Population pyramids and us
http://www.nationalgeographic.com/xpeditions/lessons/09/g68/pyramids.html
A lesson plan for grade 6 Mathematics and Social Studies
In this Xpeditions lesson, students explore how geographers use a population pyramid to examine the structure of a population and the potential growth in a particular area. Students work with partners to create population pyramids to describe certain characteristics of a demographic.
Students will:
- understand the demographic structure of a population; and
- be able to describe population structure using population pyramids.
Xpeditions provides a link to U.S. Census data, detailed instructions for completing the lesson, and suggestions for assessment and extension activities.
