Rebecca sent in this feedback about the Last Person Standing Game. You might want to try it in your problem JHS classes!

This game changed a group of surly, pubescent second year JH girls into a smiley, screaming fun-loving bunch who wouldn’t let the game finish!  We played for about 20 minutes.  Problems were me running out of simple questions and a few of the “different” girls who refused to answer and their row/column felt unfairly disadvantaged.  Obviously these could be prevented by preparing lots of questions in advance and maybe having everyone move one seat to their right after 5/10 questions.

There’s also a page of questions on the site that might help!
