  1. ADDITION VOCABULARY and PROPERTIES T. GOODSON JME

  2. Georgia Performance StandardsSTANDARD: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.

  3. ADDITION VOCABULARY

  4. ADDITION Joining two or more addendstogether.

  5. 6+3=9is an addition sentence

  6. ADDEND The numbers you are adding together to find a sum.

  7. Which numbers are the addends? 6 3 9 + = Yes, 6 and 3 are the addends!

  8. SUM The answer to an addition problem.

  9. Which number is the sum? 6 3 9 + = Yes, 9 is the sum!

  10. Inverse Operations Operations that undo each other. Addition and Subtraction are inverse operations 6 + 3 = 9 9 – 3 = 6

  11. 2+6=8 8-6=23+7=10 10-7=34+1=5 5-1=49+8=17 17-8=95+10=15 15-10=5Are all examples of inverse operations.

  12. ADDITIONPROPERTIES

  13. Identity Property Any number plus zero equals that same number. 6 + 0 = 6 24 + 0 = 24

  14. Commutative Property of Addition When you add two numbers in any order you reach the same sum. 6+3=9 & 3+6=9

  15. 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

  16. It does not matter what order you put the addends 3,4 and 6… Their sum will always be 13.

  17. Which property is this an example of?3+0=3 A. commutative B. associative C. identity D. inverse operation

  18. What is this an example of?4+5=9 9-5=4 A. commutative B. associative C. identity D. inverse operation

  19. Which property is this an example of?6+8=14 8+6=14 A. commutative B. associative C. identity D. inverse operation

  20. Which property is this an example of?1+3+5+7=16 3+7+5+1=16 A. commutative B. associative C. identity D. inverse operation

  21. GREAT JOB!!!
