Actually you can get a better result by walking them through a play slowly, then faster and faster until they've got the muscle memory and speed to succeed. Combined with drills for strength/accuracy, and you can bring a kid up to speed pretty quickly.
Giving them the ball and letting them run is not coaching. It works for the 1st 5 minutes; then they'd probably like to have some success or learn something. Kids are like that.
The child needs to be at the right level to understand the concept before they can be coached to do it. The book is aimed for 6 year olds, so, I'm using that age. Teaching a corner kick to a 6 year old is a waste of time. (at least in North America) You are still teaching the basics of space, movement and ball control.
Ergo, playing a game is the best way for a 6 year old to learn. At this age, exposure is the key element.
