A Well
regarding the suggestion about the well - if you can get some red bricks build a small, round well in your gathering area. put a bucket in this well and fill with water. Sometime during each workshop have the children come to the well to get water (have a ladle handy). One of the gathering places in a Biblical village was the well. People, mostly the women, met there daily to get water for the day and to hear the latest news. Perhaps if everyone gathered at the well in your meeting or opening place - this is where they could hear the story of the day!
