Kindergarten teacher crowd control techniques

I watched in amazement the other day when I saw my child's kindergarten teacher calming down a rioting group of 5 year olds in a matter of seconds. Maybe there are some presentation lessons here:

• Start telling a story, build anticipation
• Lower (and not raise!) your voice
• Ask people to imagine/see/hear something
• Maintain direct personal eye contact with everyone in the room
• Ask people questions, encourage them to contribute, have audience members listen to each other, even put them on the spot (in the center of the circle of kids)

These 5 year olds are most certainly a more difficult crowd than a grown-up presentation audience...
