To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This was too childish to give as a present for my 11 year old grandson. The print is very large and widely spaced. The book arrived warped as though it had been in a damp place and the paper was so thin the writing on the previous page shows through. I would only recommend it for 9 / 10 year olds.
I bought this as one of three Math Inspectors books for my son to cultivate his math skills, but I'm disappointed that his language arts skills will decline due to the grammatical and spelling errors in all three books.
