A brand new addition to our 'Destroy This Book' series is the mind-boggling Destroy This Book in the Name of Maths: Pythagoras Edition.

Perfect for inquisitive children who love to have fun, there are a dozen press-out projects to create in this book, demonstrating some of the best bits of maths.

Projects include fiery flexagons, mathemagical card tricks and mind-bending Moebius strips.

There are also lots of fascinating facts, colouring and doodling activities that will keep children busy for hours (all in the name of maths, of course).
