1 Adding and Subtracting Whole Numbers and Money Fact Families

2 Properties Commutative Property of Addition 3 + 5 = 5 + 3 Identify Property of Addition 5 + 0 = 5

3 Vocabulary Addends Sum Difference Subtrahend minuend

4 Add 345 + 67 $1.25 + $12.50 + $5

5 Subtract 345 – 67 Jim spent $1.25 for a hamburger. He paid for it with a five-dollar bill. Find how much he should get back by subtracting $1.25 from $5.

6 Fact Families 4,5, and 9 are a fact family.

7 Rearrange the numbers in this addition fact to form another addition and two subtraction facts. 11 + 14 = 25

8 Rearrange the numbers in this subtraction fact to form another subtraction fact and two addition facts.

9 White Boards a.3675 + 426 + 1357 b.$6.25 + $8.23 + $12 c.5374 – 168 d.$5 - $1.35 e.Arrange the numbers in this subtraction fact to form another subtraction fact and two addition facts. 25 – 10 = 15
