Ecology and population studies are among the most important curriculum standards of the NCSS. Population Connection has aligned its various lessons with NCSS national standards. The NCSS standard “People, Places, and Environments” aligns with the state standards of history and geography. Both the state and NCSS provide K-12 grade alignment. Social studies teachers nationwide are able to use the NCSS standards that Population Connection has provided to align the many lessons with NCSS national standards and state standards. Each of the following three lessons is designed for the elementary classroom teachers to integrate social studies with other elementary content. All three lessons have been field-tested and provide an overview, procedures, objectives, standards, skills and materials, discussion questions, and extension activities.
