Bad Date Learner Guide
Watch the video Bad Date at http://matrixlearning.org and complete these activities.
An instructor guide is available at the Matrix Learning Web site.
A ratio is a comparison of two numbers.
In the Bad Date
movie, Isabella spoke
one word for every
seven words that
Kobe spoke.
:
1:7
1.
The ratio of her words to his words is one
to seven or 1:7. We generally separate the
two numbers in the ratio with a colon (:).
On her second date, Isabella spoke 36 words, and
Diego spoke only 6, for a 6:1 ratio. In other words,
she spoke six times as many words.
Fill in the table below.
Stuck? Draw a picture of Isabella and Diego to show
how many words each says on a 6:1 ratio.
A. If Isabella spoke 12 words, how many words did
Diego speak?
B. If Diego spoke 20 words, how many words did
Isabella speak?
C. What if she spoke 60 words?
D. What if he spoke 32 words?

over the weekend, how much TV did you
watch?

There are lots of situations in which 1:1 ratios are
desirable – or even required. For example, in a
basketball game, each team has 5 players on the court,
so the ratio of players is 5:5 or 1:1. Likewise, in a
football game, each team fields 11 players, so the ratio
is 1:1.
Can you think of three other situations in which a 1:1
ratio is desirable?
A.______________________________________________________________________
B. ______________________________________________________________________
C. ______________________________________________________________________
