What does GCF mean?
What are we looking for?
When would we use GCF?
What is the GCF of 12 and 20?
GCF means Greatest Common Factor.
We are looking for the largest factor that a set or pair of numbers/objects has in common.
We would use GCF to evenly divide object between people/bags/baskets etc.
The GCF of 12 and 20 is 4. That is the greatest number of equal groups we can make if we had 12 drinks and 20 cookies.
Y= 4x + 7
Which of the following are possible values
(2, 12) (0, 7)
(7, 35) (3, 20)
(7, 35) and (0, 7)
Area of a Parallelogram
Base is 6 meters
Height is 3 meters
18 square meters
How do you find or define the Mean
What is the Mean for the following data set:
5, 5, 6, 7, 8, 11
The Mean is found by adding up all the data points then dividing by the number of data points.
The Mean is the average.
The Mean for this data set is 7
Draw a trapazoid
Are there 4 and only 4 sides?
Are two of the sides parallel?
Are two of the sides NOT parallel?
Are there 4 corners?
What does LCM mean?
What are we looking for with LCM?
When would we use LCM?
What is the LCM for 12 and 18?
LCM is Least Common Multiple.
We are looking for where the multiples will meet up.
We could use LCM to see when 2 sets match up. Like when we might have two events that might coincide.
The LCM for 12 and 18 is 36. If your Mom makes cookies every 12 days and your Dad makes brownies every 18 days, every 36 days you might get cookies and brownies on the same day.
solve for x
2x+3 = 7
x= 2
The height of a triangle with an area of 12 units squared and a base of 3 units
Height of 8 units.
(3 base * 8 height)/ 2 because it is a triangle not a rectangle = 24/2 = 12 units squared
What is the Median?
How do you find the Median for this data set:
5, 5, 6, 7, 8, 11
The Median is the middle number of a data set in counting order.
If there are an even number of data points, find the middle of the middle two numbers.
For this data set the median would be 6.5
draw a graph that shows X for less than or equal to -8
Is there a closed circle on -8?
Is the arrow pointing left, to lower numbers?
Draw a Number Line placing the following numbers in order.
- .4 0 -1
3/4 .70 1.3
-1/2 .5 1 1/4
-1 -1/2 -.4 0 .5 .70 3/4 1 1/4 1.3
A store sells shirts for $19.85 each. If you buy 3 shirts and pay with a $100 bill, how much change will you get?

Volume of water in a pool that measures
50 feet long
40 feet wide
14 feet deep
28,000 cubic feet
(The answer needs to have the correct label to be correct)
What is the Mode?
What is the mode for this data set:
5, 5, 6, 7, 8, 11
The mode is the value that occurs the most in the data set.
5 is the Mode of this data set
Draw a picture of 3 1/2 divided by 1/4
If you have 3 circles, squares, shapes, divided into 4 pieces each and a forth shape divided in half and that piece divided in half (so it is now quarters).
You should have 14 pieces.

Divide fractions
12/7 divided by 3/2 divided by 10/9
36/35

Draw a graph to show the answer to the following equation.
2x > 6
The other team checks your work:
Is there an open circle on 3?
Is your arrow pointed towards the right, higher numbers?
Height of a rectangular prism with a volume of 1344 cubic feet, square base with a side of 8 feet.
The square base means the base is
64 square feet
Divide the Volume by the area of the base and find the height:
21 ft
What are Quartiles?
What are the Quartiles for this data set:
5, 5, 6, 7, 8, 11
Quartile 1 ends on the 2nd 5
Quartile 2 ends between 6 and 7 at 6.5
Quartile 3 ends on the 8
Quartile 4 ends at the 11

What is the decimal value for the fraction 24/32 ?
.75
What are the possible values for X?
2x +3 > 7
Graph with an open or closed circle? Why
Graphed with an open circle because you can not use 2, but can use all the numbers close to it.
How do you find the area of a Trapezoid?
What would be the area of a Trapezoid with:
Base 1 = 10
Base 2 = 12
Height of 6
Find the average of Base 1 and Base 2 (to squish the trapezoid into a rectangle), then multiply the base average by the height.
(10+12) /2 = 11 units (base average)
11x6 = 66 units squared
What does IQR stand for?
What is the IQR for this data set
5, 5, 6, 7, 8, 11
IQR is InterQuartile Range. It is the range between the inside quartiles (1st and 3rd).
For this data set it is the range between 5 and 8.
The IQR is 3
