I did the Kindergarten group at our church last year, and it was set up to have activities to go along with the story each day. I was lucky enough to have 2 rooms, so one room I set up as the locker room (I don't know what I'll call it this year, but it will probably be decorated like a beach)- where we had the lesson. Then before going to the other room where I had all the activities set up, I divided the group up by colors. I simply cut about four colors of construction paper into strips, mixed them up, and passed them out. I had the green group line up with a certain leader who would put a green dot on their hand with a marker, and take them to their station.

This helped each group stay together and know where to go. It also kept friends (or partners in crime!) separated.

Hope that made sense and will help some!
