we have PTA for grades 1-8. Grades 5-8 teachers are all in the lunchroom. so say, a parent has a daughter in the 5th and 8th grade she can go from one teacher to the next without time in between (or just 1 or 2 minutes). while the first grade is in a different building so a parent will need at least 10 minutes between her 3rd grade teacher and 1st grade teacher. And 2nd - 4th grade is in classrooms so 5 minutes between grades would suffice.
