A history of La Marseilaaise which can be used with all levels of French learners. It is simple enough, for all to understand, and yet no matter the level, everyone will learn something new.
I reference Delacroix's Liberty painting, and also name a Beatles song that was influenced by it. Perhaps you and your class can come up with ideas why the Beatles chose to use it in their song.
The song is as revolutionary and inspirational today as it ever was!
Vive la France!
