This week's winner of a bumper box of Dubble chunky bars - the fair-trade chocolate - is Suzanne Jones, teacher and Year 9 tutor at the Dearne high school in Rotherham, South Yorkshire. She's so proud of 9SHJ, whom she inherited just before Christmas. Attendance and punctuality have improved and their sporting prowess has shot up from bottom of the league to outright winners on sports day last summer. So she's glad to have them for another year. If your class deserves a treat email firstname.lastname@example.org to tell us why, giving the name of your school and marking your message Dubble offer.
