A new poll found 40% of parents have done their kids' homework FOR them at least once. But maybe they'd be better off on their own . . . because half of parents admit even THEY struggle with it. 50% of parents have a hard time understanding their kids' homework assignments across ALL subjects. Math is the one kids tend to ask for help with the most though. The survey also looked at how we BRIBE our kids to get their homework done. The most common thing we offer is to pay for stuff like movie tickets. Extra time for things like video games is next, and cold hard cash also ranked high.
