Turn substitution, square roots and cube roots practice into two Halloween codebreakers. Pupils substitute signed values into expressions involving squares and evaluate square and cube roots. The questions call for exact answers and careful use of operations, with the decoded message providing a satisfying finish.

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.
