The Gummy Bear Song
My thought is that you could show this to kids "just for fun" and then secretly sneak in a guided listening lesson. Especially because of the distinctive actions and changes in music between sections, the song could so easily be used to teach form. The actions help kids identify when musical passages change which makes mapping out the song pretty easy. I might start by showing my students the song and having them perform the actions along with the video. Then the second time through we could stop as we went and map out the different sections until we had a completed form.
And if nothing else, maybe this could give you some ideas of fun and funny actions to incorporate into your next performance!
Follow-up with the Dinosaur stomp video was an easy and natural next step. In the next lesson we might read the book again and do actions and then try out the video and see how it gets us to move our bodies again in new and fun ways. The actions are repetitive and the song is a hoot. Check it out, I think you'll like it. Oh... and if you like Dinosaur stomp then you'd probably better check out "Fanny Pack," also by Koo Koo Kangaroo.
