Most people have taken part in treasure hunts of various kinds in different social contexts. What perhaps is not generally realised is just how easy and rewarding they can be to include within the mathematics curriculum. They can add variety to lessons, end of term activities, maths clubs, parent evenings or open days. Once the principles of organising them are understood, thay can be adapted easily to the circumstances. In the book there are six complete treasure hunts, four ready to photocopy directly from blackline masters and suggestions, ideas and templates for many more.
