What do you want to add to your physical classroom?
I want to add more types of seating! This one is easy. Whenever I am in Wal-mart or Ross or anything else that has cheap pillows or anything of that sort, I'm always checking the prices of things like dog beds (they always price them lower than big pillows) and anything else that could be considered seating because I want more alternatives for my students.
That is not to say I have a lot, because I don't. I have a large dog bed and a big fluffy pillow and a small pillow and a rug. Because using my own money limits what I can buy. But when I find a deal, I'll hop on it and buy.
What I dream of is a room full of exercise balls and big pillows and beanbag chairs and those back-rest looking things that I don't know the name for and anything else that might let my students find the right seating for them and, yes, regular chairs for students who are more comfortable that way. I want my room to communicate to students that it is a room that is different than the testing-centric rooms they have come from and might be going to, and that I want each of them to be their own person in my room and I care to find out who that person is, starting with what kind of chair they want to sit in. Or not. The floor is fine too.
