text: what do you think is the best grade span in an elementary school? i was just wondering what your thoughts are on this.  would you say k-3, k-5, k-6, or k-8 is the best grade span for an elementary school.  anyone is welcome to answer this, but i'm especially looking for a teachers' perspective.  our school system has k-3 primary schools and i feel that the students don't have a chance to form a very strong bond at their school. we had k-5 which i thought was fine. k-3 seems... well, silly. is there a big difference in 3rd graders and 4th graders? not really. i would say stop at 4th or 5th. just my opinion, though. and, the point you bring up about "school bond" is valid. my only issue: do you want a 6th grader on the same bus as a 1st grader? if a fight would occur.... this could be a problem.
