0A 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 algebra 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 colored. When all the target areas of a particular puzzle are colored, then the hidden picture is revealed.
