What do you know so far?
You are about to watch a video about two teens who helped start a quirky math museum in their town. The video will help you learn all about ordering and comparing integers.
But first, take this short quiz to see where you are. It’s OK if you aren’t sure of the answers.
After the video, you will do three practice problems, then take another short quiz so you can compare how you did against where you started.
1
As you move left on a standard number line, how do the values of the numbers change?

Get bigger
b

2
Which of these numbers is smallest? (They are not in any particular order below.)
a

c

d

At the Plusville Math Museum, the exhibit cases for the Geometry of Snowflakes must be chilled to ensure the objects don’t melt. When the museum is closed, the temperature in the cases is set at -12 degrees Celsius. When the museum is open, however, the temperature must be set at -20 degrees Celsius to offset the heat from the visitors’ bodies in the room.
a
-20 is equal to -12
b
-20 is greater than -12
c
-20 is less than -12
4
Select the correct symbol to make the following statement true, since -20 is less than -12:
a
>
b
<
c
-
d
=

The Plusville City Council has set height restrictions on buildings in the neighborhood where the museum will be located, so the museum’s architect has designed an entrance on level 0, six floors above the entrance level for exhibits, and six underground floors for more exhibits. Order these floors on the directory from least to greatest.
a
0, -2, 5, -6
b
5, 0, -2, -6
c
-6, -2, 0, 5
d
5, -2, -6, 0

b
