Cartoons for the Classroom is a service of the Association of American Editorial Cartoonists. Cartoons in the Classroom offers more than one hundred lesson plans based on editorial cartoons created by the members of the AAEC. Each lesson plan is available as free pdf download. As you might expect, most of the lessons deal with current political and economic topics, but you will also find some lessons that are not time sensitive.
In addition to lesson plans Cartoons for the Classroom provides links to other cartoon resources. One of those resources is the Opper Project. The Opper Project provides lesson plans for teaching history through editorial cartoons.
Applications for Education
Editorial cartoons can make some of the most complex topics accessible to all learners. On the topic of accessibility, Cartoons for the Classroom is currently running a cartoon caption contest that is open to all US students. The contest asks students to develop a caption for a cartoon posted by Cartoons for the Classroom. The creator of the winning caption and his or her teacher will receive a copy of May it Amuse the Court, a collection of editorial cartoons about the Supreme Court and the Constitution.
