Narrative:

My student and I were making a visual approach into P08; an un-towered airport. We sequenced into the traffic pattern with three other aircraft and a king air circling to land off of a practice instrument approach. The king air made one radio call announcing that he was circling to land and would sequence behind all of the traffic already in the pattern. As we were stabilizing on the base turn of the pattern; we looked up and saw the king air; on a very short and low downwind approximately within 100 feet off our wing. We broke off the approach and began climbing and turning away.
