Halloween Maths Codebreaker Pack | Decimals and Rounding

Turn decimal operations and rounding practice into two Halloween codebreakers. Give pupils practice with all four decimal operations, then switch to rounding to place values and significant figures. The two different skills make a useful mixed number lesson or focused homework pair.

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.
