Much to the chagrin of my former director, I believed in letting students do as much as "adults" do. On top of the standard pouring their own drinks and turning out the lights for nap, they were allowed (with teacher supervision only) to use the microwave and the classroom digital camera.
The best part about letting my students take pictures of the classroom was that I got an idea as to what their world was like. For example: I know I'm tall, but I didn't get a sense of scale until one student took a picture of me. No wonder some students got upset when I spoke to them very sternly.
Coming (hopefully) this Monday: My current classroom, transformed into an Eric Carle From Head to Toe paradise!
