One of the Common Core elements is requiring students to better learn how to research, analyze, and use non-fiction sources including "Primary Sources" (original documents, text, books, photos, newspapers, etc). Below is a selection of websites to help you with developing units of study that include primary sources. I will be building this page as I find new resources. If you find a good one, please let me know so I can add the page to this list.
What are Primary Sources and Why Use Them?
Library of Congress Teacher Page has all sorts of useful links for teachers to help with Common Core, state standards, and using primary sources.
