What are some free kid-friendly tutorials to get started with Mindstorms Nxt 2.0? My daughter (10) got the NXT 2.0 for christmas. It doesn't really come with any tutorial. I'm looking for something she can follow which will teach her to use each of the sensors and slightly more advanced topics like executing a 90 degree turn (how to find exactly the # of rotations of each wheel to do that for your particular turning radius).

Can be any free resource (YouTube videos, etc.)
You can find some free instructions at http://www.nxtprograms.com/ and at http://thenxtstep.blogspot.com/p/building-instructions.html. But I am not sure if you can say they are kid-friendly.
