Convincing 6th graders not to drop out?

I have a tutoring job at a middle school, and I go to seven different clrooms throughout the day. In my fourth period cl, the teacher sends four or so kids, usually the same, to the library to catch up on homework. Yesterday four of these students said they plan to drop out because they don't want to do the work. I tried to talk to them about it, but they're not listening. I try to make the work bearable by acting it out, writing the steps, or doing anything to catch their attention enough for them to get their work done. But their minds are already made up. I really need some more solutions here. I don't want to give up on them, but I'm running out of ideas. They're only eleven years old, and don't care if they stay at home the rest of their lifes, or only get a job at McDonalds. One girl said that she only made it through the fifth grade by cheating. There's so much they need to understand to even catch them up to the sixth grade, but they're not budging. Any solutions to get them willing to do the work, and possibly convince them not to drop out?
