They’re celebrating a New England sports victory all their own at the Elm Street School. The elementary school of 420 students is New England’s grand prize winner of the NFL Play60 Super School contest, sponsored by the National Football League. The school will receive $10,000 and a visit on Dec. 3 from some New England Patriots players. The contest is part of the NFL’s campaign to encourage children to be physically active an hour a day as a way to combat childhood obesity. The school dedicates a month each spring to fitness, as well as encouraging healthy eating with a school garden. “We’re very excited, thrilled,” said principal Mary Grinavic, who said the school hasn’t decided how to spend the prize money. She said Patriots owner Robert Kraft called on Halloween with the news. “He said it was a pleasure to recognize people doing really good things for kids in the Patriots’ backyard. We know we’re doing good things, but it’s always an honor to be recognized from outside,” Grinavic said.
