I have found that my children are learning a lot about the value of the dollar and the value of time since they have signed up for the sites below and are earning some spending money of their own, maybe yours will too!
There are a few sites that are just for kids and teens, I have listed the one's I've found here. Check the full list of sites I use page for age requirements and number of accounts per household for the regular "paid to" sites for other possibilities for your teen. Quite a few of them are 13 or 14 and up. The sites listed here do require parental permission for your kids/teens to join and participate.
