You can deal with bent cards and give copies of the manual, filing away an original. You can make sure all the pieces get put back in the box. You can make sure to give them to appropriate ages: High school kids (aged about 14-18) are going to be more responsible than 5th and 6th grades (ages 10-12). I mean, they let us use computers in a computer lab - you know, back when mice had an actual, easy-to-steal tracking ball. We had to turn the mice upside down so the teacher could see that we didn't steal it. Similar things can be done here and it isn't like they'll be playing games with the frequency that we used to visit the computer lab. If this all fails, though, you can play digital versions. My game group does plays online sometimes and while it might not work well with everything, it does work.
