### The Properties of Multiplication:

The Properties of Multiplication Elizabeth Hill Third Grade

### Can you match the multiplication facts to the pictures?:

Can you match the multiplication facts to the pictures? 5x3= 4x3= 3x8= 4x7=

### What are we learning?:

What are we learning? The State of Georgia says M3N3e Students will apply the identity, commutative and associative properties of multiplication and verify the results.

### In Kid Terms:

In Kid Terms I understand and can use the properties of multiplication.

### Slide 5:

The Properties of Multiplication The Properties are the rules of multiplication and make problems easier. 1. Commutative Property – It doesn’t matter what order you multiply 2 numbers the answer is always the same. Ex: 2x3=3x2 2. Associative Property – When you multiply 3 or more numbers together, it doesn’t matter how you group them. The answer will be the same. Ex:(4x7)x6=4x(7x6) 3. Identity Property – When multiplying a number by 1, the answer will always be that number. Ex: 7x1=7

### Commutative Property:

Commutative Property Get out your manipulative box. Open the box and get out the colored squares. Close the box and put it away. Let’s get ready to build some arrays.

### Commutative Property:

Commutative Property Make an array to represent 2x6 2 rows of 6 Can you show the same problem a different way? So we can say that 2x6=6x2 6 rows of 2

### Commutative Property:

Commutative Property Make an array to represent 3x5 3 rows of 5 Can you show the same problem a different way? So we can say that 3x5=5x3 5 rows of 3

### Commutative Property:

Commutative Property Make an array to represent 3x4 3 rows of 4 Can you show the same problem a different way? So we can say that 3x4=4x3 4 rows of 3

### Make 2 arrays that show the Commutative Property:

Make 2 arrays that show the Commutative Property Your Turn! When your finished, raise your hand to show me and get some practice.

Associative Property – When you multiply 3 or more numbers together, it doesn’t matter how you group them. The answer will be the same. Ex:(4x7)x6=4x(7x6) 3. Identity Property – When multiplying a number by 1, the answer will always be that number. Ex: 7x1=7

### Associative Property:

Associative Property When I think about the associative property, I think about the Jonas Brothers. The 3 of them are always together. When you see 2 of them together, the other is somewhere near. + + No matter which 2 you see first, you will still have the Jonas Brothers. =

### Associative Property:

Associative Property (2x3)x5= 2x 3x5 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated?

### Associative Property:

Associative Property (6x8)x2= 6x 8x2 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated?

### Associative Property:

Associative Property 1x(9x4)= 1x9 x4 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated?

### Associative Property:

Associative Property 5x(2x6)= 5x2 x6 What are the numbers you should write on the other side? Where should the parentheses go to show what to associate? ( ) What 2 numbers are being associated?

### Slide 27:

The Properties of Multiplication The Properties are the rules of multiplication and make problems easier. 1. Commutative Property – It doesn’t matter what order you multiply 2 numbers the answer is always the same. Ex: 2x3=3x2 2. Associative Property – When you multiply 3 or more numbers together, it doesn’t matter how you group them. The answer will be the same. Ex:(4x7)x6=4x(7x6) 3. Identity Property – When multiplying a number by 1, the answer will always be that number. Ex: 7x1=7

### Identity:

Identity Your identity is who you are. Who you are doesn’t change. You are always you. No matter how you change (clothes, hair, size), you are always you.

### Identity:

Identity Peter Parker puts on a costume & becomes Spiderman. But underneath the Spidey suit, he is still Peter Parker. His identity did not change.

### Identity:

Identity Miley Cyrus puts on a wig & becomes Hannah Montana. But underneath the blonde wig, she is still Miley Cyrus. Her identity did not change.

### Identity Property:

Identity Property The identity property is the rule of what makes a number stay the same or keep its identity. Identity Property of Addition What number do you add to 5 to make it stay 5? 0 5+0=5 When you add 0 to 5, 5 keeps its identity.

### Identity Property:

Identity Property Identity Property of Multiplication What number do you multiply by 5 to make it stay 5? 1 5x1=5 When you 1 by 5, 5 keeps its identity.

### Identity Property:

Identity Property Identity Property of Multiplication What number do you multiply by 8 to make it stay 8? 1 8x1=8 When you 1 by 8, 8 keeps its identity.

### Slide 34:

What are some other examples?

### Slide 35:

Work with your partner to write 10 other examples of the identity property of multiplication. Get creative!

### Proper Multiplication Properties:

Proper Multiplication Properties 1. Create a book about the properties of multiplication. 2. On cover, write title for book and your name. 3. First page should be about the commutative. Tell what it is and give 3 examples. 4. On the next page show the associative. On the next show identity. Make sure there is a definition and 3 examples for each. 5. It must be checked and approved before you can use crayons.
