Halloween Maths Codebreaker Bundle | 20 Topics and Answer Keys

Bring 20 maths topics into one Halloween collection. Pupils solve each codebreaker, match their answers to a full A–Z decoder and uncover a hidden message. The puzzle gives them a reason to check their working while they practise number, fractions, decimals, percentages, ratio, indices, roots, algebra, sequences and gradients.

Use the individual one-page worksheets for a seasonal lesson, independent practice, homework or revision across different classes. Every topic has a matching answer key on page 2, so checking is quick. The bundle includes all 20 topics as individual printable PDFs, ready to select and use.
