| Commutative Property | ||
| #1 | 5 x 3 = 3 x a What is the value of a? | 5 |
| #2 | Jahmere said because he knows 6 x 4, he also know 4 x 6. Is he correct? Explain. |
Yes, he is correct. The commutative property says you can just turn the numbers around and get the same product. |
| #3 | 7 x 2 = 2 x a |
7 |
| #4 | What is another name for the Commutative Property? | Order Property/Turn Around Rule |
| #5 | Explain in writing what the commutative property is. | The Commutative Property says that you can change the order of your factors and still get the same product. |
| Associative Property | ||
| #1 | 6 x 7 = (6 x 2) + (6 x a) | 5 |
| #2 | Solve: (7 x 2 ) x 1 = | 14 |
| #3 | What is another name for the Associative Property? | Grouping Property |
| #4 | Edwin bought gum for his 3 friends. He bought 4 packages for each and the packages contained 5 pieces of gum. How much gum did Edwin buy? | 60 pieces of gum |
| #5 | Write two equations using the associative property and the factors 3, 4, 2 | (3 x4) x 2 4 x (3 x 2) (4 x 2) x 3 |
| Distributive Property | ||
| #1 | 3 x 20 = (3 x 10) = (3 x a) | 10 |
| #2 | Use the distributive property to solve: 4 x 8= | Examples: (2 x 8) + (2 x 8) or (4 x 5) + (4 x 3) |
| #3 | How can the distributive property help you solve "hard facts"? | You can use the distributive property to break the harder facts into two smaller easier facts, then solve. |
| #4 | Use the distributive property to find the product of 8 x 7= | Show the equations used to find 56 |
| #5 | Write an explanation of what the distributive property is. | You can break a larger fact into smaller facts, multiply then add . |
| Identity and Zero Property | ||
| #1 | What is the Identity Property of Multiplication? | The Identity property says that you can multiply by 1 and you are always going to get the other number. |
| #2 | What is the Zero Property of Multiplication? | The Zero Property says that the product of any number and zero is always zero. |
| #3 | 9 x 0 = a | 0 |
| #4 | 21 x 1 = | |
| #5 | Write equations using the zero property and identity property | Examples: 7 x 0 = 0 4 x 1 = 4 |
| Which Property Am I? | ||
| #1 | 13 x 1 = 13 | Identity Property |
| #2 | 8 x (2 x 2) = 32 | Associative Property |
| #3 | 50 x 0 = 50 | Zero Property |
| #4 | 8 x 7 = 7 x 8 | Commutative Property |
| #5 | 4 x 15 = (4 x 10) + (4 x 5) | Distributive Property |
| Final Question | |
| The Easter Bunny needs to hide 8 dozen eggs. Use the distributive property to determine how many eggs he needs to hide. | 8 x 12 = (8 x 2) + (8 x 10) = 16 +80 = 96 |
