Margaret Fo is head of Moorland first school in Milton Keynes, where children already have a mid-morning snack because they sometimes miss breakfast and it helps their concentration. She thinks our bumper box of Dubble bars would help to kick-start a discussion about how fair-trade food can be tasty. If your class deserves a treat, email friday@tes.co.uk to tell us why, giving the name of your school and marking your message Dubble offer. For information on fair trade, go to www.dubble.co.uk.
