Not as good as other Carol Vorderman books but great value at £7.
I am a fan of Carol Vorderman books, we have used them for science and maths mainly for the last 4 years. I bought this set for my foundation stage son and immediately noticed the thinness and lack of content compared to her other books. They are great value for £7 and as my son is only in reception, it's just a little something to do whilst his brother does his homework, but I would spend more and buy the subject specific books from year 1.
