I have several students who have recently gotten it it into their heads they don't need chairs. Theoretically, I have no problem with this. These are the kids that could probably do very well to stand. But, aye, there's the rub. By standing at our typical first-grader-sized desks, they eventually find themselves doing barrel rolls and such over the desks' surface. I suspect a proper desk mean for standing would help the problem, but we can only raise them so high and I'm low on teacher monies.
