Transcript of "Adding integers"

  1. 1. Adding IntegersAll the information you need to successfullyadd positive and negative numbers.
  2. 2. First of all, What is an Integer?Integers are all of the whole numbers, and their opposites, including zero.(. . . -3, -2, -1, 0, 1, 2, 3, . . .)You can see the integers on the number line below. -5 -4 -3 -2 -1 0 1 2 3 4The arrows at the ends show that integers go forever in both direction.
  3. 3. Ok, so what isn’t an integer?Integers can’t be fractions or decimals, unlessthose fractions or decimals are equivalent to awhole number.For example: ⅖ or 1.25 can’t be written as wholenumbers, and are NOT integers.
  4. 4. Now, let’s learn how to perform the various calculations with integers. We will learn the rules for accurately adding, subtracting, multiplying and dividing integers.And sorry, thatdoesn’t mean you getto use a calculator.We get to use ourBRAINS instead!
  5. 5. Adding IntegersWe will take a look at a few ways to add integers.1. The number line model2. The chip model3. Using formal rulesIf you learn all three ways then you have different ways to attack a problem, and can choose which you like best.
  6. 6. Try these using the number line model
  7. 7. Here are the answers How’d you do?
  8. 8. Question timeHow did you like using the number line model?What about it made things easier or harder foryou?What part of the number line model did notmakes sense to you?Could you use this to solve addition problems ifyou had to?
  9. 9. Try these using the chip model
  10. 10. Here are the answers How did that go for you?
  11. 11. Question timeHow did you like using the chip model?What about it made things easier or harder foryou?What part of the chip model did not makes senseto you?Could you use this to solve addition problems ifyou had to?
  12. 12. Try These using the formal rules
  13. 13. Here are the answers Get’em all right?
  14. 14. Question timeHow did you like using the formal rules?What about it made things easier or harder foryou?What part of the formal rules did not makessense to you?Could you use these rules to solve additionproblems if you had to?
