Georgia Performance Standards

STANDARD:M3N2 Students will further develop their skills of addition and subtraction and apply them problem solving.

ELEMENT: a: The students will use the properties of addition and subtraction to compute and verify the results of computation.

ADDITION VOCABULARY

ADDITIONJoining two or more addends together.

6+3=9

is an addition sentence

ADDEND

The numbers you are adding together to find a sum.

Which numbers are the addends?

6 +3=9Yes, 6 and 3 are the addends!

SUMThe answer to an addition problem.

Which number is the sum?

6 +3=9

Yes, 9 is the sum!

Inverse Operations

Operations that undo each other.Addition and Subtraction are

inverse operations

6 + 3 = 9 9 – 3 = 6

2+6=8 8-6=23+7=10 10-7=34+1=5 5-1=49+8=17 17-8=9

5+10=15 15-10=5

Are all examples of inverse operations.

ADDITIONPROPERTIES

Identity Property

Any number plus zero equals that same number.

6 + 0 = 6 24 + 0 = 24

Commutative Property of

Addition

When you add two numbers in any order you reach the same sum.

6+3=9 & 3+6=9

Associative Property of

Addition

When you add three or more addends in different ways, the sum stays the same.

6+3+4=13 3+4+6=13 4+6+3=13 6+4+3=13 3+6+4=13 4+3+6=13

It does not matter what

order you put the addends 3,4 and

6… Their sum will always be

13.
