fotobabble and the genitive case

I have a project using fotobabble and the genitive case for German 2. Students choose a picture and then describe it with 5 sentences using genitive expressions. They have added their description, speaking the 5 sentences with proper vocabulary, grammar and pronunciation. Students can then email or upload their fotobabble to their facebook page. I chose to do this with fotobabble due to it's user-friendly features and the ability to speak and upload pictures using only the computer or hand-held device.
