LONDON (Reuters) - A British school has rewarded model pupils by allowing them to have a lie-in and come in late for classes. "We try to inspire the children with some imaginative projects — not only to ensure their good behaviour but to raise their achievements," said Graham Newman, deputy headmaster at Prestwich school in Manchester, northern England. So children who perform well are being given a chance to snatch some extra time in bed, with the full agreement of their parents and teachers. "In the past couple of weeks, about 10 percent of the school population — about 80 children — were given permission. It was about an hour and half," Newman told BBC Radio on Monday. "They missed their first lesson and they actually volunteered to make up the work themselves."
