Year 3–4 Christmas maths mystery: The missing puddings, with a complete checker-verified answer key. English only. Pupils solve 48 calculations on six clue sheets and use a record sheet to eliminate suspects, places and times until one unique solution remains. This is a clue-trail mystery, not a colour-by-number or mystery-picture mosaic. Money questions use pence only. Who it is for: Years 3 to 4 (ages 7–9). There is no Chinese in this pack.
What’s included: a 15-page A4 PDF (licence page included), with cover and teacher notes, the worksheets or texts listed above, and a complete answer key. Print A4 at actual size / 100%. Price £3.00. A black-and-white ink-saver edition is included in the Lesson Planned zip.
How answers were checked: a second, independent function recomputed every answer from the stored calculation, and the unique mystery solution was confirmed by code.
AI disclosure: parts of the text and layout were prepared with AI assistance. All graphics are original code-drawn shapes; there are no AI images.

This is independent classroom maths practice. It is not a SATs paper.
