Halloween Maths Codebreaker Pack | Order of Operations and Negative Numbers

Turn BIDMAS and negative numbers practice into two Halloween codebreakers. Pupils have to apply the order of operations and handle signed numbers accurately. The decoded messages give them an immediate reason to check a misplaced sign or a calculation done in the wrong order.

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.

Digital PDF download; no physical item is supplied. Includes A4 and US Letter versions.
