If you are skeptical about entering contests to bring in some money for your school, talk to Linda Golden. This PTA president just won a $100,000 education grant for her school, Fountain Woods Elementary School in Burlington Township, N.J., from a contest hosted on “The Ellen DeGeneres Show’’ and sponsored by Target. Golden said she is like many of us who have little hope of winning. She had entered other contests with no luck. Still, she decided this one was worth a try. School officials are obviously thrilled and now have the enviable task of figuring out how to spend the money. The New Jersey school was one of 50 to receive this Target grant. This contest is the latest in a series of education initiatives underway at the retailing giant, which reportedly plans to donate about a $1 billion to education by 2015. (Also, Target is the sponsor of our Family Reading Night kits.) Contests like this are becoming increasingly popular. We recently posted a story about how parents are responding to  social-media driven contests. As Linda Golden can attest, they’re certainly great when you win!
