Teachinghistory.org is designed to help K–12 history teachers access resources and materials to improve U.S. history education in, or outside of, the classroom.
With funding from the U.S. Department of Education, the Center for History and New Media (CHNM) has created Teachinghistory.org with the goal of making history content, teaching strategies, resources, and research accessible.
