Have 3 bowls:
Bowl #1 WHO (as in who is going to sing)
Bowl #2 HOW (how they are going to sing it.
Bowl #3 WHERE (where they are going to sing )
WHO: girls only, boys only, teachers only, those wearing white or black or blue or pink or brown or yellow, blond hair, brown hair, etc...
HOW: staccato (hot), forte' (loud), piano (soft), legato (smooth), stop/go, actions only, eyes closed, etc..
WHERE: sitting on chairs, backs against the wall, sitting on the floor, laying on the floor, sitting in a different chair, standing in the front, standing in a circle, etc...the kids only have by the time I count to 10 to get in position. When we are done with that song... count to 10 again and the kids must be back in their original chair.
