School just started for us, so I decided that I needed a VACATION! (got the idea
here) When music started I didn't say anything, just started setting up a camping chair, then got dressed in a Hawaiian shirt, hawaiian leis, a pair of sunglasses, a big floppy hat, and I got out a drink and straw and sat down, telling the kids that summer was over for them, but my vacation had just started. I told them they were going to be in charge today instead of me and I was just going to relax.
I had a bag for each song we have been working on, with various props I had used. I then picked a kid for each song and they could look through the bag, decide what props to use and how to conduct.
This worked pretty good, but they weren't quite as independent as I had hoped, they still needed lots of help deciding, holding things, pointing at the right parts, etc. Which of course I then used to my advantage and at the end told them that apparently they weren't quite ready to replace me yet, so next week I would come back from vacation and get back to work!
