I had many parents who would ask, 'how's my child doing?' and other specific questions during an open house. I wouldn't have enough time to answer these questions during the open house itself, so I would invite the parents to bring their questions to tea on Sunday afternoon after the second or third week of school. We would 'play school' so that the parents could get a taste of the curriculum, the teaching techniques and the daily scheduling. This informative and fun get-together before open house would eliminate confusion and set a positive relationship for the rest of the year.
