UK version - US version also available. A classic Tarquin format that has been used to teach hundreds of thousands - possibly millions - of students over the years! This book is intended to provide a restful way for students to revise and reinforce their STATISTICS skills. On every page there are diagrams made up of small numbered areas. If that number is the answer to one of the algebra questions, then the area has to be coloured. When all the target areas of a particular puzzle are coloured, then the hidden picture is revealed.
