OMG - where have these people been on their lives? I remember being asked to brainstorm all the changes that boys and girls were noticing in their bodies (year six!). I always preface these discussions with, 'If you are not mature enough for this conversation, Mrs. S. in kindergarten is happy to have you,', and that sorted them out...sort of! Anyway, the ideas were put on a whiteboard and because the students didn't get to write them all down, I left them there for the next day. Anyway, good old Catholic school that it was, all was erased just in case the janitor, with kids of his own, might be upset!!
