Classic problem from ¬†way back – but not clear how long it’s been around (couldn’t find anything other than suggestion it’s linked to Rose church windows).

Features in the Shell Centre ‘blue’ box Problems with Patterns and Numbers¬†that introduced it into many mathematics classrooms (1984), with answers and approaches to it!

Problems with Patterns and Numbers Teachers’ Guide has the Mystic Rose (with solutions on pages 58-9) though this is not referred to in the main index.

Problems with Patterns and Numbers: Masters for Photocopying (or for IWBs).

This ‘blue’ box has some, now, well known problems – but there are still gems there that are not so well known.

Many of the problems come from much further back!
