Halloween Maths Codebreaker Pack | Expanding Brackets and Substitution

Turn expanding brackets and substitution practice into two Halloween codebreakers. Pupils expand single brackets and use the constant term to crack one message, then substitute signed values into linear expressions in the second. Both sheets reward careful algebra rather than guessing from a multiple-choice list.

Each topic is a one-page pupil activity with a full A–Z decoder and its own hidden message. Use the pair for a seasonal lesson, independent practice, homework or revision. Both answer keys are on page 2 of their respective PDFs, making checking and preparation straightforward.
