Most of my past experience is in private schools. And, what I will say is that my previous principal was very concerned that if s/he gave us time to work in our classrooms that we wouldn't do any work. . .So, his/her answer was to keep it deliberately super scheduled and it was "understood" that we had to stay after school or come in prior to pre-planning to get our rooms squared away.
What with my only having one opportunity this summer to visit my new classroom, I'm really hoping I get a bit of time during pre-planning to work. . .In any event, I'm SUPER prepared to hang out at school until after 7pm.
Fortunately (well, now at least) my previous classrooms haven't had much in the way of bulletin boards. My new classroom is the same! All of this plays out well for me, because I have quite a bit of handmade posterage that is ready to hang. I've posted these images before, but they are among the most popular on this blog. I should mention that one of these includes the infamous no-no board (this is not to re-start the discussion; if you want to add to that discussion please do so here).
SO, once again, here are my favorite art classroom posters.
