M's first grade class did a series of songs that was about a trip to the zoo. Here is the intro song:
N's 4th grade class did a long complicated skit about epic battles. When we asked him what it was about, he said he didn't know. Here is the sword fight scene:
The skit ended with a nice song (camera ran out of batteries, but you get the idea):
We really have no idea what was going on, but it was a lot of fun!
One thing we noticed is how much time was spent at school learning parts, and how seriously everyone was. Part of every day for the last few weeks has been learning the songs and practicing on stage. The kids all did a great job. I honestly think that you would have a hard time finding such well-behaved kids (and well-organized and well-disciplined) in the US. Its just a different ethic here. Everyone took it very seriously. And looking at M's class songs, where everyone was doing the motions in unison, it was really well done.
