Bit of a conundrum here. I have four Chromebooks in my classroom. All year long there hasn't been a problem and they've been treated well by the students until today. Two kids fought over one, dropping it and cracking the screen. Another kid, and this is still a mystery, colored all over another screen. These are 2nd graders. My first reaction is to prohibit Chromebooks and other technology for the remainder of the year. But that seems counter-educational. What's the way to go?
