Following Dave’s post on Youtube gap fill activities, I’d also like to contribute with a practical idea: The Vagalume [http://vagalume.uol.com.br/] APRENDA feature. Having selected the lyrics to a song, you can add gaps to it by clicking the aprenda button. Unfortunately, you cannot control which words will be removed; nevertheless it’s still a good filler if you have some time left near the end of your lesson or when opportunity arises. It’s especially convenient since the lyrics are usually shown side by side with video on the right.
Have a great term!
