uv mapping

I wanted to have a tutorial on uv mapping with help for gaming for my high school class so I finally sat down and made one. I have had 3 students work it and they seemed to have no problem but I would really like other input.
Anyone care to take a look? I was just interested in the mapping itself but would not mind adding simple helpers for other parts of it.
