Halloween Maths Codebreaker Pack | Coordinate Gradients and Sequences

Turn gradients and arithmetic sequences practice into two Halloween codebreakers. Pupils find gradients from pairs of coordinates and calculate later terms in arithmetic sequences. This pair gives two compact, independent activities for algebra and coordinate revision.

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.
