BASIC ADDITION REVIEW

1. 7 + 6 = __________2. 8 + 5= __________3. 4 + 9= __________4. 9 + 7= __________5. 6+ 3+ 4= __________

THE NUMBERS THAT WE ADD ARE CALLED ADDENDS. EX. 7 + 3

THE ANSWER IN ADDITION IS CALLED SUM. 7 + 3 = 10

IN ADDITION, IT IS GOOD TO THINK IN TERMS OF TENS IF WE WANT TO ADD

FASTER.

EXAMPLE: 8 + 3 + 2 =

SO WE SAY WE CAN ADD 8 + 2 FIRST TO GIVE YOU TEN AND ADD 3 TO MAKE IT

13

WHAT WILL YOU ADD TO THE FOLLOWING NUMBERS TO GET 10?

1. 5 + ____ = 10 2 + ______ = 102. 7 + ____ = 10 0 + ______ = 103. 1 + ____ = 10 8 + ______ = 104. 4 + ____ = 105. 6 + _____ = 10

ADD THE FOLLOWING . LOOK FOR TENS TO MAKE YOUR WORK FASTER.

1. 8 + 6 + 2= 4. 7 + 5 + 5 =2. 7 + 3 + 8= 5. 6 + 4 + 2=3. 4 + 5 + 6= 6. 2 + 9 + 8=

What number will I add to 4 to get 4?

What number wil I add to 18 to 18 ?

CHANGING THE ORDER OF THE ADDENDS DOES NOT CHANGE THE SUM . THIS IS

CALLED ___________ PROPERTY OF ADDITION.

4 + 5 = 9 6 + 7 = 13 9 + 2 = 11

5 + 4 = 9 7 + 6 = 13 2 + 9 = 11

CAN YOU GIVE OTHER EXAMPLES?

Give the missing number in each exercise. Write your answer on the blank.

1. 7+0= _____2. 0+10=_______3. ____+0= 154. 0+ _____= 175. 19 +_____ = 196._____+ 16 = 167. 0 + _____= 208. 15 + 0 = ________9. 19+ _____= 1910.5+0 = ______


4/10

Fill in the blanks with the correct number.

1. 8 + 9 = _____ 2. ___ + 7 = 13 3. 5 + ____ = 119 + ___= 17 ___ + 6 = 13 6 + 5 = ____

4. 3 + 9 = ______ 5. 6 + _____ = 10 _____+ ______ = 12 4 + _____ = 10

The _________ property of addition means that the grouping of the

addends does not change the sum.

2 + 6 + 8 = 16

2 + ( 6 + 8 ) = 16

2 + 14 = 16

(2+ 6 ) + 8 = 16

8 + 8 = 16

(2+ 8 ) + 6 = 16

10 + 6 = 16

Fill in the blanks with the missing numbers.

1. 4 + 6 + 5 = _____ 9 + 6 +4 = ________(4 + 4) + 5 = ______ (9 + ___) + 4 = 19

_____+ 5 = 15 ______ + 4 = 19

4 + ( 6+ 5 ) = _____ 9 + ( 6 + 4 ) = _____

4 + ____= 15 9 + ___ = 19

Show the grouping property to answer the following:

1. (6 + 4 ) + 7 = ______ +7 = ______6 + (4 + 7) = 6+___= _______

2. (3 + 8 ) + 2 = _____+ 2 = ________3 + ( 8 + 2)= 3 + ___= _______

3. (10 + 6) 4= _____ + 4 = ________10 + ( 6 + 4) = 10 + ____ = _______

Rearrange the addends as you wish. Find the answers.
