Two man mechanics.

[Marty Rogers]

Bart: Congratulations that you have a young daughter willing to give it a try! The initial mechanic for a FOUL is "arm straight up with closed fist, blow whistle at the same time, then birddog (direct other arm toward fouler's hips)." The calling ref reports the foul to the table (where they can hear color and # of player). Then the two refs will switch positions (lead becomes trail, trail becomes lead). If you are tableside when you call a foul (trail), just report it, then go down and become the lead after.

That being said, remember these are pre-K children, and your daughter is very inexperienced. There may be times when you will deviate from "proper" mechanics. I'm sure your time will be spent teaching a lot (like just about everything!). I meant teaching the little kids, moreso than your daughter. Have fun, and good luck to the two of you.
