A listing of lesson plans and multicultural classroom resources offered in many different languages, from Apache to Yiddish. Some languages require special fonts for correct display. The site is rudimentary but offers a lot of content.
Originally created for the U.S. Government, these resources are now freely available to the public. With 72 languages covered, there are plenty of resources to reinforce anyone on their path towards fluency. The lessons on this site are in PDF format, allowing you to follow along with the audio as you learn. There are workbooks available too.
