The problem with teaching kids recorder is that it doesn't connect them with the music that they know. You can play most of the pop stuff on a uke if you are so inclined, and it has become the signature instrument on children's television, so the sounds that they make are sounds that they are very familiar with --and it is great for keeping a beat, which comprises about 90% of what kids hear nowadays--

This thread has inspired me--and I'm putting together materials with the idea that I'll start working with kids again--I've already ordered the Chalmers stuff--any else that anyone finds useful?
