How to use 'Cha Cha Slide': 'Cha Cha Slide' is a fitness song by DJ Casper. We used it for the warm up at the beggining. Details of how the movements go can be found on the web. It is best to have a leader at the front to show them how. It's also a good idea to have a large 'Left' and 'Right' on the walls so the kids know which way to move. Instructions of how to use it are listed below: > Open the presentation > Press space bar to begin > Press 'Esc' to end the presentation ps: DJ Casper has now bought out another song called 'oops upside your head' (a remake of the old one)
