Unit 1 Review
Identifying Integers and their opposites
Comparing & ordering integers
Absolute Value
Greatest Common Factor
Least Common Multiple
Rational Numbers: identifying their opposites & absolute values
2
Inequalities
Greater than >
Less than <
Inequalities open towards the greater quantity
The closer a negative is to zero, the more value it has
3
Multiple Choice
4
Multiplying negatives
-(1) = -1 x 1 = -1
When you have the negative on the outside of the parentheses, give the negative a value of 1 to make it -1
The default operation is to multiply
5
Multiple Choice
6
Using a number line
Positives are on one side
Negatives are on the opposite side of the positives
0 is Neutral, it is not positive or negative
0 is referred to as sea level when using geographic elevations
7
Multiple Choice
A diver went 27 feet down into the Pacific Ocean. What integer represents that dive & sea level?
8
Multiple Choice
What is the value of point B? Hint* each dash mark represents 1/5th on a number line.
9
Multiple Choice
What is the opposite of point C?
10
Multiple Choice
From 0, the farther a number goes to the right of 0 the greater it's value gets.
Also, the farther left a number goes from 0 the less value it has.
11
Absolute Value
Absolute value measures the distance to zero
Absolute Value will always be positive since it measures distance
Find the absolute value of a number when it looks like this |-2|
Example | -1 | = 1, |2| = 2
12
Multiple Choice
Which value from the picture has the greatest absolute value?
13
Open Ended
Describe if each location is above or below sea level.
Campground -812 feet ______ sea level
Gas Station 1,629 feet ________ sea level
Gift Shop 3,000 feet ______ sea level
Visitor Center -196 feet ________ sea level
14
Least Common Multiple
Multiples are the results from multiplying by an integer
When two or more numbers have a multiple in common they are known as shared multiples
The smallest multiple they share is the least common multiple, or LCM
15
Multiple Choice
16
The Distributive Property
In the expression, factor out the GCF
Find a factor both 5 and 15 share
A factor is a number that can evenly divide into another
Both 5 and 15 share a factor of 5. It is the largest factor they share, so it is the GCF
17
Multiple Choice
The greatest common factor in the expression is 5. Both numerical terms were reduced using the GCF. Which expression below shows this?
