The document discusses integer addition and cancellation. It provides examples of adding positive and negative integers where the numbers cancel each other out to equal zero. Students are shown number sentences and asked to demonstrate the answers using counters. The key ideas are that positive and negative numbers cancel each other out when added, and various addition problems with integers are worked through as examples.

1. AddingIntegers

2. Integers-1+1

3. IntegersWhat number does the picture below represent?-6

4. IntegersWhat number does the picture below represent?-9

5. IntegersWhat number does the picture below represent?+4

6. IntegersPositive and negative numbers cancel each other.0+1+ (-1) =

7. IntegersWhat will be the answer for this addition sentence?+5 + (-5) = 0

8. IntegersWhat will be the answer for this addition sentence?+3 + (-3) = 0

9. IntegersWhat is the number sentence demonstrated in the picture?What is the answer?0+4+ (-4)=

10. IntegersWhat is the number sentence demonstrated in the picture?What is the answer?-2+2+ (-4) =

11. IntegersWhat is the number sentence demonstrated in the picture?What is the answer?-1+5+ (-6) =

12. IntegersWhat is the number sentence demonstrated in the picture?What is the answer?+4-3+ (+7)=

13. IntegersWhat is the number sentence demonstrated in the picture?What is the answer?add-6-4+ (-2) =

14. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.-5+(+6) =or-5+ 6 =+1

15. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.-1-3+ 2 =

16. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.+6-4+(+10) =

17. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.+710 + (-3) =

18. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.-13-10 + (-3) =

19. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.+10+4 + (+6) =

20. IntegersAnd now try it yourself. When you see the number sentence, please arrange the counters on your desk, raise your hand and be ready to answer.0+5 + (-5) =
