Bar codes have a pattern in their digits to help detect errors. A magic trick can be done where one person reads out all but the final digit on the bar code of a product, and the second person ‘predicts’ this final digit (the check digit) by using the pattern in the digits. Teach your class to do this trick and get them thinking about the maths that makes the trick work.
