0A classic title that has been used to teach hundreds of thousands - possibly millions - of students over the years This book is intended to act as an encouragement for children to learn their tables. On every page there are diagrams made up of small numbered areas. If that number will divide by the number being studied, then the area has to be colored. When all the target areas of a particular puzzle are colored, then the hidden picture is revealed. There are also other charts and hundred squares to colour and the book is then rounded off with a target test to confirm the progress being made.
