This is a fun activity to use with the song Aikendrum. If you haven't heard it you can listen to it here: http://www.youtube.com/watch?v=g3ggYGn8ssw
I use this activity with K-2 students. I first teach them the first verse and the chorus and we add some simple actions/tap beat. I then have students go up to the smartboard and add items onto Aikendrum for his eyes, nose, mouth, ears, and hair. We then sing through the entire song with all the verses. The kids think this activity is pretty silly and they LOVE it!
