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.
