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:
A. The perimeter of the sandbox.
B. The mass of the sandbox.
C. The surface area of the sandbox.
D. The volume of the sandbox.
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.
A. 100 feet
B. 100 square inches
C. 100 square feet
D. 100 cubic feet
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.
A.
B.
C.
D.
Perimeter of the box
Surface Area of the box
Volume of the box
Circumference of the box
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:
A. 140 centimeters
B. 140 yards
C. 140 square yards
D. 140 cubic yards
What is
B. 140 yards?
Explanation: Mr. Brown needs to know the length of the fence
he needs, so his answer can’t 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.
A fifth grade student at Leighton made the greatest
Mother’s Day present possible. The student wrote a
note on a piece of paper that said, “Mom, my present
to you is that I will always keep my room clean so you
never have to nag me about it.” Then, the student put
the note in the box and wrapped the box with
wrapping paper. Of the following, this could be the
amount of wrapping paper the student needed.
A.
B.
C.
D.
225 centimeters
225 square centimeters
225 cubic centimeters
225
What is
B. 225 square centimeters?
Explanation: To wrap the box, you need to know the
area of each of the faces of the box. Area is always
expressed using the word square.
Note to students: This would be a great present!!
This is the
ordered
pair where
the blue
dot is
located on
the
coordinate
grid to the
left.
What is
(2, 5)?
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.
What is
(5, 3)?
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.
What is
(-4, 3)?
An ant needed to
travel from one
blue dot to the
other blue dot in
the grid that is
shown. The ant
could only travel
on grid lines. If
the distance
between each
grid line on the
grid is 1 cm., this
is the shortest
distance the ant
could travel.
What is
10 centimeters?
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.
What is
6 square
centimeters?
Explanation: The base of the triangle is 3 centimeters and the
height of the triangle is 4 centimeters. To find the area of a triangle,
you need to multiply the base and the height, and then divide by 2.
Look at the following groups of numbers.
This is the group that has the numbers in
order from least to greatest.
A. 43%, ½ , 0.52, ¼, 87%
B. ¼ , 0.52, ½ , 87%, 43%
C. 87%, 0.52, ½ , 43%, ¼
D. ¼ , 43%, ½ , 0.52, 87%
What is
D.
¼ , 43%, ½ , 0.52, 87%?
Sally cut a cake into 8 equal

The figure to the
left is a square.
Julie put her finger
on Point A. She
moved her finger
from Point A to
Point B to Point C
to Point D. This is
the percentage of
the way she went
around the figure.
What is
75% of the way
around the figure?
Look at the drawing above. This is the
percentage of boxes that have a
shape in them.
What is
33 1/3 %?
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.

15%?
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.
What is
50%?
Explanation: The numbers 1, 2, 4, and 8 are all
factors of the number 8, so 4 of the 8 numbers are
factors of 8 and 4 are not. So, Alex has a 50%
chance of spinning a factor of 8.
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.
What is
200 times?
Explanation: According to theoretical probability, the spinner
should land on each section the same number of times. So, if
should land on each number 200 times since 200 x 5 = 1000.
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’.
What is
1/3?
Explanation: The word LINDEN has six
letters, but two of them are the letter N.
2/6 in lowest terms is 1/3.
Of the following choices, this is the number of
possible outcomes in the above situation.
A.
B.
C.
D.
2
6
8
12
What is
D. 12?
Explanation: To find the number of possible
combinations, you need to multiply the number of
choices for each. The coin can land on heads or
tails, so that is two choices. The cube has six
different possible choices. 6 x 2 = 12.
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.
What is
1 blue marble?
Explanation: According to the information given, 2 out
of the 20 marbles are blue, which is 10% of the marbles.
If he is going to pull out 10 different marbles, that means
that 10% of them should be blue, which is one marble.
