### Integer Review!

1. 1. Integer Review!
2. 2. What do we know about integers? <ul><li>Integers are the whole numbers and their opposites </li></ul><ul><li>Two integers are opposites if they are the same distance from 0 in either the positive or negative direction on a number line </li></ul><ul><li>Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, … </li></ul><ul><li>Negative numbers are less than zero. </li></ul>
3. 3. Let’s look at some examples of opposites! <ul><li>-4 and +4 </li></ul><ul><li>-2 and +2 </li></ul><ul><li>-5 and +5 </li></ul>
4. 4. Integers can also represent situations <ul><li>Sarah went up four steps </li></ul><ul><li>The temperature is twelve below zero. </li></ul><ul><li>The elevation of the mountain is 52,000 feet </li></ul><ul><li>+4 </li></ul><ul><li>-12 </li></ul><ul><li>+52,000 </li></ul>
5. 5. Absolute Value is… <ul><li>The distance a number is from zero on the number line </li></ul>
6. 6. So…. <ul><li>Absolute value is shown by two bars on either side of an integer. </li></ul><ul><li>The absolute value of the number is really just the number without a sign (or neither negative nor positive) </li></ul><ul><li>4 </li></ul>
7. 7. Let’s watch a video to help us more!
8. 9. That should get us started! <ul><li>Your assignment is on the board! </li></ul>
