Founded in 1991 by the Southern Poverty Law Center, Learning for Justice (formerly named Teaching Tolerance) provides free educational materials to teachers and other school practitioners in the U.S. and Canada.
Their magazine is sent to 450,000 educators twice annually and they produce free videos for the classroom. (See two examples below in Related Materials.)
Learning for Justice offers a collection of readings and lessons called Perspectives for a Diverse America.
More than 5,000 schools participate in their annual Mix It Up at Lunch Day program.
