Communication is back and forth between two people

Multiple Select

Put a check next to the equations that show the Commutative Property.

• 1+2=2+1

• 1+(2+3)=(1+3)+2

• 3∙4=4∙3

• 9 + 3 = 3 + 9

You can be grouped with different people (associates)

Multiple Select

Mark the equations that show the Associative Property.

• 7+(8+9)=(7+8)+9

• 3∙4=4∙3

• 6(x+3)=6x + 18

• 1∙(2∙3)=(1∙2)∙3

Multiple Select

Mark the equations that show the Distributive Property.

• 3(x−2)=3x−6

• 3(x+1)=3x+1

• −2(4x+1)=−8x−2

• 4∙(5−2)=4(5)−4(2)

Identity Property 

 $9+0=9$  

 $9\times1=9$

Identity is yourself

Multiple Select

Mark the equations that show the Identity Property.

• $\frac{10}{10}=1$

• $$10\bullet 1=10$$

• 10+0=10

• 10−10=0

Inverse Property

 $\frac{7}{8}\times\frac{8}{7}=1$  

-9 + 9 = 0

How will I remember?

Inverse means opposite OR upside down

Multiple Select

Mark the equations that show the Inverse Property.

• 1+(−1)=0

• −4+4=0

• $\frac{3}{4}\times\frac{3}{4}=1$

• $2\times\frac{1}{2}=1$
