Does your class deserve a treat? Dubble, maker of the fair-trade chocolate bar backed by Comic Relief, is offering a box of chunky Dubble bars for a class nominated by a Friday reader every week this term. Just tell us why your kids deserve them: the most convincing answer wins. Email firstname.lastname@example.org, marking your message Dubble offer. Carmel Hadfield has just returned to St Joseph's primary school in the London borough of Bromley after surgery, and would like her Year 2 class to have the first box of Dubbles for "their thoughtfulness and kindness" during her absence.
