• Sean built a new sandbox and wants to fill it
  with sand. This is what he needs to know about
  his sandbox before buying the sand. Choose from
  the answers below
• The perimeter of the sandbox.
• The mass of the sandbox.
• The surface area of the sandbox.
• The volume of the sandbox.

4
What is D. The volume of the sandbox?
Explanation The amount of space inside a 3
dimensional object is known as its volume, so
that is what Sean needs to know.

• Janet wanted to put new carpeting in her bedroom.
  Of the following choices, this is the only
  possible measurement of the area of the floor in
  her room.
• 100 feet
• 100 square inches
• 100 square feet
• 100 cubic feet

6
What is C. 100 square feet
Explanation Janet needs to know the area of her
floor. Area is always expressed in square units.
100 square inches would be much too small for
her bedroom, so the only possible answer would be
100 square feet.

• Judy covered a rectangular shaped box with
  wrapping paper. Of the following choices, this
  is what she covered of the box.
• Perimeter of the box
• Surface Area of the box
• Volume of the box
• Circumference of the box

8
What is B. Surface Area of the box?
Explanation Surface area is the sum of all the
areas of the sides. In this case, Judy is
covering the outside faces of the box with
wrapping paper, so she covered the surface area
of the box.

• Mr. Brown is putting a fence around his yard so
  his dog cannot get out. Of the following
  measurements, this is a possible amount of
  fencing that he would buy
• 140 centimeters
• 140 yards
• 140 square yards
• 140 cubic yards

10
What is B. 140 yards?
Explanation Mr. Brown needs to know the length
of the fence he needs, so his answer cant be
square yards (which is an answer for area) or
cubic yards (which is an answer for volume). The
only possible answers are 140 centimeters or 140
yards. 140 centimeters is much too short, so 140
yards has to be the answer.
11
The prism to the left is made up of 1 centimeter
cubes. One of the cubes is missing. This is the
volume of the prism.
12
What is 47 cubic centimeters?
Explanation The bottom layer has 4 cubes going
across and 3 cubes in depth. That means there
are 12 cubes on the bottom layer. There are 4
layers all together, with 12 cubes in each layer.
4 x 12 48, but 1 cube is missing, so the
answer has to be 47 cubic centimeters.
13
This is the ordered pair where the blue dot is
located on the coordinate grid to the left.
14
What is (2, 5)?
15
Jill was drawing a rectangle on a coordinate
grid. She put three of the points in the
locations shown. This the coordinate where the
fourth point needs to be.
16
What is (5, 3)?
17
Joe wanted to draw a parallelogram on the grid.
She put in the first three points. This is the
coordinate where she should put in the fourth
point.
18
What is (-4, 3)?
19
Each square on the grid is 1 square centimeter.
This is the area of the blue rectangle pictured
on the grid.
20
What is 6 square centimeters?
21
Sam drew the triangle in blue on the grid to the
left. If each square on the grid is 1 square
centimeter, this is the area of the blue
triangle.
22
What is 6 square centimeters?

• Look at the following groups of numbers. This is
  the group that has the numbers in order from
  least to greatest.
• 43, ½ , 0.52, ¼, 87
• ¼ , 0.52, ½ , 87, 43
• 87, 0.52, ½ , 43, ¼
• ¼ , 43, ½ , 0.52, 87

Sally cut a cake into 8 equal pieces. She gave
her mom 2 pieces and her dad 1 piece. This is
the percent of the cake she had left.

Tony made a plate of cookies. One fourth of the
cookies were chocolate chip, 0.6 of the cookies
were peanut butter, and the rest of the cookies
were oatmeal. This is the percent of the cookies
that were oatmeal.

Alex has a spinner divided into 8 equal parts
with the numbers 1 8 on each part. He spins
the spinner one time. This is the probability,
expressed as a percent, that he will spin a
number that is a factor of 8.
34
What is 50?
35
The spinner to the left is divided into 5 equal
parts. The spinner is spun 1000 times.
According to theoretical probability, this is the
number of times it should land on the letter A.
36
What is 200 times?
37
Mr. Linden wrote all the letters in his last name
on 6 different pieces of paper. He then put the
6 pieces of paper in a paper bag and took 1 piece
out at random. This is the probability,
expressed as a lowest term fraction, that the
letter he took out was the letter n.

Andy has 20 marbles in a bag. 10 of them are
red, eight are black, and the rest are blue.
Andy plans to take out a marble out of the bag,
record its color, and then return the marble to
the bag. He plans on doing this 10 times.
According to theoretical probability, this is the
number of times he should pull out a blue marble
out of the 10 times.
