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 my grandaughter's favourite when she was small, now we have a 2 year-old honorary grandaughter so I have bought this book for her and my grandaughter will read it to her. It is a funny book and teaches counting.
