Introduction
What do you like to do in your
spare time  shop at the mall, attend a baseball game, go
to the movies, ride the rides at the amusement park, or hike
in the great outdoors? In this project, you will see how equations,
functions, and graphs can help you examine how people spend
their leisure time.
The Task
Your mathematics and social studies
teachers are working together on a research project for your
class. To complete the project, you need to research a recreational
activity and make a poster or Web page to present your information.
For example, possible choices for your project might include
shopping, attending amusement parks, attending sporting events,
attending movies, or visiting national parks. Your poster
or Web page must include the following information:
 the name of the activity you have selected;
 a brief history or the background of the activity;
 a scatter plot of some type of data for the selected activity.
You must make a prediction about the future of the activity
using this scatter plot.;
 an explanation of your prediction and how you made it
using the scatter plot;
 two more graphs, tables, calculations, or timelines about
the activity that you chose.
You will get more ideas about
completing this project in the exercises in your textbook
in Unit 3.
The Process
To successfully complete this project,
you will need to complete the following items.
Guidance
Here are some additional questions
and ideas you may want to consider for your project.
 What can the types of recreational
activities that people in a particular country do tell you
about the country and the people? For example, if a lot
of people in the U.S. spend money at malls frequently, what
can you tell about the amount of money that people in the
U.S. earn?
 Research other countries to determine
what types of activities they do in their spare time.
 How do mathematics and social studies
fit together in this project?
Conclusion
Here are some ideas for concluding
your project.
 Present your project to your class
or at a family night.
 Present the information on a Web
page. Have other students critique your project and help
you to make improvements to your project.
 Write a onepage summary of your
project, including what you have learned from researching
this topic.
Questions
Lesson 7—1
Aislyn decides to research attending sports events for her
project. She finds these data on attendance at NBA basketball
games and NFL football games. The table shows the total attendance
for each sport for the 1997 season and the average change
in attendance for the two years following 1997. Suppose the
attendance at each sport continues to increase or decrease
at these rates.
 Write an expression for the attendance
at NBA games after x years.
 Write an expression for the attendance
at NFL games after x years.
 Use the expressions in parts a
and b to write an equation to find the number of
years until the attendance at each event is approximately
the same.
 In about how many years will the
yearly attendance at the two types of events be the same?
 How can Aislyn display these data
in a scatter plot to show her prediction for when the attendance
will be about the same?
Lesson 8—8
Jacob loves to shop for clothes and sports equipment at the
mall, so he decides to research shopping malls for his project.
The table shows the number of shopping malls in the U.S. from
1997 through 2000. Column 1 shows the year, Column 2 shows the
number of years since 1997, and Column 3 shows the number of
malls.
 Make a scatter plot of the data
by plotting the ordered pairs (years since 1997, number
of shopping malls).
 Explain why the scatter plot is
a function.
 Draw a line that approximates the
data.
 How can Jacob use the line in part
b to predict the number of shopping malls in 2010?
 Predict the number of shopping
malls in 2010. Do you think this prediction will be fairly
accurate? Why or why not?
