It's 7:30 a.m. on a recent weekday, the sun is still rising and the kids at Pulaski Elementary School in Meriden, Conn., are already dancing.
They are stomping, hopping, clapping and generally "getting the shakies out," as fifth-grader Jaelinne Davis puts it.
"If we're like hyper, if we do this, then we can get better at, like, staying mellow and stuff like that," she says.
By 9 a.m., Jaelinne will be back at her normal school day with its core curriculum that is graded by a state test at the end of the year.
