Overview
Students will generate two pie charts as to their estimation of the
composition of the United States by racial groups. The first pie
chart will be their own estimation (as a class), the second will be a
pie chart generated using the actual numbers.
Concepts
- Students will work with the concept of diversity.
- Students will learn how to work with a spreadsheet.
- Students will increase their comfort level of reading data
from a chart.
Indicators
- Define the word diversity.
- Be able to identify the five major ethic groups in
America.
- Be able to input data on a spreadsheet.
- Be able to talk about the composition of the American
population.
Precomputer
- Conduct a class discussion on Diversity. Decide within the
class whether or not the United States is a diverse country.
- Discuss how similar to, or different from, the rest of the
country your classroom is.
- Brainstorm the number of categories into which the United
States can be divided into. (the chart I use has 5: European,
African-American, Hispanic, Asian, American Indians) Also
Brainstorm the total population of the United States (250 million)
This can lead into a discussion of population distribution within
the United States if you are so inclined.
- Have each student divide the population of the United States
into the five racial categories depending on their own ideas of
the composition of the country. Either by percent or by
millions--making sure that EVERYONE uses the same method.
On the computer
- Using ClarisWorks open a spreadsheet document.
- Title Cells
- A1 European
B1 African-American
C1 Hispanic
D1 Asian
E1 American Indians
It will be necessary to widen the columns for several of
these.
- Have the first student come to the computer and input their
guesses as to population under the proper headings.
- After all the students have inputted their data,
use the =sum function to add up the rows of numbers.
- Generate a Pie Chart using the students data.
- Tell the students what the actual figures are and input them
into a separate line on your spreadsheet.
- Generate a Pie Chart using the actual figures.
- Compare the two Pie Charts and discuss what they tell us.
(comparing reality with perception)
Postcomputer
- Discuss the differences in the charts.
- Have the students as a homework assignment ask their parents
to answer the same questions.
