The units have students using the same kinds of visuals, search mechanisms, etc., that you find on CD-Roms that deal with literary works. This site seems to load more slowly that I would like but its stories are flavored with interesting and appropriate pictures. They could be printed out for use in class. To date this site has 8 fables. The summary on the search results claims that this site has 655 fables.
Some pages have some brief lesson plans teachers have used with fables.
Visitors are encouraged to submit their own lesson plans. There is a separate page for morals teachers have submitted to go with particular fables. The fables are very short and some are accompanied by RealAudio files. Something else of interest is the dictionary. Above the list of fables there is a button for that.
