Although the book appears to be by Carol Vorderman, (one of the reasons I purchased it) Her name is not listed as the AUTHOR in the back of the book!! the book is written by Holly Beaumont. It seems Carol's name only appears on the front cover for advertising purpose. Even being linked to Carol, I expected so much more!!
I bought this for my Grandaughter who also was not impressed, 'There's nothing NEW to help me in this book but the calculator on the front was quite fun' she said. After reading it cover to cover when it arrived, she has not shown interest since.
I think this book is aimed at children who are only just beginning to learn tables, the presentation and tips seem more appropriate for this age group.
