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.
Didn't really find this very helpful and my Grandsons not that interested either. Some questionable examples for Kindergarten and Preschool children are X - "An X-ray fish" - really! and Y - "A Yak". The more well know animals for children are drawn in cartoon character method which I didn't really like either.
This book was absolutely first rate. It is simple and easy to follow. It has little stories that you can read to your child or with your child with beautiful and fun illustrations. Your little one's are going to love this book.
