I'm not sure what it is about lower elementary school students, but they don't seem to believe in the whole "raise your hand to speak" idea. I mean, sure... they believe it in theory: if I asked my whole class what they needed to do to get my attention, they would dutifully reply with a chorus of "raise your hand". But in the real world? Not so much. The kids will come right up to me if they need something. It doesn't matter that they're in first grade and have been "raising their hand" for a year and half now. I still have random students getting up out of their chairs and coming to me to ask for (fill in the blank).
So today when an office staff member came by to take a picture of me and my cooperating teacher (for a bulletin board), it was strangely fitting that I was literally waving a student out of the shot just as she clicked the button. There I was: one arm around my colleague, the other stiffly bent away from my body, shooing off a random request from a student who "forgot" to raise her hand.
I can't think of a more fitting picture to capture life in the classroom!
