1. 1.1 Integers and Absolute Value
(Clickers)

2. Integers Counting numbers, their opposites, and zero
{…-3, -2, -1, 0, 1, 2, 3, …}
NO fractions or decimals
Can be split into 3 groups
Positive Integers {1, 2, 3, …}
Negative Integers {…, -3, -2, -1}
Zero {0}
Why is zero in a group by itself?
It is neither positive nor negative.
Try it!

3. Number Lines Integers are used to label number lines.
What do the arrows mean?
The numbers go on forever in both directions
Try it!

4. Graphing
4, -2, 5
Use a dot!

5. The distance a number is from zero on a number line
Absolute Value
The distance a number is from zero on a number line
For example
│2│ = 2
2 units
Because…

6. Absolute Value │–6│ = 6 NOTE: distances are always positive, therefore
Also…
│–6│ = 6
6 units
Because…
NOTE: distances are always positive, therefore
absolute value is always positive

7. Find the Absolute Value
│–41│ = 41
│–17│ = 17
Try it!

8. Find the Absolute Value
│23│ = 23
│54│ = 54
Try it!

9. < Compare using <, >, or = –3 ___ 5 Because…

10. < Compare using <, >, or = –6 ___ –2 Because…
Try it!

11. Compare using <, >, or =
│–2│ ___ –1 2
Try it!

12. Compare using <, >, or =
│–8│ ___ 8 = 8
Try it!

13. Compare using <, >, or =
│4 │ ___ │–5 │
< 4 5
Try it!
