I bought this book for my ten year old daughter who has significant problems with spelling. I looked at dyslexia dictionaries but they didn't seem to be very helpful. This one is very good, you think how a word is spelt starting with the first couple of letter sounds and how you might spell it, then look it up, it gives you the spelling you THINK it is with the CORRECT one next to it. Brilliant!
The book is colour coded so you know if the word is correct or not. We have used a highlighter pen for easy access to the words which she struggles with repeatedly.
My only negative point is that it is quite a big book containing pretty much all the words, which might seem a bit daunting to a young person struggling with spelling, it would be fantastic if there was a junior version of this book.
Having said that my daughter will keep this book all the way through secondary school, so I am very pleased with it.
