Tuesday, Oct 21 Lesson 6.5.2/6.5.3 Absolute Value/ Compare and
Order Integers
Slide 13
Absolute Value Objective: To find the absolute value of an
integer and how to compare and order integers.
Slide 14
Absolute Value Opposites are numbers that are the same distance
from zero in opposite directions on the number line.
Slide 15
Absolute Value What is the opposite of 4?
Slide 16
Absolute Value What is the opposite of 4? -4 is the opposite of
4
Slide 17
Absolute Value What is the opposite of -9?
Slide 18
Absolute Value What is the opposite of -9? 9 is the opposite of
-9
Slide 19
Absolute Value The sum of a number and its opposite will always
be what?
Slide 20
Absolute Value The sum of a number and its opposite will always
be what? 0
Slide 21
Absolute Value The absolute value is the distance a number is
from zero on the number line. The absolute value will always be a
positive number. InI = the absolute value of n.
Slide 22
Absolute Value I5I = 5 5 is 5 places from zero on the number
line.
Slide 23
Absolute Value I-2I = 2 -2 is 2 places from zero on the number
line.
Slide 24
Absolute Value I-7I =
Slide 25
Absolute Value I-7I = 7
Slide 26
Absolute Value I8I =
Slide 27
Absolute Value I8I = 8
Slide 28
Absolute Value I5I + I-6I =
Slide 29
Absolute Value I5I + I-6I = 5 + 6 = 11 On the homework, rewrite
the equation after solving the absolute value before performing any
operation.
Slide 30
Absolute Value I-7I I3I = Do this on your own.
Slide 31
Absolute Value I-7I I3I = 7 - 3 = 4
Slide 32
Absolute Value I-9I + I3I = Do this on your own.
Slide 33
Absolute Value I-9I + I3I = 9 + 3 = 12
Slide 34
Absolute Value I-8I I-2I = Do this on your own.
Slide 35
Absolute Value I-8I I-2I = 8 - 2 = 6
Slide 36
Absolute Value I9-2I = Do this on your own.
Slide 37
Absolute Value I9-2I = I7I = 7 When the operation is inside the
absolute value sign, perform the operation first, then determine
the absolute value.
Slide 38
Absolute Value I15-6I = Do this on your own.
Slide 39
Absolute Value I15-6I = I9I = 9
Slide 40
Absolute Value At the football game last Friday in the first
series, the first plays was a +6 yards, the second play was a -4
yards and the 3 rd play was a - 7 yards. Which play had the
greatest absolute value?
Slide 41
Absolute Value At the football game last Friday in the first
series, the first plays was a +6 yards, the second play was a -4
yards and the 3 rd play was a - 7 yards. Which play had the
greatest absolute value? I6I = 6 yds I-4I = 4 yds I-7I = 7 yds The
third play had the greatest absolute value.
Slide 42
Absolute Value A seagull is flying 17 ft about sea level. Dan
is diving 13 ft below sea level. What is the distance between Dan
and the seagull?
Slide 43
Absolute Value A seagull is flying 17 ft about sea level. Dan
is diving 13 ft below sea level. What is the distance between Dan
and the seagull? l +17l + l-13l 17 + 13 = 30 ft
Slide 44
Absolute Value A game show contestant answered a question and
lost 10 points. He answered another question and lost 5 points. How
many points has he lost?
Slide 45
Absolute Value A game show contestant answered a question and
lost 10 points. He answered another question and lost 5 points. How
many points has he lost? l -10l + l - 5l 10 + 5 = 15
Slide 46
Absolute Value Mei is evaluating an expression using absolute
value. Find her mistake and correct it.
Slide 47
Absolute Value Mei is evaluating an expression using absolute
value. Find her mistake and correct it. An absolute value cannot be
negative. The correct answer is 14
Slide 48
Integers The number line can be used to compare and order
integers. On a number line, the number to the left is always less
than the number to the right.
Slide 49
Integers An inequality is when two values are not equal. e.g. 6
> 3
Slide 50
Integers Replace with to make the statement true. -9 -4
Slide 51
Integers Replace with to make the statement true. -9 -4
Integers Replace with to make the statement true. 0 -5 -5 0
>
Slide 54
Integers Replace with to make the statement true. -6 5 -5
0
Slide 55
Integers Replace with to make the statement true. -6 5 -5 0
Since -6 is to the left of 5 it is less than 5. -5 -4 is further to
the right than -5, so Justin has the higher score.
Slide 60
Integers The temperature on Tuesday was 2F. The temperature on
Wednesday was -2F. Write and inequality to compare the
temperatures. Explain the meaning of the inequality.
Slide 61
Integers The temperature on Tuesday was 2F. The temperature on
Wednesday was -2F. Write and inequality to compare the
temperatures. Explain the meaning of the inequality. 2 > -2 2 is
further to the right than -2, so Tuesdays temperature was
higher.
Slide 62
Integers Order 4, 8, 0, -5 from least to greatest Do this on
your own. (use your number line)
Slide 63
Integers Order {4, 8, 0, -5} from least to greatest -5 0 4 8 Is
least to greatest right to left or left to right?
Slide 64
Integers Order {4, 8, 0, -5} from least to greatest -5 0 4 8
{-5,0,4,8}
Slide 65
Integers Order {1, -3.5, 4, -1.5} from least to greatest
Slide 66
Integers Order {1, -3.5, 4, -1.5} from least to greatest {-3.5,
-1.5, 1. 4}
Slide 67
Compare and Order Integers The table shows the lowest elevation
for several continents. Order the elevations from least to
greatest. Do this on your own.
Slide 68
Compare and Order Integers The table shows the lowest elevation
for several continents. Order the elevations from least to
greatest. {-418, -156, -105, -86, -28, -12}
Slide 69

trip at Mt. Washington. They return from the slopes at 6PM. By 9PM
the temperature had fallen 18 to the days low temperature of -8F.
What was the temperature at 6PM? Do this on your own.
Slide 70

Slide 73
Compare and Order Integers The table shows the amount of time
it takes Henry to do different activities before going to soccer
practice. If he needs to be at practice at 8:15AM, what time should
he wake up in the morning? Or you could have added the times in the
table, 15 + 35 + 10 + 20 = 80 minutes Then figure out what time is
80 minutes before 8:15. 80 minutes is 1 hour and 2o minutes. An
hour before 8:15AM is 7:15. 20 minutes before that is 6:55AM
