Worksheet: Properties of Addition

In this worksheet, we will practice identifying the properties of addition we use when adding and use them to solve problems with numbers up to 20.

Q1:

What property is illustrated in the equation 9+0=9?

  • AIdentity property
  • BCommutative property
  • CAssociative property

Q2:

Pick the expression we get when we use the commutative property of addition with the expression 3+9.

  • A10+2
  • B6+6
  • C9+3
  • D4+8

Q3:

What property is illustrated in the equation (2+5)+9=2+(5+9)?

  • AAssociative property
  • BCommutative property
  • CIdentity property

Q4:

Which equation shows the commutative property of addition?

  • A4+7=7+4
  • B2+9=11
  • C(2+7)+9=2+(7+9)
  • D1+9=3+7

Q5:

What property is illustrated in the equation 2+7=7+2?

  • AIdentity property
  • BAssociative property
  • CCommutative property

Q6:

Fill in the blank: (2+7)+8=+(7+8).

Q7:

Which equation shows the associative property of addition?

  • A1+0=1
  • B1+1=1
  • C(1+6)+3=1+(6+3)
  • D1+6=6+1

Q8:

Pick the expression we get when we use the associative property of addition with the expression (1+5)+8.

  • A1+(5+8)
  • B5+8
  • C(8+5)+8
  • D1+8

Q9:

Which equation shows the identity property of addition?

  • A1+2=2+1
  • B1+1=1
  • C(1+2)+3=1+(2+3)
