Most people have taken part in treasure hunts of various kinds in different social contexts. What perhaps is not generally realized 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 organizing them are understood, they can be adapted easily to the circumstances. In this book, there are six complete treasure hunts, four ready to photocopy directly and suggestions, ideas and templates for many more.
