How to read music

I have used this video to show primary aged pupils the ideas of how to read music.

While watching Dr Wendy Brooks commenting on how videos need to be accurate, this video sprang to mind. It is a really good, the only problem is that at one point when they are accenting the notes, the actual direction of the pitch that is being played does not match the written direction. It always gets to me that such a good animated and easily accessible video for children could make such a fundamental mistake.
