The interviewer is probably not looking for the play-by-play of how you would organize your preschooler's day, but rather a brief overview of the types of activities you would provide the students. For example, I believe that the preschool day should have a balance of indoor and outdoor, quiet and noisy, and small group, individual and large group activities. I would like to open the day with a large group activity to discuss the plan for the day and then move on to small group centers. I would plan for at least two outdoor playtimes each day, weather permitting, and close with another quiet large group activity before dismissal. I think it's most important to be flexible about schedules as a preschool teacher, though. If the children are engaged in an activity, I would have no problem continuing it and reworking the daily schedule to allow for these things.
