is COMMUNICATING (talking) back to the a.

4. COMMUTATIVE PROPERTY What goes in the blank? 5 X 2 = 2 X ___

5. COMMUTATIVE PROPERTY What goes in the blank? 5 X 2 = 2 X 5

6. COMMUTATIVE PROPERTY What goes in the blank? 7 X 8 = ___ X 7

7. COMMUTATIVE PROPERTY What goes in the blank? 7 X 8 = 8 X 7

8. ASSOCIATIVE PROPERTY Looks like… (a X b) x c = a X (b x c) The grouping of the factors doesn’t change the answer!

9. ASSOCIATIVE PROPERTY (a X b) x c = a X (b x c) How can I remember this? If you associate with someone, you are hanging out. So the a, b, and c all hang out or “associate” with each other but sometimes in different groups. (There is still only ONE a, b, and c hanging out! Just like there is only one Johnny, Freddie, and Bob!)

10. ASSOCIATIVE PROPERTY What goes in the blank? (2 X 3) x 7 = __ X (3 x 7)

11. ASSOCIATIVE PROPERTY What goes in the blank? (2 X 3) x 7 = 2 X (3 x 7)

12. ASSOCIATIVE PROPERTY What goes in the blank? (5 X 4) x 8 = 5 X (__ x 8)

13. ASSOCIATIVE PROPERTY What goes in the blank? (5 X 4) x 8 = 5 X ( 4 x 8)

14. DISTRIBUTIVE PROPERTY Looks like… a x (b + c) = (a x b) + (a x c) Multiplying the sum or difference by a number is the same as multiplying each number in the sum or difference by the number and adding or subtracting the product!

15. DISTRIBUTIVE PROPERTY a x (b + c) = (a x b) + (a x c) How can I remember this? If you distribute something, you hand it out. With this property, the first number is being distributed to the other numbers!

16. DISTRIBUTIVE PROPERTY What goes in the blank? 9 X (20 - 3) = (9 X ___) – (9 X 3)

17. DISTRIBUTIVE PROPERTY What goes in the blank? 9 X (20 - 3) = (9 X 20 ) – (9 X 3)

18. DISTRIBUTIVE PROPERTY What goes in the blank? 5 X (2 + 7) = (5 X 2) + (___ X 7)

19. DISTRIBUTIVE PROPERTY What goes in the blank? 5 X (2 + 7) = (5 X 2) + ( 5 X 7)

20. BONUS INFORMATION! MULTIPLICATION PROPERTIES

21. IDENTITY PROPERTY Looks like… a X 1 = a Any number multiplied by 1 will give you the original number!

22. IDENTITY PROPERTY a X 1 = a How can I remember this? A person has ONE identity which defines them. So any number multiplied by ONE would show the identity property!

23. IDENTITY PROPERTY What goes in the blank? 8 x 1 = ____

24. IDENTITY PROPERTY What goes in the blank? 8 x 1 = 8

25. IDENTITY PROPERTY What goes in the blank? ___ x 1 = 45

26. IDENTITY PROPERTY What goes in the blank? 45 x 1 = 45

27. ZERO PROPERTY Looks like… a X 0 = 0 When any number is multiplied with zero, the answer is zero!

28. ZERO PROPERTY a X 0 = 0 How can I remember this? Well… I hope this is as obvious to you as it is to me. Any number multiplied by ZERO equals ZERO in the ZERO property!

29. ZERO PROPERTY What goes in the blank? 5 x 0 = ____

30. ZERO PROPERTY What goes in the blank? 5 x 0 = 0

31. ZERO PROPERTY What goes in the blank? 2,346 x ____ = 0

32. ZERO PROPERTY What goes in the blank? 2,346 x 0 = 0
