The Constitutional Rights Foundation (CRF), a non-profit, non-partisan organization based in Los Angeles, seeks to educate young people about the United States Constitution, the Bill of Rights, and the benefits of civic participation. On the site, educators will find many Common Core ready resources. Readers may like to start with the Teachers tab, which navigates to the Teacher's Lounge. Here, lessons abound on such topics as the Syrian Refugee crisis, the foundations of Enlightenment philosophy, and the Federalist Papers. The CRF Blog, which boasts several dozen categories, from Africa to Intellectual Property to Urban Issues, is another strength of the site and links to related blogs and resources around the web. Of course, the aptly titled Free Lessons tab harbors many civics-related lessons drawn from various CRF publications, including U.S. Gun Policies and the Declaration of Independence, among others.
